GENERAL DESCRIPTION
The Aeroflex Plainview PCS5035 contains "Five Monolithic" precision current sources designed for
thermistor current monitor and resistive sensor applications. The precision current source
(80µA ±2µA)/Comparator inputs are compared to an external reference of 0VDC to 3VDC. A precision internal
2.0VDC reference is provided if an external reference is not available. See Figure 1.
The comparator outputs of two (2) PCS5035 can be wired or’ed to provide 10 sensors inputs. Current source
output/comparator inputs of two or more units can be tied together to provide more sensor current. A logic
"high" of 3.4VDC maximum on the enable pin turns on the current source/comparators. Any unused current
source output/comparator inputs can be left open circuit without affecting other I/O’s.

One primary application for the Aeroflex PCS5035, as shown in Figure 3 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 external Thermistor (Temp T1 to Temp T5), 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.
