1A ,单输入,单节磷酸铁锂电池线性充电器, 50毫安LDO 1A, Single-Input, Single-Cell LiFePO4 Linear Battery Charger with 50mA LDO
The is a highly integrated LiFePO4 linear Battery Charger targeted at space-limited portable applications. It operates from either an USB port or AC Adapter and charges a single-cell LiFePO4 battery with up to 1A of charge current. The 30V input voltage range with input over-voltage protections supports low-cost unregulated adapters. It has a single power output that charges the battery and powers the system. The charge current is programmable up to 1A using the CTRL input. Additionally, a 4.9V ±10% 50mA LDO is integrated into the IC for supplying low power external circuitry. The LiFePO4 charging algorithm removes the constant voltage mode control usually present in Li-ion battery charge cycles. Instead, the battery is fast charged to the overcharge voltage and then allowed to relax to a lower float charge voltage threshold. The removal of the constant voltage control reduces charge time significantly.
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
