Description
The STEVAL-PMIC25V1 is a power management IC evaluation board for the highly
integrated STPMIC25, which is designed to manage the power requirements of thecore, memory and interfaces of the STM32MP2x series MPU and other application
microprocessors.
The kit includes a USB dongle, which provides I²C access to the configuration
registers of the STPMIC25 device, where voltage settings, power sequences,protection thresholds and other parameters can be set.
The evaluation board includes header connectors for external access to theembedded 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 acrossmost use conditions, and three push buttons and digital I/Os allow triggering of thedigital controls of the device.
