ISL99227FRZ Smart Power Stage Module The ISL99227FRZ is an SPS module with integrated high accuracy current and temperature monitors, has integrated high accuracy current and temperature monitors 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. The ISL99227FRZ has a 3.3V compatible tri-state PWM input, working together with multiphase PWM controllers, provides a robust solution in the event of abnormal operating conditions. Also improves 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 Intersil controllers and can be used to disable the controller during start-up and fault conditions. Smart temperature monitor module usually used for Antminer z9 / z11 / z9 mini repair, located at U4, U7, and U10 positions.
