ISL99227HRZ Integrated Circuit Chip Smart Power Stage Module With Integrated High Accuracy Current And Temperature Monitors

ISL99227HRZ Integrated Circuit Chip Smart Power Stage Module With Integrated High Accuracy Current And Temperature Monitors

Product Description Of ISL99227HRZ
ISL99227HRZ have integrated high accuracy current and temperature monitors that can be fed back to the controller and doubler to complete a multiphase DC/DC system. They simplify design and increase performance by eliminating the DCR sensing network and associated thermal compensation. Light-load efficiency is supported via a dedicated LFET control pin. An industry leading thermally enhanced 5x5 PQFN package allows minimal overall PCB real estate. The ISL99227HRZ feature a 3.3V compatible, 5.0V compatible tri-state PWM input that, working together with multiphase PWM controllers, provide a robust solution in the event of abnormal operating conditions. The ISL99227HRZ also improve system performance and reliability with integrated fault protection of UVLO, over-temperature, and overcurrent. An open-drain fault reporting pin simplifies the handshake between SPS and controllers and can be used to disable the controller during start-up and fault conditions.
