APPLICATIO S I FOR ATIO
TYPICAL APPLICATIO S
LTC1163/LTC1165
managed by the system regulator. R2 is required to
eliminate the possibility of parasitic MOSFET oscillations
during switch transitions. It is a good practice to isolate the
gates of paralleled MOSFETs with 1k resistors to decrease
the possibility of interaction between switches.
Mixed 5V/3V Systems
Because the input ESD protection diodes are referenced to
ground instead of the supply pin, it is possible to drive the
LTC1163/LTC1165 inputs from 5V CMOS or TTL logic
even though the LTC1163/LTC1165 are powered from a
3.3V supply as shown in Figure 2. The input threshold
voltage is approximately 50% of the supply voltage or 1.6V

Reverse Battery Protection
The LTC1163/LTC1165 can be protected against reverse
battery conditions by connecting a 150 resistor in series
with the ground pin or supply pin. The resistor limits the
supply current to less than 24mA with –3.6V applied.
Because the LTC1163/LTC1165 draw very little current
while in normal operation, the drop across the resistor is
minimal. The 3.3V P (or control logic) can be protected by
adding 10k resistors in series with the input pins.
on a 3.3V supply which is compatible with 5V TTL and
CMOS logic. (The LTC1163/LTC1165 cannot however, be
driven by 3V logic when powered from a 5V supply
because the threshold is approximately 2.5V.)
