HIP1012A - Renesas

HIP1012A Dual Power Distribution Controller

PIN # SYMBOL FUNCTION DESCRIPTION 1 3V/12VS 3.3 V/12V Source Connect to source of associated external N-Channel MOSFET switch to sense output voltage. 2 3V/12VG 3.3V/12V Gate Connect to the gate of associated N-Channel MOSFET switch. A capacitor from this node to ground sets the turn-on ramp. At turn-on this capacitor will be charged to 17.4V by a 10.
