BQ25050EVM
概覽
The bq25050EVM assists users in evaluating the bq25050 linear battery chargers. The User's Guide manual includes the bq25050EVM bill of materials, board layout, and schematic. The bq25050/60 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 1 A of charge current. The 30-V input voltage range with input overvoltage protections supports low-cost unregulated adapters. The bq25050/60 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 3.4 V 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 1 A using the ISET input. Additionally, a 4.9-V, 50-mA LDO is integrated into the integrated circuit (IC) for supplying low power external circuitry.
