The MC34676BEPR2 from NXP Semiconductors is a single-cell Li-Ion battery charger designed for smart handheld devices. It features dual 28 V input voltage capability, with one input optimized for USB charging and the second for AC/DC adapter power sources. This integration eliminates the need for external power source selection and input over-voltage protection circuitry.
The charger offers programmable AC charge current up to 1.2 A and USB charge current up to 400 mA, both controlled via external resistors. It provides a 5% constant current accuracy for the AC charger and a 1.0% constant voltage accuracy over the operating temperature range of -40°C to 85°C. A 4.85 V regulator is also included for powering subsystems directly. The device incorporates a charge current thermal foldback feature to limit current when internal IC temperature rises.
Packaged in a 12-UDFN (3x3) with an exposed pad, the MC34676BEPR2 supports surface mount installation. It is designed for applications such as cell phones, smartphones, PDAs, PMPs, PNDs, and other handheld portable devices requiring efficient battery management.
