ISL99360FRZ-T Electronic Components belongs to Smart Power Stage (SPS) with Integrated High Accuracy Current and Temperature Monitors.The ISL99360 and ISL99360B are Smart Power Stages (SPS) compatible with the ISL68xxx/69xxx Digital Multiphase (DMP) controllers and phase doubler (ISL6617A), respectively. 

The ISL99360 and ISL99360B 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 through a dedicated LFET control pin. An industry leading thermally enhanced 5×5 PQFN package allows minimal overall PCB real estate. 

The ISL99360FRZ-T feature a 3.3V compatible, 5.0V compatible tri-state PWM input that works together with the Renesas multiphase PWM controllers to provide a robust solution in abnormal operating conditions. The ISL99360FRZ-T also improve system performance and reliability with integrated fault 

protection of UVLO, HFET short, 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.
