TC1046
General description
The TC1046 is a linear output temperature sensor whose output voltage is directly proportional to measured temperature. The TC1046 can accurately measure temperature from -40°C to +125°C.
The output voltage range for these devices is typically 174mV at -40°C, 424mV at 0°C, 580 mV at +25°C, and 1205mV at +125°C. A 6.25mV/°C voltage slope allows for the wide temperature range.
The TC1046 is packaged in a 3-Pin SOT-23B package, making them ideal for space critical applications.
Feature
- Supply Voltage Range:2.7V to 4.4V
- Wide Temperature Measurement Range:-40°C to +125°C
- High Temperature Converter Accuracy:± 2°C, Max, at 25°C
- Linear Temperature Slope: 6.25 mV/°C
- Very Low Supply Current:35 µA Typical
- Small 3-Pin SOT-23B Package
Application
- Cellular Phones
- Power Supply Thermal Shutdown
- Temperature-Controlled Fans
- Temperature Measurement/Instrumentation
- Temperature Regulators
- Consumer Electronics
- Portable Battery-Powered Equipment

eSTS_ERR_ADC_OBJECT
NOTE :
Arduino, Mbeb, ModusToolbox not supported.
eCMD_READ
Feature :
Command that reads the AD conversion value, converts the AD conversion value to a characteristic Temperature, and stores the Temperature in rlt.
Process :
1. Read AD conversion value.
2. Convert AD conversion value to Temperature.
Voltage value = (AD conversion value × VDD) / ( 2AD bit )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
3. Store Temperature to rlt.
Command API function :
etSTS oTC1046_READ( float32* rlt )
Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX

eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT
NOTE :
Please execute this API function after starting AD conversion.
Arduino, Mbeb, ModusToolbox not supported.
eCMD_START_READ
Feature :
Command that starts AD conversion, waits for AD conversion to finish, reads out the AD conversion value, converts the AD conversion value to a characteristic Temperature, and stores the Temperature in rlt.
Process :
1. AD conversion start.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Temperature.
Voltage value = (AD conversion value × VDD) / ( 2AD bit )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
5. Store Temperature to rlt.
Command API function :
etSTS oTC1046_START_READ( float32* rlt )
Return value :
eSTS_FIN
