LM26NV www.ti.com SNIS151B – AUGUST 2008 – REVISED MARCH 2013 LM26NV SOT-23, ±3°C Accurate, Factory Preset Thermostat (LM26 without VTEMP output) Check for Samples: LM26NV FEATURES 1 2 Internal Comparator with Pin Programmable 2°C or 10°C Hysteresis No External Components Required Open Drain or Push-Pull Digital Output; Supports CMOS Logic Levels Internal Temperature Sensor Internal Voltage Reference and DAC for Trip- Point Setting Currently Available in 5-Pin SOT-23 Plastic Package Excellent Power Supply Noise Rejection APPLICATIONS Microprocessor Thermal Management Appliances Portable Battery Powered Systems Fan Control Industrial Process Control HVAC Systems Remote Temperature Sensing Electronic System Protection KEY SPECIFICATIONS Power Supply Voltage: 2.7V to 5.5 V Power Supply Current: – 40µA(max) – 20µA(typ) Hysteresis Temperature: 2°C or 10°C(typ) DESCRIPTION The LM26NV is a precision, single digital-output, lowpower thermostat comprised of an internal reference, DAC, temperature sensor and comparator. Utilizing factory programming, it can be manufactured with different trip points as well as different digital output functionality. The trip point (TOS) can be preset at the factory to any temperature in the range of −55°C to +110°C in 1°C increments. The LM26NV has one digital output (OS/OS/US/US) and one digital input (HYST). The digital output stage can be preset as either open-drain or push-pull. In addition, it can be factory...
