The RP514 is a buck DC/DC converter with a Battery Monitor (BM) featuring ultra-low current and low-voltage resistance. The battery monitor divides the input voltage (VIN) into 1/3 or 1/4 to a buffer output and inputs a signal directly into the MCU’s built-in low voltage AD converter without external circuits. It is suitable for use in wearable and IoT devices that require miniaturization and long-lifetime of battery.
