6.3 Power-lost detection
6.4 Low supply voltage detection
The power-lost detection circuits enable the detection of an interrupted supply or ground
line of the KMA199E. In case of a power-lost condition, two internal switches within the
sensor are closed, connecting the pin of the analog output with the pins of the supply
voltage and the ground.

Table 3.
If the supply voltage is below the switch-off threshold voltage, a status bit is set.
Following table describes the behavior of the analog output at different supply voltages.

Description
the output drives an active LOW, but the
switches of the power-lost detection circuits
are not fully opened and set the output to a
level between ground and half the supply
voltage
all modules begin to work and the power-on
reset is active
all modules begin to work and the digital part
is initialized
analog output is switched on after power-on
time and represents the measured angle
normal operation where the sensor works with
the specified accuracy
