NOTE :
(1) In case of undervoltage, tristate and status-flag are reset automatically.
(2) Whenever over-current or over-temperature is detected, the fault is stored (i.e.status-flag remains low).
The tristate conditions and the status-flag are reset via DI1 (IN1) or DI2 (IN2).
Pinnames in brackets refer to coding pin (COD=Vcc).
(3) If COD = Vcc then DI1 and DI2 are not active.
(4) In case of over-current, the time when the current is greater than 7,8A is lower than 30µs, with a maximum frequency of 1kHz.
(5) COD=nc or GND
