Overview
The DRV8837DSGT is a low-voltage H-bridge motor driver manufactured by Texas Instruments, housed in an 8-pin WSON (2x2 mm) surface-mount package. It supports a supply voltage range of 1.8 V to 11 V and delivers a continuous output current of 1.8 A. The device features an on-resistance of 280 mΩ and operates within a temperature range of -40°C to +85°C ambient. It includes integrated control logic with PWM interface capability and offers ultra-low power consumption in sleep mode.
Feature Summary
- Compact 2x2 mm WSON-8 package for space-constrained designs
- Low on-resistance supporting high efficiency and thermal performance
- Integrated full-bridge driver with PWM control interface
- Ultra-low sleep current for extended battery life
Applications
- Portable medical devices
- Robotics systems
- Vibration motors
- Small DC motors
- Solenoid drivers
Procurement Notes
Verify the specific suffix 'DSGT' against the manufacturer's latest datasheet to confirm availability status, as this variant may be obsolete or superseded. Ensure the ordering part number matches the required tape-and-reel packaging configuration. Cross-reference the pinout and electrical specifications with the official TI documentation before finalizing procurement to avoid integration errors.
Selection Notes
Select this component for applications requiring a small footprint and low-voltage operation up to 11 V. It is suitable for driving brushed DC motors where space is limited. Consider the 1.8 A current limit and thermal dissipation requirements when designing the PCB layout. Verify compatibility with the system's control logic levels and operating temperature range.
Part Context
The DRV8837 series comprises low-voltage H-bridge drivers designed for portable applications. The DRV8837DSGT specifically denotes the tape-and-reel version of the DRV8837 device. This family is characterized by its small size and low power consumption, making it ideal for battery-powered devices such as handheld electronics and wearable technology.
Replacement Considerations
Check for direct substitutes like the DRV8838 if higher temperature ratings are needed. Verify pin-to-pin compatibility and electrical parameters before replacing. Consult the manufacturer's obsolescence notices for updated recommendations.
