BTN7970B,High-Current Half-Bridge Motor Driver,PG-TO263-7-1

The BTN7970B is a high-performance half-bridge motor driver designed for automotive and industrial motor control applications. Part of the NovalithIC™ family, this device combines a P-channel high-side MOSFET, an N-channel low-side MOSFET, and an integrated driver IC, providing a robust solution for high-current motor drive circuits.

With built-in protections such as overcurrent limitation, overtemperature shutdown, and undervoltage lockout, the BTN7970B ensures reliable operation even in harsh environments. The integrated diagnostics and current sense functionality allow for precise monitoring and control. Its PWM capability up to 25 kHz and adjustable slew rate minimize EMI while enhancing efficiency. The compact PG-TO263-7-1 package provides excellent thermal performance, making it an ideal choice for compact and efficient designs.
