Controller pinouts

Sterownik silników TB67H420FTG

PIN Description
Vin Motor supply voltage from 10 V to 47 V. It has protection against polarity change of supply voltage (up to 40 V).
GND System ground potential.
VM Output to provide power to the motor after reverse polarity protection. It can be used to power other components of the system.
A+ Motor outputs A. To be connected for single channel mode.
A-
B+ B motor outputs. To be connected for single channel mode.
B-
VCC Adjustable 5 volt output. This pin gives access to the voltage from the TB67H420FTG internal regulator. The output should only be used for logic inputs as it can only provide a few milliamps.
INA1

Control input forA+.PWM can be applied to this pin (usually PWMA in the high state). Default state is low.

In single channel mode it controlsA+andA-.

INA2

Control input forA-.PWM can be applied to this pin (usually PWMA in the high state). Default state is low.

In single channel mode, controlsB+andB-.

PWMA

PWM input for channelA. Default state low.

In single channel mode, the PWM input.

INB1 Control input forB+.PWM can be applied to this pin (usually PWMB in high state). Default state is low.
INB2 Control input forB-..PWM can be applied to this pin (usually PWMB in the high state). Default state is low.
PWMB PWM input for channelB. Default state low.
LO1

Error diagnostics output. Goes low when an error occurs due to excessive current or temperature.

Default state is high.

LO2 Error diagnostics output. Goes low when load or temperature fault occurs. Default is low.
VREFA The output indicates the current threshold value for channelA.In single channel mode, outputs the current threshold value.
VREFB The output indicates the current threshold value for channelB.
TBLKAB Noise filter configuration pin for the constant current circuit. Default is low. Input should not be changed when the controller is powered.
HBMODE Operating mode configuration input, High state for single channel mode, low state for dual channel trub.This input should not be changed when the controller is powered.
