Fault Status Output
The FAULT signal is an active-low output with a weak pull-
up. FAULT is asserted when either an overcurrent or thermal
shutdown condition occurs. In the case of an overcurrent
condition, FAULT will be asserted only after the flag response
delay time, t
asserted only upon valid overcurrent conditions and that
erroneous error reporting is eliminated. The FAULT response
delay time t

Undervoltage Lockout
Undervoltage lockout (UVLO) prevents the output MOSFET
from turning on until the AUX input exceeds approximately
3.5V. UVLO ensures that the output MOSFETs remain off to
prevent high transient inrush current due to stray or bulk load
capacitance. This helps to ensure that the power supply
voltage regulation is preserved and also prevents possible
damage to sensitive components.
