Freescale MC33816 Gate Drivers

Freescale MC33816 Gate Drivers

Freescale MC33816 is a 12 channel gate driver IC for automotive engine control applications. The IC consist of five external MOSFET high side pre-drivers and seven external MOSFET low side pre-drivers. The MC33816 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 pre-driver. These features along with cost effective packaging, make the MC33816 ideal for powertrain engine control applications.
