DESCRIPTION
NC pin.
NC pin.
High voltage start-up LDO1 output and also the pin providing bias to the HV circuitry on the ISL1801. Place a 1μF ceramic
capacitor from this pin to ground as decoupling cap. Connect this pin to the output of the high voltage regulator. When the
output of the switching regulator is stable, the start-up LDO is disabled and the chip bias is supplied by the more efficient
switching regulator.
Analog ground pin for VCC1.
A resistor between this pin and ground set the peak current limit threshold for the power stage MOSFET at Phase3. A 0.01μF
capacitor can be used at this pin to filter any switching noise.
NC pin.
The phase node pin of the power stage controlled by DRIVE3. This pin should be connected to the drain of the power MOSFET
through one resistor and diode which prevent the voltage at Phase3 pin from dropping below -0.6V. Refer to the typical
application schematics starting on page 23, for correct connections.
The ground pin for the high speed driver DRIVE3.
The output of the high speed driver.
The bias input pin for both the high speed driver and the low speed driver. It is normally connected to V OUT1 . PVCC3 also
powers LDO2 which provides the bias supply for all internal control circuits.
The output of the high speed driver controlled by the BCMD signal.
The ground pin for BDRIVE.
The PWM input signal for DRIVE3.
