Ghi chú thiết kế
The VND7140AJTR in PowerSSO-16 package requires proper thermal management. The exposed pad must be soldered to a large copper area on the PCB to dissipate heat effectively. For continuous operation at 8A per channel, ensure the PCB copper area is at least 1 square inch to keep the junction temperature within safe limits. Refer to the STMicroelectronics application note for thermal design guidelines.
Place the VND7140AJTR close to the load to minimize trace inductance and resistance. Use wide traces for the output and supply pins to handle high currents. Add a 100nF ceramic capacitor close to the VCC pin for decoupling. The MultiSense pin should be connected to an ADC input with a low-pass filter to reduce noise.
Do not exceed the maximum supply voltage of 28V. Ensure the input pins are not left floating; use pull-down resistors to keep them in a defined state. The FaultRST pin must be properly configured to avoid unintended latch-off behavior. When using the MultiSense feedback, account for the proportional current mirror ratio and calibrate the ADC readings for accurate current measurement.
