Detailed Pin Function Descriptions

Pin 1 (VSS) - Ground for Logic Circuitry: This pin serves as the system ground and should be connected to the circuit’s ground for the operation of logic circuitry.

Pin 2 (LO) - Low-Side Driver Output: Connect to the gate of the low-side MOSFET. The low-side driver controls the gate of the MOSFET and ensures proper operation by providing necessary voltage levels for switching.

Pin 3 (VB) - Bootstrap Pin: Provides the necessary high-side gate drive voltage to the gate of the high-side MOSFET. A bootstrap capacitor (typically between 0.1uF to 1uF) is connected between this pin and the VS pin for proper high-side driver operation.

Pin 4 (VS) - High-Side Source Pin: This pin is connected to the source of the high-side MOSFET. The voltage here is floating and is referenced to the low-side driver. It ensures proper operation of the high-side MOSFET driver.

Pin 5 (HO) - High-Side Driver Output: Connect to the gate of the high-side MOSFET. The high-side driver controls the gate of the MOSFET, ensuring it operates properly at the appropriate voltage levels.

Pin 6 (VSS) - Ground for Logic: This pin serves as the ground for the logic circuitry, ensuring proper operation of the logic controls and signals.

Pin 7 (COM) - Common Pin: This pin provides a reference for both the high-side and low-side logic circuits. It should be connected to the system ground.

Pin 8 (DT) - Dead Time Control: This pin adjusts the dead-time, which is the time delay between turning off one MOSFET and turning on the other. This feature is used to prevent shoot-through in the MOSFETs, which could lead to short circuits.

Pin 9 (VCC) - Low-Side Supply: This pin powers the low-side logic circuitry, typically from a 3.3V or 5V supply depending on the requirements.

Pin 10 (IN) - Low-Side Input: This pin controls the low-side MOSFET. When a signal is applied to this pin, the low-side MOSFET is turned on or off depending on the signal level.

Pin 11 (SD) - Shutdown Pin: When a logic low signal is applied to this pin, the entire driver is disabled, causing both MOSFETs to turn off.

Pin 12 (HO) - High-Side Output: Similar to Pin 5, this pin drives the high-side MOSFET gate. It works in coordination with the VS pin to drive the MOSFET gate properly.

Pin 13 (VB) - Bootstrap Input: Connect to a capacitor to provide the necessary voltage for the high-side MOSFET drive. This pin ensures that the high-side MOSFET gets enough voltage for switching.

Pin 14 (VS) - High-Side Source Pin: This pin is directly connected to the source of the high-side MOSFET and is used to sense the floating voltage between the high-side driver and MOSFET source.

Pin 15 (VSS) - Ground for Logic: As with Pin 1 and Pin 6, this pin is used as the ground for the logic circuitry.

Pin 16 (VCC) - Low-Side Logic Supply: This pin provides the voltage for the low-side logic circuitry.
