UCC27614 SLUSE26A – JUNE 2021 – REVISED AUGUST 2021 UCC27614 Single Channel 30-V, 10-A High Speed Low Side Gate Driver 1 Features 3 Description • Typical 10-A Sink 10-A Source Output Currents The UCC27614 family of devices is single channel, • Absolute Maximum VDD Voltage: 30 V high-speed, low-side gate drivers capable of • Available in 2-mm x 2-mm SON8 package effectively driving MOSFET, IGBT, SiC, and GaN • Typical 17.5-ns propagation delay power switches. UCC27614 has typical peak drive • Typical 2.5-ns rise and 4-ns fall time with 1.8-nF strength of 10 A, which helps reduce the rise and load fall time of the power switches. This results in • EN (enable) pin in SOIC8 package low switching losses and high efficiency. The small • IN- pin can be used for enable/disable functionality propagation delay of the UCC27614 helps improve • VDD independent input thresholds (TTL the dead-time optimization, pulse width utilization, compatible) control loop response, and transient performance of • Wide VDD operating range from 4.5 V to 26 V the system. This further improves the power stage • Input and enable pins capable of withstanding up efficiency. to –10 V UCC27614 can handle –10-V inputs. This helps • Output held low when inputs are floating or during improve system robustness where moderate ground VDD UVLO bouncing exists in the system. The inputs are • Under voltage lockout (UVLO) independent of supply voltage and can be connected • Can be used as inverting or non-inverting driver to most controller outputs. This allows maximum • Operating junction temperature range of –40°C to control flexibility. An independent enable signal allows 150°C the power stage to be controlled independent of the 2 Applications main control logic. The gate driver can quickly shut off the power stage if there is a fault (which requires • Telecom switch mode power supplies the power train to be turned-off) in the system. • Power factor correction (PFC) circuits The enable function can also help improve system • Solar power supplies robustness. Many high frequency switching power • Motor drives supplies exhibit high frequency noise at the gate of • High frequency line drivers the power device, which can get injected into the • Pulse transformer drivers output pin of the gate driver and can cause the driver • High power buffers INFORMATION ADVANCE to malfunction. Due to transient reverse current and reverse voltage capability of the UCC27614, the driver + VBias CVDD performs well in such conditions and such systems. UCC27614 ± EN/IN- VDD To Switch Different undervoltage lockout (UVLO) options are From Node available so that the appropriate gate driver can be Controller VDD used for a specific type of power switch such as LO IN/IN+ GaN, MOSFET, SiC MOSFET, or IGBT. The strong OUT Rg GND internal pulldown MOSFET holds the output low if the VDD voltage is below the specified UVLO threshold. OUT GND This active pulldown feature further improves system robustness. The UCC27614 10-A drive current in the 2-mm × 2-mm package improves system power density. This small package also enables optimum gate driver placement and improved layout.
