Overview
The NCP81071CDR2G is a dual low-side MOSFET gate driver manufactured by onsemi. It features two independent drivers with peak output currents of 5 A for both sourcing and sinking. The device operates within a supply voltage range of 4.5 V to 20 V. Typical rise and fall times are specified at 8 ns each. The component supports an operating junction temperature range from -40 °C to +140 °C. It is housed in an SOIC-8 surface-mount package.
Feature Summary
- Provides high current driving capability of plus or minus 5 A to handle capacitive loads and reduce Miller effect during switching.
- Features TTL and CMOS compatible inputs that remain independent of the supply voltage for easy implementation.
- Includes integrated enable functionality for each driver to allow precise control over application timing.
Applications
- Synchronous rectifiers in power conversion circuits
- DC/DC converters for server and telecom power supplies
- Motor drivers in industrial and automotive systems
Procurement Notes
Verify the specific suffix CDR2G corresponds to the SOIC-8 package variant when ordering. 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 full temperature range.
Selection Notes
Select this component for applications requiring fast switching speeds with moderate drive current. The dual channel configuration allows for parallel connection to increase drive strength if necessary. Consider the SOIC-8 footprint constraints against available PCB space. Validate thermal performance under maximum load conditions given the wide operating temperature specification.
Part Context
This part belongs to the NCP81071 series of high-speed dual low-side MOSFET drivers. The series offers pin-compatible alternatives in various packages including MSOP-8, WDFN-8, and DFN-8. All variants share similar electrical characteristics but differ in physical dimensions and thermal dissipation properties.
Replacement Considerations
Direct substitutes include other NCP81071 variants such as NCP81071AZR2G or NCP81071BZR2G which offer identical electrical specifications in different package formats like MSOP-8.
