LTC1153
PI FUU
Drain Sense Pin
The drain sense pin is compared against the supply pin
voltage.
If the voltage at this pin is more than 100mV
below
the supply pin, the input latch will trip and the
MOSFET switch will be turned off.
This pin is also a high impedance CMOS gate with ESD
protection and therefore should not be forced beyond the
power supply rails.
Some loads, such as large supply capacitor, lamps, or
motors require high inrush currents. An RC time is added
between the sense resistor and the drain sense pin to
ensure that the drain sense circuitry does not false trigger
U
during start-up. This trip delay can be set from a few
microseconds to many seconds. However, very long de-
lays may put the MOSFET switch in risk of being destroyed
by a short-circuit condition. (see Applications Information
Section).
Status Pin
The status pin is an open-drain output which is driven low
whenever the breaker is tripped. A 51k pull-up resistor
should be connected between this output and a logic
supply. The status pins of multiple LTC1153s can be OR’d
together if independent fault sensing is not required. No
connection is required to this pin when not in use.
