MC33926ESR2

Overview

The MC33926ESR2 is a SMARTMOS monolithic H-bridge power IC designed for automotive and industrial applications. It operates within a supply voltage range of 5V to 28V and supports a continuous output current of 5A. The device features an internal constant off-time PWM controller with overcurrent limiting and output short-circuit protection. It includes temperature-dependent current limit threshold reduction and internal source/sink resistors on all inputs to define default floating states. The component is qualified to AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Monolithic H-bridge architecture utilizing SMARTMOS technology for integrated power switching
• Internal constant off-time PWM control with adjustable overcurrent limiting
• Comprehensive protection including output short-circuit detection and thermal derating
• Defined default input states via internal source/sink resistors for robust operation

Applications

• Automotive electronic throttle control systems
• Exhaust gas recirculation (EGR) valve actuation
• Turbocharger vane or flap control mechanisms
• Industrial and medical pump motor control

Procurement Notes

Verify the specific suffix 'ESR2' against official NXP documentation to confirm package type, tape-and-reel specifications, and regional availability status. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability. Confirm compliance with RoHS directives and AEC-Q100 qualification requirements relevant to your target application environment before finalizing procurement orders.

Selection Notes

Select this component for brushed DC motor applications requiring integrated H-bridge control without external gate drivers. Ensure the system design accommodates the 5V to 28V operating voltage range and 5A current capability. Verify that the PQFN-32 package footprint aligns with PCB layout constraints. Consider the internal PWM frequency characteristics and thermal management requirements for sustained operation in high-temperature environments.

Part Context

The MC33926 belongs to NXP's portfolio of motor and motion controllers, specifically targeting automotive powertrain and emissions control actuators. It complements other NXP solutions like the HB2001 and MC33932 by offering a cost-effective, single-chip H-bridge solution. This series is designed to simplify system architecture by integrating control logic and power stages into a compact form factor suitable for space-constrained automotive modules.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative NXP H-bridge drivers such as the MC33932 or HB2001 based on functional compatibility, pinout alignment, and electrical parameter matching. Consult official NXP cross-reference guides for verified replacements.
