One primary application for the Aeroflex PCS5035, as shown below, would be to monitor the
temperature of different electronic bay areas in a Satellite, and report when any bay area has
exceeded a maximum temperature limit.
Thermistors with defined temperature characteristics are used as the sensors, and by providing
a constant stable current to the Thermistor, an accurate analog voltage of a specified
temperature trip point can be established. The comparator voltage reference input can be
tailored to set the trip point for the characteristic of the particular thermistor sensor used. The
on-board precision 2V reference can be used directly for voltages of 2 volts or less, or can be
scaled with an external operational amplifier to provide a voltage between 2 volts and the
maximum input of 3.1V. Various temperature trip points could be accomplished by using
thermistors with different temperature characteristics.
