MCP9501/2/3/4  
Temperature Switch with Selectable Hysteresis  
Description  
Features  
• Factory Set Temperature Switch  
Microchip Technology’s MCP9501/2/3/4 family devices  
are temperature switches with ±1°C (typical) accurate  
factory set output thresholds. These devices are ideal for  
high-power supply systems where an overtemperature  
protection circuit is needed. These devices do not  
require external components, consume 25 µA (typical),  
and the factory set thresholds provide simplicity.  
• Available Temperature Switch Thresholds:  
- T  
= -35°C, -25°C, -15°C, -5°C, +5°C,  
SET  
+15°C, +25°C, +35°C, +45°C, +55°C, +65°C,  
+75°C, +85°C, +95°C, +105°C, +115°C,  
+125°C  
• Wide Operating Voltage Range: 2.7V to 5.5V  
• Low Supply Current: 25 µA (typical)  
In addition, this family of devices provides  
user-selectable +2°C and +10°C (typical) switch hyster-  
esis, and various output configurations. The MCP9501/2  
outputs switch for rising temperatures, while the  
MCP9503/4 devices switch for falling temperatures, with  
the relative hysteresis at the set thresholds. This family  
of devices is also available with an active-high, push-pull  
output (MCP9502/4) and an active-low, open-drain  
output (MCP9501/3). The push-pull output is ideal for a  
microcontroller interface, while the open-drain output  
can be used for level shifting, wired-OR configuration or  
as a heater on/off switch.  
• Qualification: AEC-Q100 Rev. G, Grade 1  
(-40°C to +125°C)  
Temperature Switch Accuracy:  
- ±1°C (typical)  
- ±4°C (maximum) between -15°C to +75°C  
- ±6°C (maximum) between -40°C to +125°C  
• Switch Threshold Options (Hot/Cold):  
- Rising temperature: MCP9501/2 (Hot option)  
-
Falling temperature: MCP9503/4 (Cold option)  
• Output Configuration Options:  
The MCP9501/2/3/4 devices operate from a 2.7V to 5.5V  
supply. This family is available with the space-saving  
5-lead SOT-23 package.  
- Active-low, open-drain output: MCP9501/3  
- Uses external pull-up resistor  
- Active-high, push-pull output: MCP9502/4
