MC33816AE

MC33816AE is a SMARTMOS programmable gate driver IC for precision solenoid control applications. The IC consists of five external MOSFET high-side predrivers and seven external MOSFET low-side pre-drivers. 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 overvoltage and undervoltage 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 predrivers and a high-voltage DC-DC converter low-side pre-driver. These features along with cost effective packaging, make the 33816 ideal for powertrain engine control applications. Applications include automotive (12V), truck and industrial (24V) powertrain, diesel and gasoline direct injection, transmission.
