Product Overview

The DS18B20+ is a programmable resolution 1-wire digital thermometer in 3 pin TO-92 package. This digital thermometer provides 9bit to 12bit celsius temperature measurements and has an alarm function with non-volatile user programmable upper and lower trigger points. The DS18B20 communicates over a 1-wire bus that by definition requires only one data line (and ground) for communication with central microprocessor. In addition, the device can derive power directly from data line (parasite power) by eliminating need for an external power supply. Each DS18B20 has a unique 64bit serial code stored in onboard ROM which allows multiple DS18B20 devices to function on the same 1-wire bus. Thus, it is simple to use one microprocessor to control many DS18B20 devices distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, process monitoring and control systems.
  • Supply voltage range from 3V to 5.5V
  • Measures temperatures from -55°C to 125°C (-67°F to +257°F)
  • ±0.5°C accuracy from -10°C to +85°C temperature range
  • No external components required
  • Parasitic power mode requires only 2 pins for operation (DQ and GND)
  • Simplifies distributed temperature sensing applications with multidrop capability
  • Reduce component count with integrated temperature sensor and EEPROM
  • Standby current of 750nA and active current of 1mA at VDD = 5V
  • Alarm search command identifies and addresses devices whose temperature is outside programmed limits

Applications

Sensing & Instrumentation, Consumer Electronics, Industrial, Medical
