描述

The P91E0A is a programmable, multi-channel power management IC (PMIC) designed to meet high performance requirements and provide high-feature integration to minimize system board area and BOM cost. The PMIC includes subsystems for voltage regulation, power sequencing management, A/D conversion, GPIOs, PWMs and others. The P91E0A  is factory programmable for application specific sequencing and output voltage requirements. The device supports the serial voltage ID (SVID) interface for VCC, VNN and VDDQ (optional). The output current capability of the P91E0A solution can be increased by adding IDT’s intelligent P9148A distributed power units (DPU).
