VIN

OVP VOUT overcurrent, overvoltage, undervoltage, and over temp.

EN/UVLO Control • During short-circuit transient event the eFuse enables a fast-trip Logic

dVdT current threshold that terminates this rapid increase in less than 200 ns, protecting the supply. Current ILIM GND Limit • During overvoltage event on the input (VIN), the eFuse clamps the output voltage until the input falls below the OV threshold.

Example Parts: • During faults the eFuse will either remain off (latchoff version) or TPS2595 attempt to restart (auto retry version). TPS24751 • eFuses offer many features similar to load switches including TPS2660 adjustable inrush current control and reverse current protection.

Why is it needed?  When voltage is applied to capacitor the slew rate of the voltage determines the amount of charging current into a capacitor, I=C*dv/dt.  In order to prevent the backplane from having a fault the rate at which a given module’s capacitance is charged is critical (i.e. control the dv/dt).  eFuses and load switches provide a flexible way to do this. The slew rate of the output of an eFuse can be adjusted to limit the amount of current to charge up the capacitance on the board. Benefits over discrete solutions  Discrete solutions will have an exponential RC rise to the VOUT slew rate which causes large inrush current. This large current could damage the FET if the discrete circuit is not design correctly. This could also cause the backplane power supply to collapse if the inrush is too high  TI eFuse and load switch solutions have a linear rise time which removes the RC rise of the VOUT and produces a very linear rise time which limits the inrush current when the module is starting up.

TI Information – Selective Disclosure 15 Overvoltage clamping (OVC)

Overvoltage protection

Why is it needed?  The backplane power is always active. Modules can be inserted at any time in a factory environment.  When an insertion occurs on a live power supply there will be large voltage transient from the insertion (aka “hotswap”).  The system must have a way to limit this voltage spike from damaging the rest of the internal system. TI eFuses provide solutions to clamp this over voltage so that it doesn’t damage the internal circuitry of the module.

Over Voltage Clamp Response (TPS2662/3)

VOUT gets clamped at 38V during input over voltage faults

TI Information – Selective Disclosure 16 Overcurrent / short-circuit protection

Overcurrent / short-circuit protection

Why is it needed?  The backplane power supply can only supply so much current. If the backplane power supply goes into current limit then the whole backplane power will shut off which will cause the entire system to shutdown. This cannot happen!!  To prevent this, each module must limit the total amount of current from the backplane in the case of a short-circuit in the module. An eFuse can be used to limit the current.  Because of this current limit only the given module will shut off not the entire backplane. This important!  In many cases a discrete fuse is required. Another benefit of an eFuse solution is that in the event of an overcurrent fault the eFuse will limit the current before the fuse blows which saves the module from having to be returned or maintenance in the factory.  This is especially crucial if there are any firmware updates in the field that could cause an abnormal short. The eFuse will limit the current before the fuse ever blows!

TI Information – Selective Disclosure TPSx663 | Driving unknown capacitances • There could be a use case where the load that needs to be driven is an unknown capacitive load (i.e. USB port, etc…) VIN_SYS = 24V • Often times, damage occurs to the power port or the

load is not able to be powered on due to the inrush VOUT caused by the capacitive load • TPSx663 solves this by using a thermal regulation loop PGOOD at startup to control the temperature of the device to charge any capacitance

• This ensures the load powers up and the port is not I_IN damaged due to high capacitive load

System 1. 200nsec Fast-trip current limit response (Short- C protection) - When there is a surge event the voltage will rise at the input and output very quickly. ISURGE I TVS I - This will cause a large charging current which will trip the fast trip current limit and will turn Blocking HS FET CAP off the HS FET FET - See event #1, as the input rises the output remains at 24V 2. Overvoltage Protection (OVP) cutoff - To ensure that the path between input and output is shut off the OVP is triggered as well to turn off the HS FET just in case Actual Surge Performance: - See event #2 This image cannot currently be displayed. 3. 400ns Reverse Current Blocking (RCB) response - When the input begins to drop below the output during the surge event, reverse current will flow from output to input, 2 - To prevent this the 400ns reverse current blocking feature of the eFuse is enabled by 1 turning off the blocking FET 3 - The body diode of the blocking FET blocks the reverse current 4 - See event #3, the output does not discharge completely when input goes well below the output because of the RCB feature 4. Integrated dynamic Reverse Polarity Protection (RPP) - Once the input voltage goes below ground, the output of the eFuse should never go negative, else the circuitry downstream will be damaged - To prevent the output from going negative the RPP is enabled in the eFuse - It can be seen at event #4 that the input voltage (blue) is negative while the output VOUT always remains above ground Zoomed-out (10us/div)

Home Power Switches Portfolio Go Back Smart High Side Switch – Typical Features • Typical 3V to 65V operation at currents up to 4A. Smart H.S. Switch • Highly-accurate current sensing to provide real-time diag.

VIN

• An precison current mirror sources current from VIN, reflecting OVP VOUT this as voltage on the Current Sense (CS) pin.

EN/UVLO Control Logic • The CS pin can also serve as a diagnostics report pin for open dVdT load, shorted load, or over temperature condition.

Current ILIM GND Limit • These switches contain highly-adjustable and selectable current limits by connecting an external resistor. • The switch protects the load and power supply from Example Parts: overstressing during short-circuit to GND events or power-up TPS1H100-Q1 conditions. When the current threshold is reached, a closed loop TPS27S100 activates and clamps the output current to the set value. A fault TPSxH160-Q1 is then reported on the CS pin. TI Information – Selective Disclosure 49 Inductive Load Protection Inductive Load Protection

Why is it needed?

 The current flow in an inductive element cannot change instantaneous (VL = L*di/dt).  The inductive element wants to resist the change in current so it will try and continue to source current in the same direction. In a source type configuration (high-side), the VOUT node of the high side switch will rapidly want to ramp to a negative voltage.  When this VOUT node reaches a certain negative voltage the internal FET of the high-side switch will be turned ON and the power in the negative voltage spike will be dissipated through the low RDSON FET.  An integrated VDS clamp is available in the high-side switch to clamp the VDS voltage of the internal FET so that is not damaged because of overvoltage stress.
