Dual full-bridge PWM motor driver IC saves space

October 04, 2016 // By Julien Happich
Allegro MicroSystems Europe has released a 40V dual full-bridge driver capable of driving two DC motors with outputs rated up to 3.2A.

The A5995 device includes fixed off-time pulse-width modulation (PWM) regulators for current control. Each DC motor can be controlled in forward, reverse, coast and brake modes with industry standard PHASE and ENABLE inputs.  Fast or slow PWM current decay is selected via the MODE input. Protection features include thermal shutdown with hysteresis, undervoltage lockout (UVLO), crossover current, and overcurrent protection. Low current sleep mode is included to improve efficiency. The A5995 comes in a leadless 6×6×0.9mm 36-pin QFN package with exposed power tab for enhanced thermal performance.
