Description

BTS7960 is part of the NovalithIC family containing three separate chips in one package: One p-channel highside MOSFET and one n-channel lowside MOSFET together with a driver IC, forming a fully integrated high current half-bridge.

It offers a typical 16mΩ path resistance, PWM operation up to 25kHz, adjustable slew rate, current sensing, and comprehensive protection functions including overcurrent, overtemperature, overvoltage, undervoltage, and short-circuit protection. The device is widely used in DC motor drives, H-bridge motor controllers, automotive electronics, robotics, and industrial motion control systems.

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

Design Notes

• Use adequate PCB copper area or a heatsink for high current applications to improve thermal performance
• Place low ESR bypass capacitors close to the supply pins to minimize voltage transients during PWM switching
• Adjust the slew rate when necessary to achieve the best balance between switching performance and EMI
• Monitor the diagnostic output to detect fault conditions and improve system reliability
• Combine two BTS7960 devices to implement a full H-bridge for bidirectional DC motor control

How to Choose This Part

• Select the BTS7960B for applications requiring high current half-bridge motor control with integrated protection features
