The MAX1736 is a simple, low-cost, single-cell lithium-ion (Li+) battery charger for small hand-held applications. When accompanied by a current-limited voltage source (such as a wall cube), the MAX1736 provides simple, accurate charging and termination control for single-cell Li+ batteries. The MAX1736EUT42 is preset to a 4.2V battery regulation voltage, while the MAX1736EUT41 is preset to 4.1V.
The MAX1736 initiates charging in one of four ways: battery insertion, charger power-up, battery voltage threshold, and by external manipulation of the EN pin. The device features an internal precharge current source that safely charges near-dead cells, as well as input-supply detection that shuts down the MAX1736 when the supply is removed to minimize battery current drain.
The MAX1736 accepts input voltages up to 22V, making it compatible with a wide range of input supplies. It has a single control input yet offers stand-alone and microprocessor-controlled operation. The MAX1736 is packaged in a small SOT23-6 package. An evaluation kit (EV kit) is available to reduce design time.
