1V 9087 Units 6 Lots 8% 4% 0% Temperature Accuracy (°C) 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 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 kΩ pull-up resistor.
The MCP9509/10 operate from 2.
7V to 5.
5V.
This family is capable of triggering for temperatures -40°C to +125°C with high accuracy.
