Summary of STTS22H – LOW-VOLTAGE, ULTRA-LOW-POWER, 0.5 °C ACCURACY I2C/SMBUS 3.0 TEMPERATURE SENSOR
The STTS22H is an ultra-low-power, factory-calibrated digital temperature sensor in a 2 x 2 x 0.50 mm 6-lead UDFN package with exposed pad. It integrates a band-gap sensor, ADC, signal processing, and I²C/SMBus 3.0 interface, offering high accuracy (±0.5 °C from −10 °C to +60 °C), 16-bit output, one-shot mode, programmable thresholds with ALERT, and ultra-low current consumption over −40 °C to +125 °C.
Parts used in the STTS22H Project:
- STTS22H temperature sensor ASIC
- 2 x 2 x 0.50 mm 6-lead UDFN package with exposed pad
- I²C/SMBus 3.0 interface (serial communication protocol)
- Power supply (1.5 to 3.6 V)
- Interrupt/ALERT pin with programmable threshold circuitry
- Band-gap temperature sensing element
- On-chip A/D converter
- On-chip signal processing logic
The STTS22H is an ultra-low-power, high accuracy, digital temperature sensor offering high performance over the entire operating temperature range.
The STTS22H is a band gap temperature sensor coupled with an A/D converter, signal processing logic and an I²C/SMBus 3.0 interface all in a single ASIC.
This sensor is housed in a small 2 x 2 x 0.50 mm 6-lead UDFN package with exposed pad down for a better temperature match with the surrounding environment.
The STTS22H is factory calibrated and requires no additional calibration efforts on the customer side.
