The LTC1163/LTC1165 triple low voltage MOSFET drivers
make it possible to switch supply or ground referenced
loads through inexpensive, low R
from as little as a 1.8V supply. The LTC1165 has inverting
inputs and makes it possible to directly replace P-channel
MOSFET switches while maintaining system drive polar-
ity. The LTC1163 has noninverting inputs.
Micropower operation, with 0.01 A standby current and
95 A operating current, coupled with a power supply
range of 1.8V to 6V, make the LTC1163/LTC1165 ideally
suited for 2- to 4-cell battery-powered applications. The
LTC1163/LTC1165 are also well suited for sub-3V, 3.3V
and 5V nominal supply applications.
The LTC1163/LTC1165 internal charge pumps boost the
gate voltage 8V above a 3.3V rail, fully enhancing inexpen-
sive N-channels for high- or low-side switch applications.
The LTC1163/LTC1165 are available in both an 8-pin DIP
and an 8-pin SOIC.

... The LTC1163 is noninverting; i.e., the MOSFET gate is driven above the supply when the input pin is held high. The LTC1165 is inverting and drives the MOSFET gate high when the input pin is held low. The inverting inputs of the LTC1165 allow P-channel switches to be replaced by lower resistance/cost N-channel switches while maintain- ing system drive polarity ...

... GS The startup current can be substantially reduced by limit- ing the slew rate at the gate of an N-channel as shown in Figure 1. The gate drive output of the LTC1163/LTC1165 is passed through a simple RC network, R1 and C1, which substantially slows the slew rate of the MOSFET gate to approximately 1.5 ...

... Because the input ESD protection diodes are referenced to ground instead of the supply pin 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 ...
