SOIC-8 Pin Description
Pin No. Pin Symbol I/O Description
1 VCC
Supply
Power input connects to a rectified high voltage source through a
current limiting series resistor and filter capacitor to ground.
Regulated 13 volt output when the charge pump is active.
2 VOUT
Output Linear Regulator Output (IXI858 = 5.0V, IXI859 = 3.3V)
3 N/C No Connect
4 IN Input Gate Driver Input
5 GATE Output Gate Driver Output. Drives external power MOSFET.
6 GND Ground Ground Return
7 VSUP I/O
Charge Pump Switch Input. Enables / disables the charge pump
output. Requires a low ESR capacitor.
8 VCAP I/O
Charge Pump Switch Output. Rectified charge pump output.
Requires a low ESR capacitor.

bsolute Maximum Ratings are stress ratings. Stresses in excess of these
ratings can cause permanent damage to the device. Functional operation of the
device at these or any other conditions beyond those indicated in the operationa
sections of this data sheet is not implied. Exposure of the device to the absolute
maximum ratings for an extended period may degrade the device and affect it
reliabilit
.
ESD Warning
ESD (electrostatic discharge) sensitive device. Although the IXI858 / IXI859 feature proprietary ESD protection circuitry, permanent
damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions are recommended to avoid
performance degradation or loss of functionality.
