MC33926AESR2

Overview

The MC33926AESR2 is a SMARTMOS monolithic H-bridge power chip designed for automotive applications. It operates within a 5V to 28V supply voltage range and delivers a continuous output current of 5A. The device features an internal constant off-time PWM for overcurrent limiting, output short-circuit protection, and temperature-dependent current limit threshold reduction. It is qualified to AEC-Q100 Grade 1 standards and supports a 20 kHz PWM frequency. The component is housed in a HVQFN-28 (6x6 mm) package with SMD/SMT mounting style.

Feature Summary

• Monolithic H-bridge architecture with integrated SMARTMOS technology
• Internal constant off-time PWM for regulated overcurrent limiting
• Output short-circuit protection against VPWR or ground faults
• Temperature-dependent current limit threshold reduction

Applications

• Automotive electronic throttle control
• Exhaust gas recirculation (EGR) systems
• Turbocharger flap control
• Low-voltage DC servo motor control

Procurement Notes

Verify the specific suffix 'AESR2' against official NXP documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure compatibility with AEC-Q100 Grade 1 requirements for your target automotive application. Cross-reference the HVQFN-28 footprint dimensions during PCB layout finalization to prevent mechanical interference.

Selection Notes

Select this component for brushed DC motor drivers requiring robust overcurrent protection and thermal management. The 5A current rating and 28V maximum supply voltage suit most automotive low-voltage motor applications. Consider the HVQFN-28 package size if board space is constrained. Verify that the 20 kHz operating frequency aligns with your system's noise and efficiency requirements.
