Dual 5 A High Speed Low-Side MOSFET Drivers with Enable NCP81071 NCP81071 is a high speed dual lowside MOSFETs driver. It is capable of providing large peak currents into capacitive loads. This www.onsemi.com driver can deliver 5 A peak current at the Miller plateau region to help reduce the Miller effect during MOSFETs switching transition. This MARKING DIAGRAMS driver also provides enable functions to give users better control capability in different applications. ENA and ENB are implemented 8 on pin 1 and pin 8 which were previously unused in the industry XXXX SOIC8 ALYW standard pinout. They are internally pulled up to drivers input D SUFFIX voltage for active high logic and can be left open for standard CASE 751 1 operations. This part is available in MSOP8EP package, SOIC8 package and WDFN8 3 mm x 3 mm package.

NCP81071 Block Diagram Table 1. PIN DESCRIPTION Pin No. Symbol Description 1 ENA Enable input for the driver channel A with logic compatible threshold and hysteresis. This pin is used to en- able and disable the driver output. It is internally pulled up to VDD with a 200 k resistor for active high op- eration. The output of the pin when the device is disabled will be always low. 2 INA Input of driver channel A which has logic compatible threshold and hysteresis. If not used, this pin should be connected to either VDD or GND. It should not be left unconnected. 3 GND Common ground. This ground should be connected very closely to the source of the power MOSFET. 4 INB Input of driver channel B which has logic compatible threshold and hysteresis. If not used, this pin should be connected to either VDD or GND. It should not be left unconnected. 5 OUTB Output of driver channel B. The driver is able to provide 5 A drive current to the gate of the power MOSFET. 6 VDD Supply voltage. Use this pin to connect the input power for the driver device. 7 OUTA Output of driver channel A. The driver is able to provide 5 A drive current to the gate of the power MOSFET. 8 ENB Enable input for the driver channel B with logic compatible threshold and hysteresis. This pin is used to en- able and disable the driver output. It is internally pulled up to VDD with a 200 k resistor for active high op- eration. The output of the pin when the device is disabled will be always low. www.onsemi.com 2
