... After the set design, be sure to verify the design with the actual product. Confirm the solder joint state and verify also the reliability of solder joint for the Exposed Die-Pad, etc. Any void or deterioration, if observed in the solder joint of these parts, causes deteriorated thermal conduction, possibly resulting in thermal destruction of IC.

... 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 LV8761V Output OUTA OUTB * ...

... Output short-circuit protection function The LV8761V incorporates an output short-circuit protection circuit that turns off the output to prevent the IC from fatal damage when the output is short-circuited due to short-to-power or short-to-ground fault. Either the “latch-type,” in which the output off state is latched when the short-circuit protection circuit is activated, or “auto reset-type,” in which the output on/off states are repeated when the short-circuit protection circuit is activated, can be selected ...

... Condition Warning Output Pin (EMOT) The LV8761V is provided with the EMOT pin which notifies the CPU of an unusual condition if the protection circuit operates by detecting an abnormal condition of the IC. This pin is of the open-drain output type and requires a pull-up resistor when to be used. ...
