DESCRIPTION

The AIC1686 is a supervisory and protection IC intended for use in off-line, multiple output power supplies. It consists of protection circuitry, power good indicator, remote ON/OFF control, and precision shunt regulator. The overvoltage protection (OVP) function is for 3.3V, 5V, and 12V outputs. In addition, an uncommitted fault detection input (PRIN) is available for use with other protection functions, such as overcurrent, undervoltage, and/or short-circuit protection of outputs.
