P91E0数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The IDT P91E0 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 P91E0 is factory programmable for application specific sequencing and output voltage requirements. The device supports the serial voltage ID (SVID) interface for VCC, VNN & VDDQ (optional). The output current capability of the P91E0 solution can be increased by adding IDT’s intelligent, P9148 distributed power unit (DPU) .
