VNH3SP30-E

Overview

The VNH3SP30-E is a fully integrated H-bridge motor driver designed for automotive applications. It incorporates a dual monolithic high-side driver and two low-side switches, utilizing VIPower M0-3 technology for the high-side and STripFET process for the low-side MOSFETs. The device supports an output current of 30 A with a supply voltage range of 5.5 V to 36 V. It operates within a temperature range of -40°C to +150°C and features PWM control up to 10 kHz. The component is housed in a MultiPowerSO-30 package and holds AEC-Q100 qualification.

Feature Summary

• Integrates dual monolithic high-side drivers and low-side switches on isolated lead frames for improved thermal performance
• Provides direct microcontroller interface compatibility via 5 V logic level inputs
• Includes comprehensive protection mechanisms such as thermal shutdown, cross-conduction protection, and overvoltage clamp
• Offers digital diagnostic feedback through dedicated enable/diagnostic pins

Applications

• Automotive brushed DC motor control systems
• Vehicle window and seat adjustment actuators
• HVAC fan and blower motor drives
• Wiper and washer pump controllers

Procurement Notes

Verify that the specific order suffix matches the required packaging format, such as reel or cut tape, as indicated in official distributor catalogs. Confirm AEC-Q100 qualification status is explicitly stated for the target automotive application requirements. Ensure the MultiPowerSO-30 package variant aligns with the printed circuit board footprint specifications. Check for any recent product change notifications regarding manufacturing site transitions.

Selection Notes

Select this component when a robust, single-chip solution for high-current brushed DC motors is required in automotive environments. The integrated VIPower technology simplifies design by combining power stages with intelligent protection circuits. Consider the thermal performance of the exposed die pads in the MultiPowerSO-30 package for heat dissipation needs. Verify that the 30 A continuous current rating meets the peak and steady-state demands of the specific motor load.
