Fig 4. Equivalent output circuit in case of a power-loss condition

Table 4 describes the power-loss behavior and gives the resulting output voltage

depending on the interrupted supply or ground line and the load resistance.

7.4 Broken bond wire detection

The broken bond wire detection circuit enables the detection of an interrupted supply or

ground line of the MR sensor bridge. In the case of a broken bond wire the device goes

into diagnostic mode and a status bit is set.

7.5 Low supply voltage detection and overvoltage protection

If the supply voltage is below the switch-off threshold voltage, a status bit is set and the

device goes into diagnostic mode. If the supply voltage is above the overvoltage switch-on

threshold voltage, the device enters diagnostic mode. Table 5 describes the system

behavior depending on the voltage range of the supply voltage.

start-up power The output buffer drives an active LOW or is powered down,

but the switches of the power-loss detection circuit are not

fully opened and set the output to a level between ground and

half the supply voltage.

power-on

reset

The power-loss charge pump is fully operational and turns the

switches of the detection circuit off. The output buffer drives

an active LOW and sets the output to the lower diagnostic

level. During the reset phase all circuits are in reset and/or

Power-down mode.

V_PORto V_th(on)or initialization

V_th(off)

The digital core and the oscillator are active. After reset the

content of the non-volatile memory is copied into the shadow

registers. The output buffer drives an active LOW and sets the

output to the lower diagnostic level.

V_th(on)or V_th(off)to functional

All analog circuits are active and the measured angle is

available at the analog output. Not all parameters are within

the specified limits.
