5 Pin Configuration and Functions
Figure 5-1 D Package, 8-Pin SOIC (Top
View)Table 5-1 Pin Functions
| PIN | DESCRIPTION | |||
|---|---|---|---|---|
| NO. | NAME | TYPE(1) | ||
| 1 |
GVDD |
P | Gate driver positive supply rail. Locally decouple to ground using low ESR and ESL capacitor located as close to IC as possible. | |
| 2 |
INH |
I | High-side control input. The INH input is compatible with TTL and CMOS input thresholds. Unused INH input must be tied to ground and not left open. | |
| 3 | INL | I | Low-side control input. The inverting INL input is compatible with TTL and CMOS input thresholds. Unused INL input must be tied to GVDD and not left open. | |
| 4 |
GND |
G | Ground. All signals are referenced to this ground. | |
| 5 | GL | O | Low-side gate driver output. Connect to the gate of the low-side MOSFET or one end of external gate resistor, when used. | |
| 6 | SH | P | High-side source connection. Connect to the negative terminal of the bootstrap capacitor and to the source of the high-side MOSFET. | |
| 7 | GH | O | High-side gate driver output. Connect to the gate of the high-side MOSFET or one end of external gate resistor, when used. | |
| 8 | BST | P | High-side gate driver positive supply rail. Connect the positive terminal of the bootstrap capacitor to BST and the negative terminal of the bootstrap capacitor to SH. The bootstrap capacitor must be placed as close to IC as possible. | |
