描述
The STEVAL-PMIC1LKV1 is a power evaluation kit made by a STEVAL-PMIC1LM1A evaluation board and a STEVAL-USBDNGV1 USB dongle.
The STEVAL-PMIC1LM1A is a power management IC evaluation board for the highly integrated STPMIC1L, which is designed to manage the power requirements of the core, memory and interfaces of the STM32MP1x series MPU and other application microprocessors.
The STEVAL-USBDNGV1 USB dongle mounts the STM32F303CC, which provides the I2C access for the configuration of the STPMIC1L device registers, 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.
Internal routing via jumpers to satisfy any physical configuration requirements is also included.
The passive components on the board are chosen for optimal performance across most use conditions, and two push buttons and digital I/Os allow triggering of the digital controls of the device.
