VND5004A Dual 4mΩ High-Side Driver IC – High-Current Stepper Motor Drive Module for Automotive Body Electronics

The VND5004A is a dual-channel high-side driver IC engineered specifically for demanding automotive power distribution and motor control applications.

It is built using advanced VIPower technology, delivering extremely low on-state resistance of just 4mΩ per channel for exceptional power efficiency.

This driver module is designed to drive a wide range of loads, including resistive, inductive, and capacitive types commonly found in automotive systems.

It supports an operating voltage range from 4.5V to 27V, with the ability to withstand transient supply voltages up to 41V for robust load dump protection.

The device integrates an analog current sense feature that delivers a current proportional to the load current, enabling precise monitoring and diagnostics.

A dedicated current sense disable pin allows the sensing function to be switched off when not required, reducing system power consumption.

Inrush current is actively managed through a power limitation function, protecting both the IC and connected loads during startup.

The module offers comprehensive protection features, including undervoltage shutdown, overvoltage clamp, load current limitation, and thermal shutdown.

Fast thermal transients are self-limited, and the device includes protection against loss of ground and loss of VCC for enhanced system reliability.

Reverse battery protection is implemented through self-switch-on of the PowerMOS, eliminating the need for external protection diodes.

The VND5004A is AEC-Q100 qualified, ensuring it meets the stringent reliability and quality standards required for automotive applications.

It is particularly suitable for driving stepper motors in body control systems, such as HVAC actuators, headlight positioning, and valve controls.

With its compact surface-mount package, this IC enables space-efficient PCB designs without compromising thermal performance or current handling capability.
