DC Motor Drive

Allegro Microsystems DC Motor DriveDesigned for pulse width modulated (PWM) control of a low voltage DC motor, Allegro MicroSystems' A3918 is capable of output currents up to 1.5 A and operating voltages from 2.5 to 9 V. The A3918 has an internal fixed off-time PWM timer that sets a peak current based on the selection of a current sense resistor. An overcurrent output flag is provided that notifies the user when the current in the motor winding reaches the peak current determined by the sense resistor.
