ISL6174
Dual Low Voltage Circuit Breaker
This IC targets dual voltage hot swap applications across the
+2.5V to +3.3V (nominal) bias supply voltage range with a
second lower voltage rail down to less than 1V where a circuit
breaker response to an over current event is preferred.
It features a charge pump for driving external N-Channel
MOSFETs, accurate programmable circuit breaker current
thresholds and delay output undervoltage monitoring and
reporting and adjustable soft-start.
The circuit breaker current level (I
CB
) for each rail is set by
two external resistors, and for each rail a delay (t
CB)
is set by
an external capacitor on the TCB pin. After t
CB
has expired,
the IC then quickly pulls down the associated GATE(s)
output turning off its external FET(s).

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free soldering
operations). Intersil Pb-free products are MSL classified at Pb-free
peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
