Arduino / Raspberry Pi L293D H-Bridge 4 Channel Dc Motor Control Support Pulse With Modulation Input Voltage: DC4.5v - 25V Output Current: 600mA Per Channel Peak Current: 1.2A Non Repetitive Per Channel Enable Facility IC Protection: Auto Shut on High Temperature Logic: Logical 0 Input Voltage up to 1.5v High Noise Immunity Internal Clamp Diodes The Device 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 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.
