The L293 and L293D units are quadruple substantial existing half-H motorists. The L293 is meant to deliver bidirectional drive currents of as many as 1 A at voltages from 4.five V to 36 V. The L293D is designed to present bidirectional drive currents of approximately 600-mA at voltages from four.5 V to 36 V. Equally gadgets are created to push inductive hundreds these kinds of as relays, solenoids, DC and bipolar stepping motors, in addition as other higher present-day / higher voltage loads in good provide programs.

Every output is actually a comprehensive totem-pole travel circuit, using a Darlington transistor sink as well as a pseudo- Darlington resource. Motorists are enabled in pairs, with motorists one and 2 enabled by one,2EN and drivers three and 4 enabled by three,4EN. L293 and L293D are characterized for procedure from 0°C to 70°C.Other critical L293D options are:Extensive Supply-Voltage Range: four.5 V to 36 V. Different Input-Logic Source. Inside ESD Defense. High-Noise-Immunity Inputs. Output Current one A For every Channel (600 mA for L293D).

L293D is monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads and swiching power transistors.

peak Output Existing two A For every Channel (one.two A for L293D). Output Clamp Diodes for Inductive Transient Suppression (L293D).But L293 is a quadruple fifty percent h-bridge. Half an H-bridge will hook up an output pin to possibly Vcc or Floor or disconnect it. Using the just one it is possible to transform a DC motor on or off or implement to brake but can’t reverse the motor. To reverse a DC motor you'll need each halves of the H-bridge.
