BD1020HFV

General description

The BD1020HFV is a low current consumption (4 µA), high accuracy temperature sensor. The IC itself detects temperature and outputs a linear voltage according to temperature.

Feature
  • Low thermal resistance package (standard 187°C/W)
  • Electrostatic breakdown voltage 8kV ( HBM )
  • Excellent power supply ripple rejection characteristics
Application
  • Smartphones (RF Module, Battery Charge Protection)
  • Audio system
  • DSC
  • DVC
  • LCD
  • PDP
  • DVD
  • BlueRay Optical Pickup Module

etCMD
eCMD_START


Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oBD1020HFV_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 oBD1020HFV_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 oBD1020HFV_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
