Power Management IC for Low-Power Microcontroller Applications

PCA9422 is a highly-integrated power management IC (PMIC), targeted to provide a full power management solution for low-power microcontroller applications or applications with small batteries.

The PCA9422 consists of a JEITA compliant linear battery charger capable of charging up to 640 mA current. PCA9422 has I²C programmable values for flexible configuration. Various built-in protection features such as input overvoltage protection, overcurrent protection and thermal protection are also provided for safe operation. PCA9422 also introduces FLEXGAUGE™ which allows for zero incremental cost battery gauging when combined with i.MX RT MCU family.
