NAME

FUNCTION

1

DP

Regulated Charge-Pump Driver for GVDD. Connect to flying capacitor.

2

PGVDD

Supplies the HVINP Voltage for the Positive Charge Pump. Connect as shown in Figure 2.

3

FBPG

Feedback Input for GVDD

4

DGVDD

GVDD Discharge. Connect the output of the positive charge pump to DGVDD as shown in Figure 2.

5

POK

Power-OK. Driven high when the outputs of the gate- and source-driver power supplies are all in

regulation.

6

DGVEE

GVEE Discharge. Connect the output of the negative charge pump to DGVEE as shown in Figure 2.

7

REF

Voltage Reference. Bypass to GND with a minimum 0.1FF ceramic capacitor.

8

FBNG

Feedback Input for GVEE

9

PGVEE

Supplies the HVINN Voltage to the Negative Charge Pump for the GVEE Output. Connect as shown in

Figure 2.
