Product Summary ASL150ySHN: Single-Phase Automotive LED Boost Driver
The ASL1500SHN is a highly integrated and flexible single phase DC-to-DC boost converter IC. It has a SPI interface allowing control & diagnostic communication with an external microcontroller.The The flexible driver can be configured via the SPI interface.
The ASL1507SHN is a single phase boost converter IC with a Limp Home mode feature. The ASL1507SHN provides an SPI interface for extensive control and diagnostic communication with an external microcontroller and integrates a customer programmable Limp Home mode. The driver IC allows configurable operation during the Limp Home mode in case SPI communication with the microcontroller has failed. Once the loss of SPI communication is detected, the Limp Home mode gets activated. During Limp-home mode, the outputs of the IC are operating according to a pre- defined conditions stored in a non-volatile memory (NVM) programmable by the customer at their end of line. The IC exits the Limp Home mode when communication is re-established and a valid exit sequence is sent by the microcontroller to the ASL1507SHN. ASL250ySHN: Dual-Phase Automotive LED Boost Driver
The. ASL2500SHN is a highly integrated and flexible two-phase DC-to-DC boost converter IC that has a SPI interface allowing control & diagnostic communication with an external microcontroller. The ASL2500SHN is a two-phase converter which can have two independent outputs. The flexible driver can be configured, via the SPI interface, as a single output converter, or with multiple combinations of number of outputs and phases.
The ASL2507SHN is a dual phase boost converter IC with a Limp Home mode feature. The ASL2507SHN provides an SPI interface for extensive control and diagnostic communication with an external microcontroller and integrates a customer programmable Limp Home mode. The driver IC allows configurable operation during the Limp Home mode in case SPI communication with the microcontroller has failed. Once the loss of SPI communication is detected, the Limp Home mode gets activated. During Limp-home mode, the outputs of the IC are operating according to a pre- defined conditions stored in a non-volatile memory (NVM) programmable by the customer at their end of line. The IC exits the Limp Home mode when communication is re-established and a valid exit sequence is sent by the microcontroller to the ASL2507SHN. ASL4500SHN: Four-Phase Automotive LED Boost Driver
The ASL4500SHN is a highly integrated and flexible four-phase DC-to-DC boost converter IC. It has an SPI interface allowing control & diagnostic communication with an external microcontroller.
It is designed primarily for use in automotive LED lighting applications and provides an optimized supply voltage for ASLx41xSHN Multi-channel LED Buck Driver. The ASL4500SHN has a fixed frequency peak current mode control with parabolic/non-linear slope compensation. It can operate with input voltages from 5.5 V to 40 V. It can be configured via SPI for output voltages of up to 80 V, to power the LED buck driver IC.
The ASL4500SHN is a four-phase converter which can have two independent outputs. The driver has the flexibility to be configured, via the SPI interface, as a single output converter, or with multiple combinations of number of outputs and phases.

4 Development tools and Ecosystem ASL45xASLx41 Multichannel LED Driver Evaluation board The ASLx500SHN and ASLx41xSHN Evaluation Boards (EVB) feature the ASL4500SHN, a highly integrated and flexible four-phase DC-to-DC boost converter IC and two ASL3416SHN three-channel buck mode LED driver ICs delivering constant average DC current. The kit is designed to drive six LED strings with 150 mA to 1.6 A and 2 V to 60 V LED string voltage. In a default application a microprocessor unit (MCU) controls the devices through a serial peripheral interface (SPI). The MCU sets the desired output voltage of the boost converter and the output currents for each individual LED strings. The ASL4500SHN and ASL3416SHN also feature several diagnostic readings to allow a detection of errors in the system.
The board is populated with a ASL4500SHN boost converter IC. As the boost converter ICs in the series are pin compatible to each other, any of the NXP boost converter ICs (ASL1500SHN, ASL2500SHN, ASL4500SHN, ASL1507SHN, ASL2507SHN, or ASL4501SHN) can be populated on the PCB. The board is populated with two ASL3416SHN buck converter ICs. As the buck converter ICs in the series are pin compatible to each other, any of the NXP buck converter ICs (ASL2416, ASL3416, ASL2417SHN, or ASL3417SHN) can be populated on the PCB.
The boost converter part of the PCB is used to generate a higher boost voltage out of the supply voltage. This boosted voltage is used to supply the buck converters which generate the output current for the LED strings.
The ASL45XASLX41 can be controlled through the S32K144EVB connected to the PC’s USB port. The NXP_LED_GUI (version 2.0 and above) program provides a GUI. The GUI allows the user to change the configuration of the devices and send commands to the ASL driver ICs. The GUI can also receive status from the ASL driver IC.
