STMicroelectronics | STLM75DS2F

The STLM75DS2F is a high-precision digital CMOS temperature sensor IC with a sigma-delta temperature-to-digital converter and an I2C-compatible serial digital interface.

It is targeted for general applications such as personal computers, system thermal management, electronics equipment, and industrial controllers, and is packaged in the industry standard 8-lead TSSOP and SO8 packages.

Features:

• Measures temperatures from –55°C to +125°C (–67°F to +257°F)
• ±0.5°C (typ) accuracy
• ±2°C (max) accuracy from –25°C to +100°C
• Low operating current: 125 µA (typ)
• No external components required
• 2-wire I2C/SMBus-compatible serial interface
• Supports bus time-out feature
• Selectable bus address allows connection of up to eight devices on the bus
• Wide power supply range-operating voltage range: 2.7 V to 5.5 V
• Conversion time is 150 ms (max)
• Programmable temperature threshold and hysteresis set points
• Pin- and software-compatible with LM75 (dropin replacement)
• Power-up defaults permit standalone operation as a thermostat
• Shutdown mode to minimize power consumption
• Output pin (open drain) can be configured for interrupt or comparator/thermostat mode (dual purpose event pin)
• Packages:
• SO8
• MSOP8 (TSSOP8)
