SD6 Programmable Solenoid Controller 64-Pin LQFP EP Tray

The 33816 is a SMARTMOS programmable gate driver IC for precision solenoid control applications. The IC consists of five external MOSFET high-side pre-drivers 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 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 highside 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.
