Utilizing • No External Components Required factory programming, it can be manufactured with • Open-Drain or Push-Pull Digital Output; Supports different trip points as well as different digital output functionality. The trip point (TOS) can be preset at the CMOS Logic Levels factory to any temperature in the range of −55°C to • Internal Temperature Sensor With VTEMP Output 110°C in 1°C increments. The LM26 has one digital Pin output (OS/OS/US/US), one digital input (HYST) and • VTEMP Output Allows After-Assembly System one analog output (VTEMP). The digital output stage Testing can be preset as either open-drain or push-pull. In addition, it can be factory programmed to be active • Internal Voltage Reference and DAC for Trip-Point HIGH or LOW. The digital output can be factory Setting programmed to indicate an over temperature • Currently Available in 5-pin SOT-23 Plastic shutdown event (OS or OS) or an under temperature Package shutdown event (US or US). When preset as an • Excellent Power Supply Noise Rejection overtemperature shutdown (OS) it will go LOW to indicate that the die temperature is over the internally • UL Recognized Component preset TOS and go HIGH when the temperature goes • Key Specifications below (TOS–THYST). Similarly, when preprogrammed – Power Supply Voltage 2.7 V to 5.5 V as an undertemperature shutdown (US) it will go HIGH to indicate that the temperature is below TUS – Power Supply Current and go LOW when the temperature is above 40 μA (Maximum) 16 μA (Typical) (TUS+THYST). The typical hysteresis, THYST, can be set – Hysteresis Temperature 2°C or 10°C (Typical) to 2°C or 10°C and is controlled by the state of the HYST pin. A VTEMP analog output provides a voltage 2 Applications that is proportional to temperature and has a −10.82 mV/°C output slope. • Microprocessor Thermal Management • Appliances Available parts are detailed in the Device Comparison Table.
