Overview
The NCV7520MWTXG is a six-channel low-side MOSFET gate driver designed for automotive applications. It operates with a supply voltage range of 4.75 V to 5.25 V and delivers an output current of 26.5 mA per channel. The device features rise and fall times of 277 ns, with a maximum propagation delay of 2 µs. It is housed in a QFN-32 package and supports operating temperatures from -40°C to +150°C. Certified under AEC-Q100, it includes frame error detection and an open-drain fault flag.
Feature Summary
- Six independent low-side driver channels for simultaneous control
- Integrated frame error detection for signal integrity
- Open-drain fault flag output for status monitoring
Applications
- Automotive power distribution systems
- Low-side switching for automotive loads
- Electronic control units requiring isolated gate drive
Procurement Notes
Verify the specific suffix 'TXG' against the manufacturer's official datasheet to confirm the exact reel quantity and tape-and-reel specifications. Ensure the component meets AEC-Q100 grade requirements for your target automotive application. Cross-reference the QFN-32 package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a 5V logic interface is required for driving multiple low-side MOSFETs in automotive environments. The narrow supply voltage range indicates suitability for regulated 5V domains rather than direct battery connection. Consider the 26.5 mA output current capability relative to the total gate charge of the intended load devices to ensure adequate switching speeds within the specified temperature range.
Part Context
This part belongs to the NCV7520 series of automotive-grade gate drivers. It is distinct from higher-voltage variants like the NCV7520MWTXG-25721, which supports up to 36V. The standard NCV7520MWTXG is optimized for low-voltage logic-level applications, differentiating it from high-side or mixed-voltage driver families.
Replacement Considerations
The NCV7520FPR2G is a pin-compatible alternative in a 32-TQFP package. Verify that the thermal performance and pinout mapping are identical before substitution. Note that availability status may differ between the QFN and TQFP packages.
