TC6501/2/3/4  
Ultra Small Temperature Switches  
with Pin Selectable Hysteresis  
Features  
General Description  
• 5-Pin SOT-23A  
The TC6501/2/3/4 are SOT-23 temperature switches  
that require no external components and are available  
with factory-programmed temperature thresholds. A  
choice of factory-trimmed temperature trip points are  
also available. Pin-selectable hysteresis of +2°C or  
+10°C allows flexibility to the design of the application.  
These parts typically consume only 17 µA of current  
and operate over the entire -55°C to +135°C  
temperature range, while offering accuracies of ±0.5°C  
(typ).  
• Factory-programmed Thresholds from  
-45°C to +125°C in 10°C Increments  
• Pin Selectable +2°C or +10°C Hysteresis  
• ±0.5°C (Typ) Threshold Accuracy Over Full  
Temperature Range  
• No External Components Required  
• 17 µA Supply Current (Typ)  
Applications  
The TC6501 and TC6503 have an open-drain, active-  
low output, which targets microcontroller reset control.  
The TC6502 and TC6504 have a CMOS, active-high  
output designed to drive the logic level MOSFET that  
turns on a fan or heater element.  
• Thermal Management in PCs and Servers  
• Over-temperature Fail-safe Circuits  
• Simple Fan Controller  
Temperature Alarms  
The TC6501/TC6502 are designed for hot temperature  
monitoring (+35°C to +125°C). These devices assert a  
logic signal when the temperature goes above the  
threshold. The TC6503/TC6504 are optimized for cold  
temperature monitoring (-45°C to +15°C) and assert a  
logic signal when the temperature goes below the  
threshold.  
• Projectors/Printers  
• Notebook Computers  
• Network Boxes  
Package Types  
The TC6501/2/3/4 are offered with five standard tem-  
perature thresholds. Available in 5-Pin SOT-23A pack-  
ages, these parts are ideal for applications requiring  
high integration, small size, low power and low installed  
cost.
