描述
The P9145 is a programmable, multi-channel power management IC (PMIC) designed for the Intel® Baytrail Atom™ SoC 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 P9145 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 P9145 solution can be increased by adding Renesas intelligent, scalable, distributed power units (DPU), P9147 and P9148.
