CC-CV Battery Charger

The MAX1501 linear charger integrates constant temperature regulation, which minimizes charge time and accepts regulated or unregulated wall adapters with 4.5V to 13V outputs. The thermal regulation automatically adjusts the charging current to avoid excessive power dissipation and to limit PCB temperature during CC-CV charging. The 16-pin QFN package (5 mm × 5 mm) enables charge current up to 1.4A. It also charges lithium-ion (Li+) and NiMH batteries, and regulates the output voltage in a no-battery condition.
