What are the key features of E-L293D?
- 4 push-pull output channels at up to 600 mA each and 36 V supply, enabling simultaneous control of 2 independent DC motors or 1 bipolar stepper motor
- Integrated clamp diodes on all outputs protect against inductive flyback from motor coils without requiring external protection components
- TTL and CMOS logic-compatible inputs allow direct connection to 3.3 V or 5 V microcontrollers including Arduino and PIC platforms
What is E-L293D used for?
The E-L293D is widely used in hobbyist robotics, CNC pen plotters, and educational motor control kits where two bidirectional DC motors or a bipolar stepper need to be driven from a single IC. Its 36 V motor supply and separate 5 V logic supply allow the control MCU and motor to operate from independent rails, preventing voltage spikes from affecting digital logic. The 20-pin SO surface-mount package makes it suitable for compact PCB designs in smart home appliances and toy robotic arms.

Frequently Asked Questions
How many DC motors can E-L293D control simultaneously, and what current does each output channel support?
The E-L293D drives up to 2 independent bidirectional DC motors simultaneously using its 4 push-pull output channels arranged as 2 H-bridge pairs. Each channel sources or sinks up to 600 mA continuous current at motor supply voltages up to 36 V, with peak currents tolerated briefly during motor startup or stall conditions.
Does E-L293D require external flyback diodes when driving inductive loads like motors or solenoids?
No. The E-L293D integrates clamp diodes on all 4 output pins, providing built-in protection against inductive flyback voltages generated when motor or solenoid coils switch off. This eliminates the need for 8 external Schottky or fast-recovery diodes typically required in discrete H-bridge circuits, reducing PCB area and component count.
Can E-L293D drive a bipolar stepper motor, and what winding current and supply voltage are compatible?
Yes. By using both H-bridge pairs in the E-L293D together, the device drives a bipolar stepper motor with winding currents up to 600 mA per winding at supply voltages from 4.5 V to 36 V. Step sequencing is controlled by the 4 input logic lines, allowing a microcontroller to generate full-step or half-step patterns for smooth rotation in small positioning or scanning mechanisms.
