The ADP3806 is a complete Li-Ion battery-charging IC. The device combines high output voltage accuracy with constant current control to simplify the implementation of constant-current, constant-voltage (CCCV) chargers. The ADP3806 is available in three options: The ADP3806-12.6 guarantees the final battery voltage selected is 12.6 V or 16.8 V ±0.6%, theADP3806-12.5 guarantees 12.525 V/16.7 V ±0.6%, and the ADP3806 is adjustable using two external resistors to set the battery voltage. The current sense amplifier has rail-to-rail inputs to accurately operate under low dropout and short-circuit condi-tions. The charge current is programmable with a dc voltage on ISET. A second differential amplifier senses the system current across an external sense resistor and outputs a linear voltage on the ISYS pin. The bootstrapped synchronous driver allows the use of two NMOS transistors for lower system cost.
