Applications
25pin voltage that is smoothed out with LPF.
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.)
When output terminals short-circuit to V
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
It is recommend that the threshold voltage (Vth) is set up as higher as possible because output level
