Overview
The DRV8837CDSGR is a low-voltage half-bridge motor driver manufactured by Texas Instruments. It features an integrated NMOS power stage capable of delivering up to 1 A continuous output current. The device operates with a load voltage range from 0 V to 11 V and a logic supply voltage between 1.8 V and 7 V. It utilizes a PWM input interface for control and includes built-in protection mechanisms such as overcurrent, short-circuit, undervoltage lockout, and thermal shutdown. The component is housed in an 8-WSON package and supports surface-mount installation.
Feature Summary
- Integrates an NMOS half-bridge power stage with internal charge pump for gate drive generation
- Supports PWM input interface compatible with standard industry control signals
- Includes comprehensive protection features including overcurrent, short-circuit, undervoltage lockout, and thermal shutdown
Applications
- Brushed DC motor control in consumer electronics
- Motion control systems in toys
- Camera module actuation
- Solenoid driving applications
Procurement Notes
Verify the specific suffix 'GR' indicates reel packaging when ordering. Confirm the 'C' variant designation matches the required electrical specifications against the official datasheet. Ensure the 8-WSON package footprint aligns with the PCB layout design. Check for any recent product change notices regarding assembly sites or material updates before finalizing procurement.
Selection Notes
Select this component for applications requiring a single H-bridge configuration with low voltage operation. It is suitable for battery-powered devices due to its low quiescent current. Consider the 1 A current limit and 11 V maximum load voltage when sizing for the target motor or load. The WSON-8 package is appropriate for space-constrained designs requiring surface-mount technology.
Part Context
The DRV8837CDSGR belongs to the DRV8837 family of low-voltage motor drivers from Texas Instruments. This series is designed for compact motion control solutions in portable and consumer applications. The device integrates the necessary power and control circuitry into a small form factor, simplifying system design for brushed DC motors and solenoids.
Replacement Considerations
Consult the official TI replacement matrix for verified substitutes. Cross-reference pinouts and electrical parameters with alternative part numbers before implementation.
