| Market Reality | The L293D is the motor and stepper driver of a million robotics courses and small CNC builds: four half-bridges (two full bridges), 600mA per channel with 1.2A peaks, and - the reason for the D - internal flyback diodes that the plain L293 leaves to the board. Its drop-in upgrade is the TI SN754410 at one amp pin for pin, and its famous neighbor is the L298N module: twice the current in a MultiWatt body, no internal diodes, and a logic supply that tolerates only 4.5-7V where the L293D accepts up to 36V. The substitution arithmetic between the two looks like a current question and is actually a supply-design question - the classic 12V-into-the-logic-pin death. | The L298N is the motor driver of the red breakout module that has fronted a million robots and CNC builds - a dual full-bridge in MultiWatt-15 with 2A-per-channel capability and a price that made it the default. Its reputation runs ahead of its datasheet in one direction only: the Darlington output stage drops 1.4V to 3V depending on current, which on a 6V robot supply is a third of the battery spent as heat. The bare chip also needs external flyback diodes that the modules provide and small repairs often omit. Two honest conversations belong on this page: L293D is the smaller cousin with built-in diodes, and the modern MOSFET drivers (TB6612FNG and the DRV row) are the reason new designs stopped choosing this part. |
