VNH5180A-E

Overview

The VNH5180A-E is an automotive full-bridge motor driver designed for a wide range of applications. It incorporates a dual monolithic high-side driver and two low-side switches built using VIPower®M0 technology. The device operates with a supply voltage range of 5.5 V to 18 V and delivers an output current of 8 A. It features 3 V CMOS compatible inputs, PWM operation up to 20 KHz, and a current sense output proportional to motor current. The component is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +150°C TJ.

Feature Summary

• Integrates dual monolithic high-side drivers and low-side switches using proprietary VIPower®M0 technology for efficient on-die integration of power MOSFETs and intelligent protection circuitry.
• Provides comprehensive protection mechanisms including undervoltage shutdown, overvoltage clamp, thermal shutdown, cross-conduction protection, and current/power limitation.
• Features fully symmetrical mechanical design in PowerSSO-36 TP package with exposed die pads for improved thermal performance and superior manufacturability in harsh automotive environments.

Applications

• Automotive brushed DC motor control
• Fan and blower speed regulation
• Valve actuation systems

Procurement Notes

Verify the specific ordering suffix (e.g., 'A' for tube or 'TR' for tape and reel) as it determines the physical packaging format. Confirm the active status of the part number, as availability may vary by region or distributor. Ensure compatibility with the target microcontroller interface levels before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a single-chip solution for brushed DC motors with integrated diagnostic feedback. The 8 A continuous current rating suits moderate load requirements. Consider the PowerSSO-36 TP package for its thermal advantages if board space allows. Verify that the system ground and VCC loss protections align with the specific safety requirements of the target application.

Part Context

The VNH5180A-E belongs to the STMicroelectronics VNH51xxxA-E series of automotive H-bridge drivers. This family utilizes VIPower® technology to combine power stages with intelligent signal processing. The device is distinct from higher-current variants like the VNH5050A-E, offering a balance of performance and integration for standard automotive loads.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct pin-compatible alternatives within the same VIPower® family or consult manufacturer obsolescence notices for recommended upgrades.

FAQ

How is the motor current monitored?

The CS pin provides a current sense output proportional to the motor current when the CS_DIS pin is driven low or left open. If CS_DIS is driven high, the CS pin enters a high impedance condition.

What is the maximum PWM frequency supported?

The device supports PWM operation up to 20 KHz to control motor speed in all possible conditions.

How are the bridge legs enabled?

Each DIAGA/ENA or DIAGB/ENB pin enables one leg of the bridge when connected to an external pull-up resistor. These pins also provide a feedback digital diagnostic signal.
