DESCRIPTION  
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.
