High-Frequency Switch Mode Li-Ion Battery Charger

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 a complete Li-Ion battery-charging IC. The device combines hig 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%. The ADP3806-12.5 guarantees 12.525 V/16.7 V 0.6%, and the ADP3806 is adjustable using two external resistors to set the battery voltage.
The ADP3806 is a complete Li-Ion battery-charging IC. The device combines hig The Current Sense Amplifier has Rail-to-Rail inputs to operate accurately under low dropout and short-circuit conditions. 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.
