The LM3622AMX-4.1 is a lithium-ion battery charger controller designed for precise charging of one or two cell battery packs, with options for 4.1V or 4.2V charging voltages. It operates within a wide input voltage range of 4.5V to 24V and features a constant voltage or constant current (CVCC) configuration, ensuring optimal charging performance. The device includes a low battery drain leakage of 200nA when the input source is disconnected, which helps preserve battery life. This charger controller is capable of sinking a minimum of 15mA at the EXT pin to drive an external PNP pass transistor, and it incorporates a low-voltage detection feature that can automatically enable a "wake up charge" for deeply discharged batteries. The LM3622AMX-4.1 is housed in an 8-lead SOIC surface mount package, making it suitable for compact designs in applications such as cellular phone cradle chargers, PDA/notebook chargers, and camcorder chargers. Its temperature-compensated bandgap reference ensures stable performance across a range of operating conditions.
