Overview
The DRV8837DSGR is a low-voltage brushed DC motor driver from Texas Instruments, housed in an 8-pin WSON package. It integrates an H-bridge of N-channel power MOSFETs with an internal charge pump for gate drive. The device supports a motor supply voltage range of 0 V to 11 V and a logic supply voltage of 1.8 V to 7 V. It delivers a continuous output current of 1.8 A. Operating temperatures span from -40°C to +85°C. The quiescent current is specified at 300 µA or 800 µA depending on the source data.
Feature Summary
- Integrates an H-bridge configuration using N-channel power MOSFETs driven by an internal charge pump.
- Supports PWM input interface compatible with standard industry control signals.
- Includes comprehensive protection features such as overcurrent protection, short-circuit protection, undervoltage lockout, and thermal shutdown.
Applications
- Camera modules
- Consumer electronics devices
- Toys
- Low-voltage battery-powered motion control systems
Procurement Notes
Verify the specific suffix against the manufacturer datasheet to confirm pinout and electrical characteristics. Ensure the component matches the required operating temperature range and voltage specifications for the target application. Confirm RoHS compliance status through official documentation before integration into production designs.
Selection Notes
Select this component for applications requiring a compact solution for single brushed DC motor control. The small form factor suits space-constrained portable devices. Verify that the load current requirements do not exceed the rated output capacity under expected thermal conditions. Consider the available evaluation module for initial circuit validation.
Part Context
This part belongs to the DRV8837 series of motor drivers designed for low-voltage applications. It is manufactured by Texas Instruments and utilizes a surface-mount WSON-8 package. The series is intended for portable and battery-operated systems where size and efficiency are critical design parameters.
Replacement Considerations
The DRV8837CDSGT is a related variant within the same family. Verify compatibility regarding package dimensions and electrical ratings when considering substitutes. Consult official substitution guides for confirmed equivalent parts.
