Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module

The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module is a robust driver designed for high-current H-bridge motor drive applications. It utilizes the BTS7960 high-current half-bridge, which integrates a p-channel high-side MOSFET and an n-channel low-side MOSFET in a single package along with an integrated driver IC. This configuration eliminates the need for a charge pump, reducing EMI and simplifying the design.

  Key Features:  

• PWM capability of up to 25 kHz with active freewheeling.
• Switched-mode current limitation for reduced power dissipation during overcurrent conditions.elec
• Status flag diagnosis with current sensing capability.
• Overtemperature shutdown with latch behavior.
• Overvoltage lockout and undervoltage shutdown.
• Driver circuit with logic level inputs.
• Adjustable slew rates for optimized EMI.
• 74AHC244 Schmitt-trigger octal buffer/line driver for ESD protection (inputs accept voltages higher than VCC).
