Overview
The NCP81071DDR2G is a dual low-side MOSFET gate driver manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 20 V and delivers a peak output current of 5 A per channel. The device features symmetric rise and fall times of 8 ns, with maximum turn-on and turn-off delays of 35 ns. It functions reliably across an extended temperature range from -40 °C to +140 °C. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Dual-channel architecture providing independent low-side drive capabilities for power switching applications
- TTL and CMOS compatible input logic levels that remain consistent regardless of the supply voltage
- High-speed switching performance characterized by 8 ns rise and fall times
Applications
- DC-DC converter circuits requiring low-side MOSFET control
- Power management modules in industrial equipment
- Automotive electronic systems utilizing silicon-based power stages
Procurement Notes
Verify the specific suffix DDR2G against official manufacturer documentation to confirm the SOIC-8 package configuration and tape-and-reel shipping format. Ensure compatibility with system voltage requirements between 4.5 V and 20 V. Cross-reference thermal specifications for operation up to 140 °C. Confirm RoHS compliance status through current datasheets before integration into production designs.
Selection Notes
Select this component when dual isolated low-side driving is required without high-side functionality. The 5 A output current supports moderate-power MOSFETs efficiently. Consider the SOIC-8 footprint for PCB layout constraints. Evaluate the 35 ns delay limits against switching frequency requirements to ensure adequate timing margins in the target application circuit.
Part Context
This part belongs to the NCP81071 series of dual low-side drivers. It shares core electrical characteristics with variants like NCP81071ADR2G but differs in packaging or reel specifications. The series targets general-purpose power management needs where cost-effective, reliable low-side switching is essential for synchronous rectification or half-bridge configurations.
Replacement Considerations
NCP81071ADR2G offers identical electrical performance in an SOIC-8 package. NCP81071AZR2G provides the same functionality in an MSOP-8 package. Verify pinout compatibility and thermal dissipation requirements when substituting these equivalents.
