BQ25060 具有 50mA LDO 的 1A 单输入单节锂离子电池充电器
BQ25060 描述
The bq25060 is a highly integrated Li-Ion linear battery charger targeted at space-limited portable applications. It operates from either a USB port or AC Adapter and charges a single-cell Li-Ion battery with up to 1A of charge current. The 30V input voltage range with input over-voltage protections supports low-cost unregulated adapters.
The bq25060 has a single power output that charges the battery. The system load is connected to OUT. The low-battery system startup circuitry maintains OUT greater than 3.4V whenever an input source is connected. This allows the system to start-up and run whenever an input source is connected regardless of the battery voltage. The charge current is programmable up to 1A using the ISET input
