L293D Motor Driver

This is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC and stepping motors) and switching power transistors. To simplify the use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. This device is suitable for use in switching applications at frequencies up to 5 kHz.

The L293D is assembled in a 16 lead plastic package which has 4 centre pins connected together and used for heatsinking

Specifications:

  • Voltage: 4.5V - 36V
  • 600mA Output Current Capability per Channel
  • 1.2A Peak Output Current (non-repetitive)
  • Overtemperature Protection
