perature exceeds a user-programmed setpoint. Hysteresis
is also programmable. The INT/CMPTR output is program-
mable as either a simple comparator for thermostat opera-
tion or as a temperature event interrupt. Communication
with the TCN75 is accomplished via a two-wire bus that is
compatible with industry standard protocols. This permits
reading the current temperature, programming the setpoint
and hysteresis, and configuring the device.
The TCN75 powers up in Comparator Mode with a
default setpoint of 80
°
C with 5
°
C hysteresis. Defaults allow
independent operation as a stand-alone thermostat. A shut-
down command may be sent via the 2-wire bus to activate
the low-power standby mode. Address selection inputs
allow up to eight TCN75's to share the same 2-wire bus for
multi-zone 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 sophisticated
system management schemes.
TelCom Semiconductor reserves the right to make changes in the circuitry and specifications of its devices.
