TC1046

TC1046 is a temperatures sensor IC (-40 °C to +125 °C) made by Microchip Technology. This posting will provide the OSS-ECAL(Open Source Software for Electronic Components Abstraction Layer) for TC1046.
MCU interface : ADC

CAUTION:Please be sure to refer to the latest version of the Datasheet prior to actual design.

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

Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oTC1046_START( void )

Return value :
eSTS_FIN
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
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_HAL_ADC
eSTS_ERR_COMMAND_CODE
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
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT
