12-channel automotive linear LED driver

NEX13120-Q100 is an AEC-Q100 Grade 1 qualified 12-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.

NEX13120-Q100 supports 8-bit output current with high accuracy from channel to channel and device to device, and channels can be used in parallel to support higher current output than 100 mA. The low dropout of the device helps eliminate 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 PCB boards. NEX13120-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 states when the CAN bus connection is lost.

NEX13120-Q100 can operate at a junction temperature range from -40 °C to +150 °C in a thermally enhanced 24-pin HTSSOP24 package. Figure 1. Typical application
