... The current limit value of the DCM driver is determined by the VREF voltage and the resistance (RNF) connected across the RNF and GND pins using the following formula : Ilimit [A] = (VREF [V] /5) /RNF [Ω]) Assuming VREF = 1.5V, RNF = 0.2Ω, the current limit is : Ilimit = 1.5V/5/0.2Ω = 1.5A LV8760T Output OUTA OUTB * ...

... Output short-circuit protection function The LV8760T incorporates an output short-circuit protection circuit. It turns the ouputs off to prevent destruction of the problem such as an output pin being shorted to the motor power supply or ground occurs. 1.Protection function operation (Latch method) The short-circuit protection circuit is activated when it detects the output short-circuit state. If the short-circuit state continues for the internally preset period (≈ ...
