MCP9501/2/3/4  
Temperature Switch with Selectable Hysteresis  
Description  
Features  
• Factory Set Temperature Switch  
Microchip Technology’s MCP9501/2/3/4 family of  
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:  
- TSET = -35°C,-25°C, -15°C, -5°C, 5°C, 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)  
Temperature Switch Accuracy:  
In addition, this family of devices provide user  
selectable 2°C and 10°C (typical) switch hysteresis,  
and various output configurations. The MCP9501/2  
outputs switch for rising temperatures while the  
MCP9503/4 switch for falling temperature, with the  
relative hysteresis at the set thresholds. This family of  
devices is also available with Active-High Push-Pull  
and Active-Low Open-Drain outputs, the MCP9502/4  
and the MCP9501/3, respectively. 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.  
- ±1°C (typical)  
- ±4°C (maximum) -15°C to +75°C  
- ±6°C (maximum) -40°C to +125°C  
• Switch Threshold Options (Hot/Cold):  
- Rising Temp.: MCP9501/2 (Hot Option)  
- Falling Temp.: MCP9503/4 (Cold Option)  
• Output Configuration Options:  
- Active Low, Open-Drain Output: MCP9501/3  
– Uses External Pull-up Resistor  
- Active-High, Push-Pull Output: MCP9502/4  
• User Selectable Hysteresis: 2°C or 10°C (typical)  
• 5-lead SOT-23 package  
The MCP9501/2/3/4 operate from 2.7V to 5.5V supply.  
This family is available with space saving 5-lead  
SOT-23 package.
