Overview
The DRV8214RTER is a half-bridge motor driver from Texas Instruments designed for low-voltage applications. It features an integrated N-channel power stage capable of delivering up to 4A peak output current. The device supports a supply voltage range of 1.65V to 11V and includes built-in charge pump technology for gate drive enhancement. Key protection mechanisms include over-current protection, thermal shutdown, and under-voltage lockout. The component is housed in a WSON-8 package and operates within a temperature range of -40°C to 125°C.
Feature Summary
- Integrated N-channel half-bridge with high peak current capability
- Built-in charge pump architecture for efficient gate driving
- Comprehensive protection against over-current and thermal overload
Applications
- Camera lens actuator control
- Vibration motor drivers
- Small DC motor control in portable devices
Procurement Notes
Verify the specific suffix 'RTER' corresponds to the reel packaging configuration as defined by the manufacturer. Confirm that the ordering part number matches the exact electrical specifications required for the target application. Ensure compatibility with the intended PCB footprint and thermal management requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact solution for driving small loads at low voltages. Consider the integrated protection features for robust operation in consumer electronics. Evaluate the thermal performance within the WSON-8 package against the expected duty cycle and ambient conditions of the design.
Part Context
This part belongs to the DRV821x series of low-voltage motor drivers from Texas Instruments. The series is optimized for battery-powered devices and camera modules. The DRV8214 variant specifically provides a single half-bridge configuration, distinguishing it from dual-bridge counterparts in the same family.
