General Description
The TCN75 is a serially programmable temperature
sensor that notifies the host controller when ambient
temperature exceeds a user programmed set point.
Hysteresis is also programmable. The INT/CMPTR
output is programmable as either a simple comparator
for thermostat operation or as a temperature event
interrupt.
accomplished via a two-wire bus that is compatible with
industry standard protocols. This permits reading the
current temperature, programming the set point and
hysteresis, and configuring the device.
The TCN75 powers up in Comparator mode with a
default set point of 80°C with 5°C hysteresis. Defaults
allow
thermostat. A shutdown command may be sent via the
2-wire bus to activate the low power Standby mode.
Address selection inputs allow up to eight TCN75s to
share the same 2-wire bus for multizone monitoring.
All registers can be read by the host and the INT/
CMPTR output's polarity is user programmable. Both
polled and interrupt driven systems are easily
accommodated. Small physical size, low installed cost,
and ease of use make the TCN75 an ideal choice for
implementing
schemes.
