Texas Instruments recently introduced a tiny 1,1 A Li-ion linear battery charger with integrated 50 mA low-dropout regulator to support handheld electronics. The new bq25040 comes in a small 2 x 3 mm package, and can regulate voltage within 1% accuracy from a USB port or AC adapter. The device’s integrated LDO allows a mobile application to power up instantly from an external power source, even with an empty or absent battery.
The bq25040 also saves manufacturing time and cost by eliminating the need for battery setup during the production test phase. The charger’s single-input interface selects the appropriate charge current and places the device into production test mode. The device’s 30 V input with overvoltage protection enables safe charging with unregulated or aftermarket adapters. Its selectable 100 mA or 500 mA USB current limit complies with USB standards, and input voltage dynamic power management provides protection against poor USB sources.
