The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module is; a fully integrated high current H bridge for motor drive applications using the BTS7960 high current half bridge. the BTS7960 is part of the NovalithICTM family. This containing one p-channel high side MOSFET and one n-channel low side MOSFET; with an integrated driver IC in one package. Due to the p-channel high side switch; the need for a charge pump is eliminated thus minimizing EMI.
Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs; diagnosis with current sense, slew rate adjustment; dead time generation and protection against overtemperature, overvoltage, under voltage; overcurrent, and short circuit.
The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module provides; a cost-optimized solution for protected high current PWM motor drives with very low board space consumption.
Features :
- PWM capability of up to 25 kHz combined with active freewheeling.
- Switched mode current limitation for reduced power dissipation in overcurrent.
- Status flag diagnosis with current sense capability.
- Overtemperature shut down with latch behavior.
- Overvoltage lockout.
- Undervoltage shut down.
- Driver circuit with logic level inputs.
- Adjustable slew rates for optimized EMI.
- 74AHC244 Schmitt-trigger Octal buffer/line driver for ESD protection (Inputs accepts voltages higher than VCC).
Input port:
- RPWM: forward level or PWM signal input, active high.
