TC72, TC74, TC77, TCN75 and MCP9800/1/2/3
Serial Output Temperature Sensor Family
Product Summary:
The TC74, TCN75 and MCP9800/1/2/3 are
temperature sensors with an on-board thermal diode
and an industry standard 2-wire serial interface. The
TC72 and TC77 are temperature sensors with an
on-board thermal diode and an SPI™ compatible
interface.
Microchip’s serial (digital) output temperature sensors
offer excellent temperature accuracy (±0.5°C typical)
with a very low operating current of less than 250 µA.
Communication with the devices is accomplished via
an industry standard I
interface protocol. A Standby mode is also available
for further reducing the total current. All devices are
offered in space-saving packages and feature very fast
temperature conversion times. Temperature resolution
for the entire family ranges from 0.0625°C to 1°C.
These temperature sensors are fully specified from 2.7V
to 5.5V and allow temperature measurement over an
extended -55°C to +125°C temperature range,
(-40°C to +125°C for the TC74). Several features
provided on select devices, address a broad application
spectrum: interrupt output for thermal event alarm,
external address pins for multi-drop capability,
programmable trip-point for maximum flexibility, one-shot
temperature measurement for further power reduction
and small footprints for board space savings.
High accuracy, low-operating current, small size and
ease-of-use make these devices ideal for implementing
sophisticated thermal management schemes in a variety
of systems.
Typical applications for these devices include:
•
•
•
•
PCs, servers, datacom equipment, hard drives
Set-top boxes, storage equipment, consumer
electronics
Power supplies, communication devices, office
electronics and amplifiers
General purpose temperature monitoring
