LTC4063EDD#PBF

LINEAR TECHNOLOGY  LTC4063EDD#PBF  芯片, 电池充电控制器, 带微功率LDO稳压器, 10DFN

The is a standalone Linear Charger for single cell Li-ion batteries with an adjustable low dropout linear regulator. The adjustable LDO regulates an output voltage between 1.2 to 4.2V at up to 100mA load current. When the input supply wall adapter or USB supply is removed, the LDO regulates the output voltage without interruption. The battery charger and LDO regulator can be enabled individually. No external sense resistor or external blocking diode is required for charging due to the internal MOSFET architecture. Internal thermal feedback regulates the charge current to maintain a constant die temperature during high power operation or high ambient temperature conditions. The float voltage is fixed at 4.2V and the charge current is programmed with an external resistor. Charge termination methods include minimum charge current or maximum time.
