L293d Motor Driver Circuit Diagram. H bridge is the simplest circuit for controlling a low current rated motor. Drivers are enabled in pairs with drivers 1 and 2 enabled by 1 2en and drivers 3 and 4 enabled by 3 4en.
These ics are designed to control 2 dc motors simultaneously. For driving the motors it has a separate provision to provide motor supply vss v supply. L293d is a suitable device to use for stepper motors gear motors etc.
L293d consist of two h bridge.
As well this ic can drive small and quiet big motors. Each output is a complete totem pole drive circuit with a darlington transistor sink and a pseudo darlington source. This ic consists of 16 pins which are used to control a set of two dc motors instantaneously in any direction. H bridge is the simplest circuit for controlling a low current rated motor.
