BTS7960B

BTS7960B Description

The BTS7960B from Infineon Technologies is a high-current half-bridge driver designed for inductive loads, featuring a peak output current of 60A and a continuous output current of 40A per channel. Operating within a wide supply voltage range (5.5V to 27.5V), this DMOS-based driver is part of the NovalithIC™ series, integrating advanced protection mechanisms such as current limiting, over-temperature shutdown, short-circuit protection, and undervoltage lockout (UVLO). Its low Rds(on) values (9mOhm LS, 7mOhm HS) ensure efficient power handling with minimal heat dissipation.

BTS7960B Features

• High Power Efficiency: Optimized DMOS technology reduces conduction losses, enhancing thermal performance.
• Advanced Protection: Built-in fault protection (current limiting, thermal shutdown, UVLO) ensures robust operation in harsh conditions.
• Smart Control: Features slew rate control for reduced EMI and a status flag for real-time diagnostics.
• Compact & Reliable: Surface-mount TO263-7 package with MSL 1 (Unlimited) rating, suitable for automated assembly.
• Latch Function: Ensures stable operation during transient conditions, ideal for motor control applications.

BTS7960B Applications

The BTS7960B excels in high-current DC motor drives, industrial automation systems, and general-purpose switching applications. Its high efficiency and protection features make it ideal for:

• Automotive actuators (e.g., power windows, seat adjusters).
• Robotics (motor drivers for servo/stepper systems).
• Power tools and HVAC systems requiring reliable half-bridge switching.

Conclusion of BTS7960B

While obsolete, the BTS7960B remains a benchmark for high-performance half-bridge drivers, offering exceptional current handling, integrated protection, and compact design. Its slew rate control and diagnostic capabilities provide a competitive edge for precision motor control and high-reliability systems. Engineers seeking alternatives should consider newer NovalithIC™ variants with similar specs but updated availability.
