New drivers enable fewer external components and smaller footprints while improving performance

Allegro MicroSystems has released two new full-bridge gate drivers for automotive and industrial applications. Available with direct control (A89505) and pulse-width modulation (A89506) options, these devices up-integrate critical features to make system design easier, replacing mechanical relays with solid-state drivers to improve performance and reliability. With built-in capabilities including flexible interface logic, EMI mitigation with programmable gate drive, motor current feedback and multiple diagnostic features, these devices require very few external components and are available in a 4x4 mm QFN package, 36% smaller than comparable 5x5 mm devices.
