VP

Diagnostic output. This open drain output reports the IC working condition.

The bad condition (as undervoltage, overcurrent, overtemperature) turns

the output low.

Pump oscillator voltage. At this pin is available the built-in circuitry to supply

the switch driver at about 10 V higher than VS. To use this feature, connect a

capacitor across pin 4 and pin 5. The suggested value assures a fast

transition and a minimum output drop voltage even in worse condition.

Using the four channels contemporarily, values less than 6.8 nF have to be

avoided.

Bootstrapped voltage. At this pin is available the 11 V oscillation for the

charge pump, at a typical frequency of 200 kHz.
