The XA4217 is a complete constant-current/ constant voltage linear charger for cell lithium-ion batteries. Its package and low external component count make the XA4217 ideally suited for portable applications. The charge current can be programmed externally with a single resistor. XA4217 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 XA4217 is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode.
The XA4217 is available in the SOP -8L package (or upon request).
