SUBSTRATE, WHICH IS THE GROUND OF THE DEVICE.
08132- Figure 7. ADP3623/ADP3633 Pin Configuration
Table 3. ADP3623/ADP3633 Pin Function Descriptions Pin No. Mnemonic Description
1 SD Output Shutdown. When high, this pin disables normal operation, forcing OUTA and OUTB low. 2 INA Inverting Input Pin for Channel A Gate Driver. 3 PGND Ground. This pin should be closely connected to the source of the power MOSFET. 4 INB Inverting Input Pin for Channel B Gate Driver. 5 OUTB Output Pin for Channel B Gate Driver. 6 VDD Power Supply Voltage. Bypass this pin to PGND with a ~1 µF to 5 µF ceramic capacitor. 7 OUTA Output Pin for Channel A Gate Driver. 8 OTW Overtemperature Warning Flag. Open drain, active low.
