BTM9021EP The MOTIX™ BTM9021EP is a fully integrated H-bridge motor driver with small footprint and adjustable slew rate at two levels for an improved EMC performance. It operates via SPI interface.
Overview
The MOTIX™ Full Bridge IC provides a cost optimized solution for easy design in. The supply voltage of the device is at 7 V to 18 V. It suits automotive applications with limitation of minimum 20A and covers PWM frequency of up to 20 kHz. BTM9021EP stands out due to its small (4,9 x 6,0mm) package with exposed pad leading to enhanced thermal conductivity. It features current sense for both, high side and low side.
