BTS7960 Motor Driver

• Dual BTS7960 H-Bridge DC Motor Driver max. 43A
• The BTS7960 motor driver will control one motor.
• It requires a drive power supply of 6-27V DC, a logic supply voltage of +5V, and one or two logic level PWM inputs to control rotational speed and direction.

The BTS7960 can operate in three different way, depending on wiring and controls:

1. Fixed Speed Operation

• This will allow the motor to operate full speed forward or reverse.
• Connect terminal 1 to Ground and terminal 2 to Positive of a 6-27 V power supply
• Connect terminals 3 and 4 to motor positive and negative, respectively
• Connect logic pin A to ground and pins B, E and F to a +5V power supply
• For forward rotation, connect pin H to +5V power supply. For reverse rotation, connect pin G to +5V power supply. This will operate the motor at full speed either forward or reverse.

    2. Variable Speed Operation

(Speed proportional to PWM on PIN H/PIN G. Better for slower speeds but requires two PWM signals, one for Forward and the other for Reverse)

• Connect terminal 1 to Ground and terminal 2 to Positive of a 6-27 V power supply
• Connect terminals 3 and 4 to motor positive and negative, respectively
• Connect logic pin A to ground and pin B +5V power supply
• Connect remaining pins as shown in tables below

    3.Variable Speed Operation
(Speed proportional to PWM on PINS E + F. Use one PWM signal and send to both E and F. Requires only one PWM signal however there is significant power loss and shorter motor RPM range)

 

1. Fixed Speed Operation

PIN H	PIN G	PINS E + F	Motor Output
5 volts	0 volts	5 volts	Full speed Forward
0 volts	5 volts	5 volts	Full speed Reverse

 

  2. Variable Speed Operation

PWM signals, one for Forward and the other for Reverse) PIN H	PIN G	PINS E + F	Motor Output
PWM (500 Hz, 5V amplitude)	0 volts	5 volts	Variable speed Forward
0 volts	PWM (500 Hz, 5V amplitude)	5 volts	Variable speed Reverse

 

3.Variable Speed Operation

PIN H	PIN G	PINS E + F	Motor Output
5 volts	0 volts	PWM (500 Hz, 5V amplitude)	Variable speed Forward
0 volts	5 volts	PWM (500 Hz, 5V amplitude)	Variable speed Reverse
