Preliminary Technical Data
ADuC7032
ADUC7032 ON-CHIP DIAGNOSTICS
The ADuC7032 integrates multiple diagnostic support circuits on-chip. These circuits allow the device to test core digital functionality,
analog front-end and high-voltage I/O ports in-circuit.
ADC Diagnostics
Internal Test Voltage
The current channel can be configured to convert on an internal 8.3mV test voltage . On any gain range the result should be within
±0.5% of the expected result.
Internal Short Mode
The current and voltage input channels can also be shorted internally. Converting on the internal short will allow an assessment of the
internal ADC noise to be determined.
Internal Current Sources
Internal current sources can also be enabled on both current and temperature channels. These current sources can be used to determine
external short or open circuit conditions in both external shunt or temperature sensor configurations.
High Voltage I/O Diagnostics
High Voltage I/O Read back
All high voltage I/O pins are supported with read back capability. This allows the detection of external short conditions.
High Voltage Current Detection
All high voltage I/O pins also have a high current detection capability allowing high side connections to VBAT to be detected and
controlled.
