Description

STCN75 Digital temperature sensor and thermal watchdog 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 – 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 45 ms (typ) ■ Programmable temperature threshold and hysteresis set points ■ Pin- and software-compatible with TCN75 (drop-in 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) ■ MSOP8 (TSSOP8) package Datasheet − production data MSOP8 (TSSOP8) March 2012 This is information on a product in full production.
