VNH3SP30TR-E

Overview

The VNH3SP30TR-E is a fully integrated automotive H-bridge motor driver designed for high-power applications. It incorporates a dual monolithic high-side driver and two low-side switches within a MultiPowerSO-30 package. The device supports an output current of 30 A and operates with a supply voltage range from 5.5 V to 36 V, with a maximum collector-emitter voltage of 40 V. It features 5 V logic level compatible inputs and PWM operation up to 10 kHz. The component is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +150°C.

Feature Summary

• Integrates dual high-side drivers and low-side switches using VIPower M0-3 technology for efficient signal and protection circuit integration on the same die.
• Provides digital diagnostic feedback via DIAG pins when connected to external pull-up resistors, enabling leg enablement and status monitoring.
• Includes comprehensive protection mechanisms such as thermal shutdown, overvoltage clamp, cross-conduction protection, and linear current limiting.

Applications

• Automotive window lifters
• Seat positioning actuators
• Brushed DC motor controllers

Procurement Notes

Verify that the specific part number suffix matches the required reel or cut tape configuration, as packaging options vary. Confirm AEC-Q100 qualification status is required for the target automotive application. Ensure the MultiPowerSO-30 package thermal pads are properly soldered to the PCB ground plane to maintain specified thermal performance and reliability in harsh environments.

Selection Notes

Select this component for applications requiring a single-chip solution for brushed DC motors with high current demands. The 30 A output capability suits heavy-duty actuator control. Consider the 10 kHz PWM limit when designing control loops. The symmetrical mechanical design facilitates board-level manufacturability. Verify input signal compatibility with the host microcontroller's voltage levels before integration.

Part Context

This device belongs to the VNH3SP30-E series, which represents STMicroelectronics' dedicated full-bridge motor drivers for automotive use. The series utilizes proprietary EHD (STripFET) process for low-side switches and VIPower technology for high-side integration. The MultiPowerSO-30 package is specifically engineered for improved thermal dissipation and robustness in automotive electrical systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official STMicroelectronics resources for potential pin-compatible alternatives or updated series members if sourcing constraints exist.

FAQ

How is the motor direction controlled?

Motor direction is selected by interfacing the INA and INB input signals directly with the microcontroller, which determines the state of the internal switches.

What happens during a low level state on the PWM pin?

A low level state on the PWM pin turns off both the LSA and LSB switches, effectively braking or stopping the motor depending on the bridge configuration.
