TYPICAL PERFORMANCE CHARACTERISTICS
PIN FUNCTIONS
Input and Shutdown Pins
The LTC1154 input pin is active high and activates all of the
protection and charge pump circuitry when switched ON.
The shutdown pin is designed to immediately disable the
switch if a secondary fault condition (over temperature,
etc.) is detected. The LTC1154 logic and shutdown inputs
are high impedance CMOS gates with ESD protection
diodes to ground and supply and therefore should not be
forced beyond the power supply rails. The shutdown pin
should be connected to ground when not in use.

ENABLE Input Pin
The ENABLE input can be used to enable a number of
LTC1154 high side switches in banks or to provide a sec-
ondary means of control. It can also act as an inverting
input. The ENABLE input is a high impedance CMOS gate
with ESD clamp diodes to ground and supply and therefore
should not be forced beyond the power supply rails. This
pin should be grounded when not in use.
