if the worst-case current is 1.5A, you're probably OK -- the SN754410's have thermal protection for over-current conditions. they're rated for an amp continuous, so you're not too far out of bounds. one cause for concern is if the 1.5A measure is (...)

I am trying to determine whether the SN754410 motor drivers will support two small DC motors. (without killing the IC's or motor) Or will I need to add a power amplification circuit.

Dear Mike, I believe the 16 V is rms value. If you attach a capacitor across the bridge rectifier under no load condition(output terminals are open), the capacitor gets charged not to 16 V rms but to the maximum value ie Vm=16*2^0.5 which is about (...)
