L293D Motor Driver IC
L293D Motor Driver IC
L293D IC generally comes as a standard 16-pin DIP (dual-in-line package). This motor driver IC can simultaneously control two small motors in either direction; forward and reverse with just 4 microcontroller pins (if you do not use enable pins).
Each chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor.
A motor driver is basically a current amplifier that takes a low-current signal from the microcontroller and gives out a proportionally higher current signal which can control and drive a motor. In most cases, a transistor can act as a switch and perform this task which drives the motor in a single direction.
Turning a motor ON and OFF requires only one switch to control a single motor in a single direction.

1. What is the L293D motor driver IC?
- L293D IC is typically available as a standard 16-pin DIP package (dual-in-line package). With just four microcontroller pins, this motor driver IC can control two small motors in either direction; forward or reverse (if you do not use enable pins).
2. Why L293D IC is used?
- The L293D is a 16-pin Motor Driver IC that can control two DC motors in any direction at the same time. The L293D is capable of bidirectional drive currents of up to 600 mA (per channel) at voltages ranging from 4.5 V to 36 V. It can be used to control small dc motors, such as toy motors.
3. Which driver IC is used to drive DC motors?
- The L293D is a dual-channel H-Bridge motor driver that can power two DC motors or one stepper motor. This is an integrated circuit chip that regulates motors in self-driving robots.
