Applications
When output terminals short-circuit to VCC or GND, the voltage of 25pin is fixed to “L”.
And when shorting OUT
+ to OUT , “L” and “H” are switched according to an input signal.
Therefore, it is possible to judge how the power IC condition is if a micro-controller detects the
25pin voltage that is smoothed out with LPF.
It is recommend that the threshold voltage (Vth) is set up as higher as possible because output level
of LPF is changed according to an input signal.
(for example, Vth is set up to 4 V if 25pin is pulled up to 5 V line.)
Output voltage of L.P.F.
