Chip Introduction

Meets stringent automotive certification levels, with a maximum junction temperature of 175 degrees.

Integrates 12 MOS switches, with a single switch having a conduction resistance of 180 milliohms, and 12-bit PWM independent control for each switch.

Supports direct power supply of 12V, as well as external 5V power supply.

Based on the UART protocol, the ELINS bus supports high-speed communication at 1Mbps, and the external CAN physical layer can be connected to further enhance EMC and anti-interference capabilities.

The chip integrates a high-precision clock and optimizes EMC.

An internal watchdog is integrated into the chip to detect communication status, and if communication fails, it will enter limp home mode.

Integrated ADC to detect NTC, BIN, power supply, charge pump status, and MOS temperature. Switch slope control and switch phase control, with short circuit and open circuit protection for individual LEDs.

Main applications: dynamic daytime running lights, position lights, turn signals, and matrix headlights.
