STCN75
Digital temperature sensor and thermal watchdog
Features
â Measures temperatures from â55°C to +125°C
(â67°F to +257°F)
â ±2°C accuracy from â25°C to
+100°C (max)
â Low operating current:125 µA (typ)
â No external components required
â 2-wire I2C/SMBus-compatible serial interface
â Selectable bus address allows connection
of up to eight devices on the bus
â Wide power supply range-operating voltage
range: 2.7 V to 5.5 V
â Conversion time is 45 ms (typ)
â Programmable temperature threshold and
hysteresis set points
â Pin- and software-compatible with TCN75
(Drop-in replacement)
â Power-up defaults permit standalone operation
as a thermostat
â Shutdown mode to minimize power
consumption
â Output pin (open drain) can be configured for
interrupt or comparator/thermostat mode (dual
purpose event pin)
â Packages:
â SO8
â MSOP8 (TSSOP8)
SO8 (M)
MSOP8
(TSSOP8) (DS)
