Smart Driver IC Supports Battery-Powered DC Motors

By Mat Dirjish

Trinamic introduces the TMC7300, a smart driver IC for battery-powered dc motors. The device drives one or two dc motors and employs UART-based control for torque and velocity. It acts as a low-voltage driver for one dc motor up to 2A peak, or two dc motors up to 2.4A peak on a single or dual Li-Ion cell or at least 2 AA batteries.

Available in a 20-pin, 3 mm x 3 mm QFN package, the TMC7300 offers high power density via integrated power MOSFETs and dc- motor control logic. Features include:

  • Voltage range of 1.8 to 11 Vdc
  • Single-wire UART with velocity control, torque control, and direction
  • Standby current draw of less than 50 nA typical
  • Low on resistance (RDSon) with LS 170 mΩ and HS 170 mΩ (typical)
  • Full protection and diagnostics, including motor load feedback
  • PWM control of LEDs

The TMC7300-LA motor driver, along with the TMC7300-BOB breakout board and the TMC7300-EVAL evaluation board, will be available at the end of January. For more deeper details, checkout the TMC7300-LA datasheet.
