PCF50603 is a power supply and battery management controller produced by Philips Semiconductors. It includes system control, power voltage generation, battery management and SIM card interface.
The PCF50603 is a highly integrated solution designed for mobile phones. It manages power supply generation, battery charging (supporting NiCd/NiMH or Li-ion), and includes a Subscriber Identity Module (SIM) card interface with dedicated supply regulation.
Controlled via a 400 kHz I2C-bus serial interface by a host controller, the device features multiple Linear Regulator (LDO) outputs for various system voltages. Key functions include battery voltage monitoring, backup battery charging, thermal protection, and general-purpose outputs.
