25В°C, 35В°C, 45В°C, 55В°C, 65В°C, 75В°C, 85В°C,
95В°C, 105В°C, 115В°C, 125В°C Wide Operating Voltage Range: 2.7V to 5.5V Low Supply Current: 25 ВµA (typical) Temperature Switch Accuracy:
-В±1В°C (typical)
-В±4В°C (maximum) -15В°C to +75В°C
-В±6В°C (maximum) -40В°C to +125В°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 Microchip Technology’s MCP9501/2/3/4 family of
devices are temperature switches with В±1В°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 ВµA (typical), and the factory set thresholds provide
simplicity. – Uses External Pull-up Resistor
-Active-High, Push-Pull Output: MCP9502/4 User Selectable Hysteresis: 2В°C or 10В°C (typical) 5-lead SOT-23 package Applications In addition, this family of devices provide user
selectable 2В°C and 10В°C (typical) switch hysteresis,
and various output configurations. The MCP9501/2
outputs switch for rising temperatures while the …
