Overview
The MC34933EP is a dual half-bridge gate driver IC designed for low-voltage motor control applications. It integrates internal control logic, a charge pump, and high-current MOSFET output stages with an RDS(on) of 800 mOhms. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports non-inverting configurations. It features two independent outputs capable of delivering up to 1.4 A each. The component is qualified under AEC-Q100 standards and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates internal control logic and charge pump for efficient gate drive management
- Features high-current, low on-resistance MOSFET output circuitry
- Supports driving single two-phase stepper motors or dual brushed DC motors
Applications
- Two-phase stepper motor control systems
- Dual brushed DC motor drives
- Low-voltage automotive motor applications
Procurement Notes
Verify the specific suffix EP against official NXP documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status as end-of-life products may require alternative sourcing strategies. Ensure compatibility with system voltage requirements before procurement.
Selection Notes
Select this component for applications requiring integrated half-bridge drivers in a compact form factor. The built-in charge pump simplifies design by eliminating external bootstrap components. Verify that the 5.5 V maximum supply voltage aligns with the target power rail constraints.
Part Context
This part belongs to NXP's portfolio of half-bridge drivers intended for motor control. It is often evaluated using dedicated hardware such as the FRDM-34933EP-EVB Freedom Evaluation Board. The device serves as a companion to microcontrollers for managing power stage switching in electrically driven systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official NXP documentation for recommended alternatives if this component is discontinued.
