BQ25040 1.2A, Single-Input, Single Cell Li-Ion BATTERY CHARGER with 50mA LDO and 2.3A Te

BQ25040 描述

The bq25040 is an 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 1.1A of charge current. The bq25040 has a single power output that charges the battery. A system load can be placed in parallel with the battery. The charge current is programmed using the ISET and EN/SET inputs. The input current limit is programmable to USB100, USB500 or a user programmed current limit up to 1.1A. Additionally, a 4.9V ±3% 50mA LDO is integrated into the IC for supplying low power external circuitry. The single-input interface (EN/SET) is used to select the charge current and to place the bq25040 into Production Test Mode.
