3.3 Control output section (/FAULT)
Figure 5 Schematic of the structure of the /FAULT-pin
This pin indicates the failure status of the IC. The level of this pin is LOW in case of undervoltage lockout or
triggering of the overcurrent protection. An external pull-up resistor to VDD in the range of a few kΩ (e.g. 4.7 k)
is necesary for this open drain pin. The voltage at this pin is internally clamped to VCC, as one can see in the
internal structure according to Figure 5,. The internal pull-down FET has a typical resistance of R
ON,FLT
= 61 .
The delay time from the triggering event to the change of status at the /FAULT-pin is t
FLT
= 450 ns typically
according to the timing diagram shown in Figure 6.
