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
We also offer a module with TB6612 driver. The chip has holes for goldpin connectors (2.54 mm pitch), which allow to plug it into contact board or connect it by wires.
