MPXHZ6250A

MPXHZ6250A is a pressure sensor IC (20 kPa to 250 kPa) made by NXP Semiconductors. This posting will provide the OSS-ECAL(Open Source Software for Electronic Components Abstraction Layer) for MPXHZ6250A.
MCU interface : ADC

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

MPXHZ6250A

General description

The Freescale MPXHZ6250A series sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high output signal and temperature compensation. The small form factor and high reliability of on-chip integration make the Freescale sensor a logical and economical choice for automotive system designers.
The MPXHZ6250A series piezoresistive transducer is a state-of-the-art, monolithic, signal conditioned, silicon pressure sensor. This sensor combines advanced micromachining techniques, thin film metallization, and bipolar semiconductor processing to provide an accurate, high level analog output signal that is proportional to applied pressure.

Feature
  • Improved Accuracy at High Temperature
  • Available in Small and Super Small Outline Packages
  • 1.5% Maximum Error over 0° to 85°C
  • Ideally suited for Microprocessor or Microcontroller-Based Systems
  • Temperature Compensated from ñ40° to +125°C
  • Durable Thermoplastic (PPS) Surface Mount Package
Application
  • Industrial Controls
  • Engine Control/Liquified Petroleum Gas (LPG)

etCMD
eCMD_START


Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oMPXHZ6250A_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 Pressure, and stores the Pressure in rlt.

Process :
1. Read AD conversion value.
2. Convert AD conversion value to Pressure.
Voltage value = (AD conversion value × VDD) / (2AD bit )
Pressure = ((voltage value – voltage offset value) / gain) + Pressure offset value (Min, Max Limit)
3. Store Pressure to rlt.

Command API function :
etSTS oMPXHZ6250A_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 Pressure, and stores the Pressure in rlt.

Process :
1. Read AD conversion value.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Pressure.
Voltage value = (AD conversion value × VDD) / (2AD bit )
Pressure = ((voltage value – voltage offset value) / gain) + Pressure offset value (Min, Max Limit)
5. Store Pressure to rlt.

Command API function :
etSTS oMPXHZ6250A_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
