MC33926
Overview
The MC33926 is a monolithic H-bridge power IC designed for medium-current DC motor control applications, capable of handling continuous currents up to 5A. It operates over a wide voltage range from 5V to 28V and is AEC-Q100 Grade 1 qualified for demanding automotive and industrial environments. The device integrates control, protection, and diagnostic features including overcurrent, undervoltage, and overtemperature monitoring.
Why Choose This Part
The MC33926 features a temperature-dependent current limit threshold reduction that prevents catastrophic failure by scaling back performance before reaching thermal shutdown. It offers low power consumption with a 50uA sleep mode current and provides flexible control through both PWM and SPI interfaces.
Applications
Getting Started
Engineers should evaluate the thermal requirements of the PQFN package, ensuring adequate copper area for the exposed pad to handle 5A loads. To begin development, look for the FRDM-33926-EVB evaluation board which is compatible with the Freedom development platform and provides access to all control pins and diagnostic outputs.
