QUADRUPLE HALF-H DRIVER, L293D datasheet, L293D circuit, L293D data sheet: TI, alldatasheet, datasheet, Datasheet search site for Electronic Components. I shall also be explaining H-Bridge circuits, which motor drivers like the L293D are based on. This will be very useful in many robotics and electronics projects, so let’s get started! Role of H-Bridges in Driving Motors. A DC motor (Direct Current motor) is a motor which rotates when a voltage is applied at its terminals. L293D Motor Drivers Operates 4.5V to 36V whereas L298N can be Operates up to 46V 600mA Current can be drawn through both channels of L293D whereas L298 can draw up to 2A from both channels. L293 is quadruple motor driver uses half-H driver while L298 is dual full-H driver, i.e, in L293 all four.
The L293D belongs to a sort of h bridge motor driver shield, quadruple high-current half-H driver, used to provide bidirectional drive currents of up to 600 mA at voltages from 4.5 V to 36 V. The L293D IC is designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications. It can withstand a current up to 1200 mA in 100 microsecond and non-repetitive.
The L293D Motor Driver IC can control a set of two DC motors simultaneously in any direction. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo- Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN.
