Product description: TB6612FNG - 2-channel motor controller

Two channel H-bridge. Continuous current per channel 1,2 A momentary up to 3,2 A. Supply voltage up to 15 V. Housing SSOP-24 (SMD).

Controller's specification

  • Maximum supply voltage for motors: from 4.5 to 15 V
  • Continuous current 1,2 A
  • Instantaneous current: 3,2 A
  • Low current mode (Standby)
  • Possibility of changing the direction of rotation of the motor
  • Quick stop of the motor
  • Housing: SMD SSOP24
  • Controller channels can be combined to obtain higher current capacity
