Application Diagram
(PPR, CHG, and FAST) can be simply interfaced to the system or LEDs to report the charge
status. Its internal thermal foldback control reduces the charge current automatically, whenever
the die temperature reaches the thermal limit threshold of 110°C, to keep the charger safe. When
there is no input power, or when the MC34671 is disabled, the charger draws less than a 1.0µA
leakage current from the battery.

The MC34671 can be used as a standalone Li-Ion charger.
circuit. Two LEDs indicate the charge status.
3.2
When the MC34671 is embedded in the system, the system MCU can control the charger
through the EN pin and get the charge status through PPR, CHG, and FAST pins.
