MICROCHIP MCP9509HT-E/OT

The 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 100kΩ 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.
