Datasheet TLE 6228 G P

Note 1) : Standby is not designed for switching or PWM operation of the outputs

Note 2) : overload/short-to-supply/overtemperature - events shorter than min. time tDSO specified in 2.10

will not be latched and not reported at the status pin.

Note 3) : to reset latched status-output in case of overload/short-to-supply/overtemperature the control

input has to go low and stay low for longer than max. input suppression time tD-IN specified in 2.13 of the
