The BTS7960 is a high-current H-bridge module with complete integration for motor driving applications. The integrated driver IC makes it simple to connect to a microcontroller, with logic level inputs, current sensing diagnostics, slew rate adjustment, dead time generation, and protection against overtemperature, overvoltage, under-voltage, overcurrent, and short circuit. The BTS7960 is a cost-effective option for protected high current PWM motor drives with very low board space consumption.
This package has one p-channel high-side MOSFET and one n-channel low-side MOSFET, as well as an integrated driver IC. Because the p-channel high side switch eliminates the requirement for a charge pump, EMI is reduced.

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 behaviour.
• 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.
• LPWM: Reverse level or PWM signal input, active high.
• R_EN: forward drive enable input, high-level enable, low level OFF.
