DC Motor Driver (12 V 5 A) to control 4 DC Motors

Please suggest a motor diver circuit for controlling 4 DC motors that need to operate at 12 V and ma. current 5-6 Amperes (each motor).

Hello Deepesh,
Please see the link below for the sample circuit. The circuit uses only one motor on the design. Try to redesign the circuit to cater four motors on the output side.

Hi Deepesh,

You can also try L293D a Quadruple half-H driver IC of texas instrument designed IC for motors or the A3988 which is a Quad DMOS Full Bridge PWM Motor Driver of Allegro. Good Luck

thanks Neil,

but the current requirement for the motors is 5A, L293 and A3988 can only be used at 1-1.5 A.

The LT1158 might do the job. For 24 amps N-channel MOSFETs having ON resistance of 4 millohms will work with minimal heatsinking; the PCB can be used to dissipate the ~1.5 watts per MOSFET.
