Product Summary
The ADP3820ART-4.1 is a precision single cell Li-Ion battery charge controller that can be used with an external Power PMOS device to form a two-chip, low cost, low dropout linear battery charger. The ADP3820ART-4.1 is available in two voltage options to accommodate Li-Ion batteries with coke or graphite anodes. The ADP3820ART-4.1’s high accuracy (±1%) low shutdown current (1 mA) and easy charge current programming make this device especially attractive as a battery charge controller.
