Overview

The a 12 channel gate driver IC for automotive engine control applications. The IC consist of five external MOSFET high side predrivers and seven external MOSFET low side pre-drivers. The 33816 provides a flexible solution for MOSFET's gate drive with a versatile control and optimized latency time. Gate drive, diagnosis, and protection are managed through four independent microcores, and two Code RAM and two Data RAM banks. The IC contains two internal voltage regulators with over-voltage and under-voltage monitoring and protection. There are four current sense modules and VDS monitoring for fault detection and annunciation via a serial peripheral interface (SPI). The device includes both individual charge pump outputs for each high side pre-drivers and a high-voltage DC-DC converter low side predriver. These features along with cost effective packaging, make the 33816 ideal for powertrain engine control applications. Features Battery voltage range, V < VBATT 32 V Pre-drive operating voltage 72 V High side/ low side pre-drive PWM capability 100 KHz�30 nC All pre-drivers have four selectable slew rates Eight selectable, pre-defined VDS monitoring thresholds Encryption for microcode protection Integrated 1.0 MHz back-up clock
