Power & Power Management

Overview

Description

The ISL99390R5935 and ISL99390BR5935 are 90A Smart Power Stages (SPS) that are compatible with Renesas ISL68/69xxx Digital Multiphase (DMP) controllers and phase doublers (ISL6617A), respectively. The ISL99390R5935 and ISL99390BR5935 offer best in class current sense accuracy over line, load, and temperature. When combined with a Renesas Digital PWM controller, these devices enable precision system level power management and best-in-class transient response for loadline based regulators. These devices simplify design by eliminating typical DCR sensing networks and associated thermal compensation components. The thermally enhanced 5x6 package enables high-density designs.

The ISL99390R5935 and ISL99390BR5935 feature the Renesas tri-state PWM input that works with Renesas multiphase PWM controllers and phase doublers to provide a robust solution in the event of abnormal operating conditions. The ISL99390R5935 and ISL99390BR5935 also improve system performance and reliability with integrated fault protection, including HFET overcurrent, shorted HFET, Smart Reverse Overcurrent (SROCP), Over-Temperature (OTP), and VCC Undervoltage Lockout (UVLO).
