NXP Semiconductors MC33816 SMARTMOS Gate Driver
NXP Semiconductors MC33816 SMARTMOS Gate Driver is a programmable controller IC for precision solenoid control applications. The MC33816 consists of five external MOSFET high-side pre-drivers and seven external MOSFET low-side pre-drivers. The 33816 provides a flexible solution for the MOSFET 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 MC33816 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 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
