Description

General part information

BQ25040 Series

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. In Production Test Mode, the bq25040 operates as a linear regulator without a battery connected, where the output is regulated at 4.2V and supplies up to 2.3A to calibrate GSM transceivers.

The battery is charged in three phases: conditioning, constant current and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded.
