Instructions for Use:
Power Supply Connections:
- Connect the high-side supply voltage (VHB) to the appropriate pin.
- Connect the low-side supply voltage (VSB) to the appropriate pin.
- Ensure the floating supply voltage (VBS) is within the specified range.
Gate Drive Outputs:
- The gate drive outputs (HO and LO) should be connected to the gates of the high-side and low-side MOSFETs, respectively.
- Ensure the gate drive voltages (VGH and VGL) are within the specified limits to avoid damage to the MOSFETs.
Input Signals:
- Apply the input signals (IN) to control the switching of the high-side and low-side MOSFETs.
- Ensure the input signals are compatible with the propagation delay and rise/fall times to maintain proper operation.
Under-Voltage Lockout (UVLO):
- The device includes under-voltage lockout protection. If the supply voltage falls below the UVLO threshold, the device will shut down to prevent damage.
- Monitor the supply voltages to ensure they remain above the UVLO threshold during operation.
Thermal Management:
- Ensure adequate heat dissipation to keep the operating temperature within the specified range.
- Consider using a heatsink or other cooling methods if operating at high temperatures.
Short-Circuit Protection:
- The device has built-in short-circuit protection. However, it is recommended to implement additional external protection circuits to enhance reliability.
Storage and Handling:
- Store the device in a dry, cool environment within the specified storage temperature range.
- Handle the device with care to avoid static discharge and physical damage.
Schematic and Layout:
- Refer to the datasheet for recommended schematic and PCB layout guidelines to ensure optimal performance and reliability.
