TC622/TC624
Low Cost Single Trip Point Temperature Sensor
Features: General Description: Temperature Set Point Easily Programs with a
Single External Resistor Operates with 2.7V Power Supply (TC624) TO-220 Package for Direct Mounting to Heatsink
(TC622XAT) or Standard 8-Pin PDIP and SOIC The TC622 and TC624 are programmable solid-state
temperature sensors designed to replace mechanical
switches in sensing and control applications. Both
devices integrate the temperature sensor with a
voltage reference and all required detector circuitry.
The desired temperature set point is set by the user
with a single external resistor. Applications: Power Supply Over-Temperature Detection
Consumer Electronics
Fire/Heat Detection
UPSs, Amplifiers, Motors
CPU Thermal Management in PCs Ambient temperature is sensed and compared to the
programmed set point. The OUT and OUT outputs are
driven to their active state when the measured
temperature exceeds the programmed set point.
The TC622 has a power supply voltage range of 4.5V
to 18.0V while the TC624 operates over a power supply
range of 2.7V to 4.5V. Both devices are usable over a
temperature range of -40В°C to +125В°C (TC622VXX,
TC624VXX). Both devices feature low supply current …
