HIP6501ACBZ

Power Supply Controllers, Monitors Overview

The HIP6501ACBZ is a triple linear power controller companion chip designed for ACPI-compliant microprocessor and computer applications. It integrates two linear controllers, a low-current pass transistor, and monitoring functions within a 16-pin SOIC package. The device manages the 3.3V DUAL voltage plane from ATX 5VSB during sleep states (S3, S4/S5) and switches ATX 3.3V for PCI operation in active states (S0, S1). A second controller supplies memory power via an external pass transistor in active states, while an integrated pass transistor handles sleep-state power. A third controller manages the 5V DUAL plane by switching between ATX 5V and 5VSB outputs based on system state.
