Description

The STEVAL-PMIC1K1 is a power management IC evaluation board for the highly

integrated STPMIC1, which is designed to manage the power requirements of the

core, memory and interfaces of the STM32MP1 series MPU and other application

microprocessors.

The package includes a USB dongle which provides I²C access to the configuration

registers of the STPMIC1 device, where voltage settings, power sequences,

protection thresholds and other parameters can be set.

The evaluation board includes header connectors for external access to the

embedded regulators and switches in the device, as well as internal routing via

jumpers to satisfy any physical configuration requirements.

The passive components on the board are chosen for optimal performance across

most use conditions, and three push buttons and digital I/Os allow triggering of the

digital controls of the device.
