Overview
The NCP81071ADR2G is a dual low-side MOSFET gate driver manufactured by onsemi, housed in an SOIC-8 surface-mount package. It features two independent drivers with a peak output current of 5 A and operates within a supply voltage range of 4.5 V to 20 V. The device exhibits rise and fall times of 8 ns, with maximum turn-on and turn-off delays of 35 ns. It supports a working temperature range from -40°C to +140°C and draws a typical operating supply current of 1.4 mA.
Feature Summary
- Provides high peak current capability of 5 A to mitigate Miller effect during switching transitions.
- Features TTL/CMOS compatible inputs that remain independent of the supply voltage.
- Integrates enable functionality for each driver to enhance application control.
Applications
- Synchronous rectifiers in power supplies
- DC/DC converters
- Motor drivers
Procurement Notes
Verify the specific suffix 'ADR2G' corresponds to the SOIC-8 package and standard reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input signal levels match the specified TTL/CMOS compatibility requirements for reliable operation across the defined temperature range.
Selection Notes
Select this component when a dual low-side configuration with 5 A drive strength is required in a compact SOIC-8 footprint. It serves as a direct pin-compatible replacement for many industry-standard dual MOSFET drivers while offering integrated enable controls. Consider thermal performance and PCB layout constraints associated with the SOIC-8 package for optimal heat dissipation.
Part Context
This part belongs to the NCP81071 series of high-speed dual low-side MOSFET drivers. The series includes variants with different packages such as MSOP-8, WDFN-8, and WFDN-8, all sharing similar electrical characteristics. The NCP81071ADR2G specifically denotes the SOIC-8 package variant designed for surface-mount assembly.
Replacement Considerations
Direct pin-compatible alternatives within the same family include NCP81071BZR2G (MSOP-8) and NCP81071BMNTXG (WFDN-8). Verify package dimensions and thermal pad requirements when substituting with these variants to ensure mechanical fit and thermal management adequacy.
