The L293 and L293D are high-current quadruple half-H drivers. These devices are intended to power a variety of inductive loads, including relays, solenoids, DC and bipolar stepping motors, and other high-current and high-voltage loads. All inputs are TTL compatible and can withstand voltages of up to 7 V. Each output is an entire totem-pole drive circuit, complete with a Darlington transistor sink and a pseudo-Darlington source. Drivers are enabled in pairs, with 1,2EN enabling drivers 1 and 2 and 3,4EN enabling drivers 3 and 4. ... I have learned L293DNE from this article: https://www.apogeeweb.net/circuitry/l293dne-quadruple-half-h-drivers-datasheet-arduino-pinout.html If you get more ideas, please tell me.
IC from the last century. Using bipolar darlington as drivers, the IC typically loses 1,4V at the highside and 1.2V at the lowside. If you e.g. want to drive a 12V-Motor, a 12V-Power-supply will result in only 9.4V at the motor. Modern ICs have lower losses and allow for higher currents at comparable prices. Additionally, many of them have open-loop detection or overcurrent-protection.
