Overview
The MC34923EG is a full-bridge PWM motor driver designed for brushed DC motors. It integrates power MOSFETs and operates within a supply voltage range of 4.5V to 5.5V. The device supports serial interface control and delivers an output current capability of up to 2.0A with typical on-resistance of 0.6 Ohm. Operating supply current is specified at 10 mA, and the unit functions across temperatures from -20°C to 85°C.
Feature Summary
- Integrates full-bridge H-Bridge architecture with power MOSFETs
- Supports pulse-width modulated (PWM) current control
- Utilizes serial interface for command input
Applications
- Brushed DC motor drive systems
- Pulse-width modulated current control applications
- Smart drive motor control solutions
Procurement Notes
Verify component status as the MC34923EG is listed as obsolete and no longer manufactured by NXP USA Inc. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compatibility with existing system designs before procurement due to end-of-life status.
Selection Notes
Select this component only for legacy designs requiring a 2A full-bridge driver with serial interface. Consider modern replacements for new projects due to obsolescence. Verify voltage range compatibility with 4.5V to 5.5V supply rails and ensure thermal management suits the 0.6 Ohm typical resistance characteristics.
Part Context
Part of NXP's SMARTMOS technology family, the MC34923EG was designed by Motorola, Inc. It serves as a dedicated motor driver solution for industrial and consumer applications requiring robust brushed DC motor control. The device represents an integrated approach combining logic and power stages in a single package.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. As the MC34923EG is obsolete, consult NXP technical support or distributor catalogs for equivalent full-bridge motor drivers with similar current and interface specifications.
