Indicates over-current, over-temperature (ITRIP), or low-side undervoltage lockout has occurred.
This pin has negative logic and an open-drain output. The use of over-current and over-
temperature protection requires the use of external components.
Logic input to shutdown functionality. Logic functions when EN is high (i.e., positive logic). No
effect on FAULT and not latched.
Analog input for over-current shutdown. When active, ITRIP shuts down outputs and activates
FAULT and RCIN low. When ITRIP becomes inactive, FAULT stays active low for an externally
set time t_FLTCLR, then automatically becomes inactive (open-drain high impedance).
An external RC network input used to define the FAULT CLEAR delay (t_FLTCLR) approximately
equal to R*C. When RCIN > 8 V, the FAULT pin goes back into an open-drain high-impedance
state.
