Working Principle
- The BTS7960 integrates a high-side p-channel MOSFET and a low-side n-channel MOSFET to form a complete half-bridge for driving inductive loads
- The integrated driver accepts logic level control signals from a microcontroller and automatically manages gate timing with built-in dead time generation
- PWM control regulates motor speed while active freewheeling improves efficiency and reduces switching losses
- The integrated current sensing function provides diagnostic feedback for monitoring motor load conditions
- Protection circuits continuously monitor operating conditions and automatically shut down the device during overcurrent, short-circuit, overtemperature, overvoltage, or undervoltage events
