S-5813A series (S-5813A, S-5814A)

General description

The S-5813A/5814A Series is a family of high-precision temperature sensor ICs on a single chip with a linear output voltage for temperature changes.
Each chip is composed of a temperature sensor, a constant current circuit, and an operational amplifier.
The operating ambient temperature is from –40°C to +100°C. These devices have much better linearity than other temperature sensors such as thermistors, and can be used for a wide range of temperature control applications.

Feature

S-5813A : ±5.0°C (–30°C to +100°C)
S-5814A : ±2.5°C (–30°C to +100°C)
Linear output voltage
–11.04 mV/°C typ.
Ta = -30°C : 2.582 V typ.
Ta = +30°C: 1.940 V typ.
Ta = +100°C: 1.145 V typ.
Nonlinearity ±0.5% typ. (-20°C to +80°C)
Wide power supply voltage operation VDD = 2.4 V to 10.0 V(+25°C)
Low current consumption 4.5 μA typ. (+25°C)
Built-in operational amplifier
VSS standard output
Lead-free, Sn 100%, halogen-free

Application

Compensation of high-frequency circuits such as cellular phones and radio equipment
Compensation of oscillation frequency in crystal oscillator
LCD contrast compensation
Compensation of amplifier gain
Compensation of auto focus circuits
Temperature detection in battery management
Overheating prevention for charged batteries or halogen lights

etCMD
eCMD_START

Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oS5813A_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) / ( 2^{AD bit} )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
3. Store Temperature to rlt.

Command API function :
etSTS oS5813A_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) / ( 2^{AD bit} )
Temperature = ((voltage value – voltage offset value) / gain) + Temperature offset value (Min, Max Limit)
5. Store Temperature to rlt.

Command API function :
etSTS oS5813A_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
