NEX13241PE-Q100 Production

24-channel automotive linear LED driver

NEX1324X-Q100 is an AEC-Q100 Grade 1 qualified 24-channel, 40 V high-side LED driver with up to 100 mA output current per channel, PWM and analog dimming support, and MTP for configurable depending on application requirements in automotive lighting systems.

NEX1324X-Q100 supports 8-bit output current with high accuracy from channel to channel and device to device. Channels can be used in parallel to support higher current output than 100 mA. The low dropout of the device helps mitigate the heat generation of the device itself. The device integrates UART over CAN as the digital interface to enable long distance off-board communication, which is a typical scenario for automotive exterior lighting where different lamp functions are typically located in different PCBs. NEX1324X-Q100 also supports LED open-circuit, short to ground, and single-LED short-circuit diagnostics. Additionally, a configurable watchdog automatically sets the part into Fail-Safe state when the CAN bus connection is lost.

NEX1324X-Q100 can operate at a junction temperature ranging from -40 °C to 150 °C in a thermally enhanced 38-pin HTSSOP38 package.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
