One more type of quadruple high-current half-H driver IC is discussed here. It isthe SN754410. The main function ofSN754410 Test Circuit and Switching Timesthe IC is to convert low voltage, low current logic signals to high voltage, high current signals to directly drive a motor as mentioned in the previously article. The SN754410 is designed to provide bidirectional drive currents up to 1 A at voltages from 4.5 V to 36 V.

Seemed similar to the L293, butthe SN754410 has Improved Functional Replacement for the SGS L293, No Output Glitch During Power Up or Power Down, Sink/Source Interlock Circuitry Prevents Simultaneous Conduction and Include both Half-H and Full-H Solenoid Drivers and Motor Drivers in its feature. Other features are relatively the same of this type of IC for example its Wide Supply-Voltage Range of 4.5 V to 36 V, Thermal Shutdown, TTL and CMOS-Compatible High-Impedance Diode-Clamped Inputs.

In thisSN754410 Datasheet, it is described the recommended operating conditions. There are VCC1= 4.5-5.5 V, VCC2= 4.5-36 V, VIH= 2-5.5 V, VIL= -0.3 – 0.8 V, TJ(junction temperature)= -40 – 125 °C, and TA= -40 – 85 °C. For switching characteristics, VCC1 = 5 V, VCC2 = 24 V, CL = 30 pF, TA = 25°C. A separate supply voltage (VCC1) is provided for the logic input circuits to minimize device power dissipation. Supply voltage VCC2 is used for the output circuits. This characteristics suits for dc and bipolar stepping motors, and Positive-Supply Applications.
