MCP9509/10
Resistor-Programmable Temperature Switches
Features Description Microchip Technology’s MCP9509/10 devices are programmable logic output temperature switches. The
temperature switch threshold can be programmed with
a single external resistor, which provides high design
flexibility and simplicity. In addition, this family of
devices provide user programmable features such as
2В°C and 10В°C (typical) switch hysteresis and output
structure configuration. The MCP9509 provides an
open drain output, whereas the MCP9510 is offered in
three different user selectable output configurations:
Active-low/Active-high push pull and Active-Low
Open-Drain output with an internal 100 kО© pull-up
resistor. Resistor-Programmable Temperature Switch
Wide Operating Voltage Range: 2.7V to 5.5V
