MCP9509/10 Resistor-Programmable Temperature Switches Features Description Resistor-Programmable Temperature Switch Microchip Technologys MCP9509/10 devices are pro- grammable logic output temperature switches. The Wide Operating Voltage Range: 2.7V to 5.5V temperature switch threshold can be programmed with Low Supply Current: 30 A (typical) a single external resistor, which provides high design Temperature Switch Accuracy: flexibility and simplicity. In addition, this family of - 0.5C (typical) at +25C, +45C devices provide user programmable features such as - 1C (typical) 0C to +70C 2C and 10C (typical) switch hysteresis and output structure configuration. The MCP9509 provides an - 3.5C (maximum) 0C to +125C open drain output, whereas the MCP9510 is offered in - 4.5C (maximum) -20C to +125C three different user selectable output configurations: - 2C (typical) -40C to +125C Active-low/Active-high push pull and Active-Low Sensor Options available: Open-Drain output with an internal 100k pull-up - Switch for rising temperature: Cold to Hot (H) resistor. to Cold (C) - Switch for falling temperature: Hot The MCP9509/10 operate from 2.7V to 5.5V. This Output Configurations: family is capable of triggering for temperatures -40C to - Open-Drain: +125C with high accuracy.
