AS5043
Data Sheet – Failure Diagnostics
17 Failure Diagnostics
The AS5043 also offers several diagnostic and failure detection features:
17.1 Magnetic Field Strength Diagnosis
By software: the MagInc and MagDec status bits will both be high when the magnetic field is out of range.
By hardware: Pin #1 (MagRngn) is a logical NAND-ed combination of the MagInc and MagDec status bits. It is an open-
drain output and will be turned on (= low with external pull-up resistor) when the magnetic field is out of range.
By hardware: Pin #12 (Vout) is the analog output of the DAC and OP-Amp. The analog output will be 0V, when the
magnetic field is out of range (all analog modes).
17.2 Power Supply Failure Detection
By software: If the power supply to the AS5043 is interrupted, the digital data read by the SSI will be all “0”s. Data is only
valid, when bit OCF is high, hence a data stream with all “0”s is invalid. To ensure adequate low levels in the failure case,
a pull-down resistor (~10k Ω ) should be added between pin DO and VSS at the receiving side
By hardware: The MagRngn pin is an open drain output and requires an external pull-up resistor. In normal operation,
this pin is high ohmic and the output is high. In a failure case, either when the magnetic field is out of range or the power
supply is missing, this output will become low. To ensure an adequate low level in case of a broken power supply to the
AS5043, the pull-up resistor (~10k Ω ) must be connected to the positive supply at pin 16 (VDD5V).
