NCP81071AZR2G

Overview

The NCP81071AZR2G is a dual low-side MOSFET gate driver manufactured by onsemi, designed for high-speed switching applications. It features two independent drivers with a peak output current of 5 A per channel. The device operates within a supply voltage range of 4.5 V to 20 V and supports TTL/CMOS compatible inputs. Key timing parameters include rise and fall times of 8 ns each. It is housed in an MSOP-8 surface-mount package with an exposed pad for thermal management. The component functions reliably across an extended temperature range from -40 °C to +140 °C.

Feature Summary

• Provides high-current driving capability of +/- 5 A to manage capacitive loads and mitigate Miller effect during switching transitions.
• Integrates individual enable functionality for each driver channel, allowing precise control over application operation.
• Features TTL and CMOS compatible input logic levels that remain consistent regardless of the supply voltage.
• Maintains pin compatibility with popular industry-standard dual MOSFET drivers to facilitate direct replacements.

Applications

• Synchronous rectifiers in DC/DC converters
• Power factor correction circuits
• Motor drivers
• Telecom and server power supplies

Procurement Notes

Verify the specific suffix 'AZR2G' corresponds to the MSOP-8 package variant when sourcing. Confirm RoHS compliance status through official documentation as required by project specifications. Ensure the ordering quantity aligns with standard reel or cut-tape availability constraints. Cross-reference the manufacturer part number against distributor catalogs to avoid confusion with other package options like WDFN-8 or SOIC-8 within the same series.

Selection Notes

Select this component when a dual low-side driver with 5 A output current is required for space-constrained designs utilizing MSOP-8 packaging. It is suitable for applications needing independent channel enablement and fast switching speeds around 8 ns. Consider alternative packages such as WDFN-8 if higher thermal dissipation or different footprint dimensions are necessary for the PCB layout.

Part Context

This part belongs to the NCP81071 series of high-speed dual low-side MOSFET drivers. The series includes variants with different package types, such as NCP81071AMNTXG (WDFN-8) and NCP81071BMNTXG (WDFN-8), offering flexibility in thermal and mechanical design. All members share identical electrical characteristics but differ in physical housing and mounting style.

Replacement Considerations

Direct pin-compatible substitutes within the same series include NCP81071AMNTXG and NCP81071BMNTXG, though these utilize WDFN-8 packages requiring PCB layout adjustments. Single-channel equivalents like NCP81074BDR2G offer 10 A drive current but lack dual-channel functionality.
