GENERAL DESCRIPTION
The ADP3810 and ADP3811 combine a programmable current
limit with a battery voltage limit to provide a constant current,
constant voltage battery charger controller. In secondary side,
off-line applications, the output directly drives the diode side of
an optocoupler to give isolated feedback control of a primary
side PWM. The circuitry includes two gain (gm) stages, a precision 2.0 V reference, a control input buffer, an Undervoltage
Lock Out (UVLO) comparator, an output buffer and an overvoltage comparator.
