Infineon IFX1763LDVXUMA1: High-Current H-Bridge Motor Driver for Automotive Applications

The evolution of automotive systems towards greater electrification demands robust and efficient solutions for driving high-current loads, particularly motors. Addressing this need, the Infineon IFX1763LDVXUMA1 stands out as a premier fully protected H-Bridge motor driver IC engineered specifically for the rigorous demands of the automotive environment. This device integrates control logic, power stages, and comprehensive protection features into a single, compact package, providing a reliable and simplified solution for driving DC motors in a wide array of applications.

At its core, the IFX1763LDVXUMA1 is designed to deliver a continuous output current of up to 30A and handle peak currents even higher, making it suitable for demanding loads such as electric power steering (EPS) systems, hydraulic pumps, engine cooling fans, and automated actuators. Its H-Bridge configuration allows for bidirectional control of a single DC motor, enabling precise forward, reverse, and braking operations through a simple input interface. The driver operates from a typical automotive battery voltage range of 5.5 V to 28 V, comfortably handling load-dump conditions.

A key strength of this driver is its integrated suite of protection and diagnostic features, which is critical for functional safety and system longevity. These include:

Over-current Protection (OCP): Safely limits the output current during short circuits or stall conditions.

Over-temperature Protection (OTP): Shuts down the device if the junction temperature exceeds safe limits.

Under-voltage Lockout (UVLO): Disables the output when the supply voltage is too low for proper operation.

Over-voltage Protection (OVP): Protects the IC from voltage transients.

Open-load Detection: Identifies disconnected motor phases.

The device is offered in a thermally enhanced, surface-mount DSO-28 package that ensures efficient heat dissipation, which is paramount for maintaining performance under high-current conditions. Its design complies with AEC-Q100 automotive qualification standards, guaranteeing reliability and performance across the extreme temperature ranges and harsh conditions typical of automotive applications.

ICGOOODFIND: The Infineon IFX1763LDVXUMA1 is a high-performance, highly integrated H-Bridge motor driver that offers superior power handling, robust protection, and diagnostic capabilities. It significantly simplifies design-in for automotive engineers, reducing system complexity and board space while enhancing overall reliability for critical 12V and 24V motor control systems.
