High Accuracy Linear Li-ion Battery Charger XT2057 ■ General Description The XT2057 is a complete constant-current/ constant voltage linear charger for cell lithium-ion batteries. Its package and low external component count make the XT2057 ideally suited for portable applications. The charge current can be programmed externally with a single resistor. XT2057 determines the charge mode by detecting the battery voltage: Pre-charge, constant current charging, constant voltage charging. The charge current of pre-charging and constant –current charging is adjustable. The XT2057 is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode.
