STMicroelectronics STPMIC25 | Demoboard STEVAL-PMIC25V1

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 the core, 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 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.
