preventing any damages to the device while a
fault condition is reported by the error flag
signal. A built-in 10°C hysteresis allows the
device to cool down to 125°C before resuming
normal operations on the faulty channel at
which point the error flag signal is cleared.

U
NDER-VOLTAGE LOCKOUT
T
EST CIRCUIT
Under-voltage lockout function (UVLO) keeps
the internal power switch from being turned
on until the power supply has reached at least
1.68V, even if the switch is enabled. Upon
detection
of
an
input
voltage
below
approximately 1.68V, the power switch is
turned off while a fault condition is reported by
the error flag signal.
T
HERMAL PROTECTION
Internal thermal sensing circuitry monitors the
operating temperature of the device for each
channel independently. Upon detection of a
temperature in excess of 135°C, the power
switch for the given channel is disabled
