Description
AI
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
2°C and 10°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 kO pull-up
resistor.
