Characteristics and Specifications

The L293 and L293D devices are quadruple substantial present half-H drivers. The L293 is meant to give bidirectional push currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is designed to give bidirectional travel currents of as many as 600-mA at voltages from 4.five V to 36 V. Both units are designed to generate inductive loads this kind of as relays, solenoids, DC and bipolar stepping motors, likewise as other significant current / superior voltage loads in positive source apps.

Each and every output is really a complete totem-pole generate circuit, using a Darlington transistor sink as well as a pseudo- Darlington resource. Drivers are enabled in pairs, with drivers 1 and 2 enabled by one,2EN and motorists 3 and 4 enabled by 3,4EN. L293 and L293D are characterized for procedure from 0°C to 70°C.Other essential L293D functions are:Extensive Supply-Voltage Array: four.five V to 36 V. Different Input-Logic provide. Inner ESD Safety. High-Noise-Immunity Inputs. Output Latest one A For each 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 Current 2 A For every Channel (1.two A for L293D). Output Clamp Diodes for Inductive Transient Suppression (L293D).But L293 is actually a quadruple fifty percent h-bridge. Fifty percent an H-bridge will join an output pin to either Vcc or Floor or disconnect it. Using the one particular you are able to flip a DC motor on or off or use to brake but cannot reverse the motor. To reverse a DC motor you require both equally halves of the H-bridge.
