Overview
The DRV8847RTER is a dual half-bridge motor driver manufactured by Texas Instruments, designed for stepper and DC motor control applications. It operates within a supply voltage range of 2.7 V to 18 V and delivers an output current of 2 A per channel. The device features a 5 V regulator output and supports PWM frequencies up to 400 kHz. It is housed in a WQFN-16 surface-mount package and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Dual half-bridge architecture enabling independent control of two motor channels or one bipolar stepper motor.
- Integrated 5 V linear regulator provides auxiliary power for external logic or sensors.
- Wide operating voltage range accommodates various power supply configurations from 2.7 V to 18 V.
- High thermal performance allows operation at elevated ambient temperatures up to 125°C.
Applications
- Stepper motor drivers in industrial automation equipment
- DC motor control in home appliances
- Motion control systems requiring dual-channel drive capability
Procurement Notes
Verify the specific suffix 'RTER' corresponds to the WQFN-16 package and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the intended application voltage does not exceed the 18 V maximum rating. Check for any recent lifecycle notices regarding obsolescence or recommended replacements.
Selection Notes
Select this component when dual independent half-bridge outputs are required in a compact form factor. The WQFN-16 package suits space-constrained designs. Consider the 2 A continuous current limit and thermal dissipation requirements for the specific PCB layout. Verify compatibility with the system's logic voltage levels given the integrated 5 V regulator.
Part Context
The DRV8847RTER belongs to the DRV8847 series of motor drivers from Texas Instruments. This series includes variants with different packages such as TSSOP-16 (DRV8847SPWR) and HTSSOP-16 (DRV8847PWPR). All variants share similar electrical characteristics but differ in physical footprint and thermal properties.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Texas Instruments documentation for potential pin-compatible alternatives or functional equivalents within the same product family.
