RAA221340 40A Smart Power Stage (SPS) with Integrated High Accuracy Current and Temperature Monitors

PublishTime：2020-11-28

The RAA221340 Smart Power Stage (SPS) is compatible with the ISL68xxx/69xxx Digital Multiphase (DMP) controllers. The SPS has integrated high-accuracy current and temperature monitors that are fed back to the controller to complete a multiphase DC/DC system. The SPS simplifies design and increases performance by eliminating the DCR sensing network and associated thermal compensation. An industry leading thermally enhanced 4x5 PQFN package allows minimal overall PCB real estate.
The SPS features a 3.3V compatible tri-state PWM input that works with the Renesas multiphase PWM controllers to provide a robust solution in abnormal operating conditions. The SPS also improves system performance and reliability with integrated fault protection of UVLO, shorted HFET, over-temperature, and overcurrent. An open-drain fault reporting pin simplifies the handshake between the SPS and controllers and can disable the controller during start-up and fault conditions.
