AS5403A/D/E − Device Configuration

Protections

When the voltage applied to the VDD pin falls below the

undervoltage lower threshold (VDDUVTL) for longer than the

TVDDUVDET time the device stops the clock of the digital part,

it resets the EEPROM signature calculation and the 3D Hall core

and the output drivers are turned off to reduce the power

consumption. When the voltage applied to the VDD pin exceeds

the VDD undervoltage upper threshold (VDDUVTH) for longer

than the TVDDUVREC time the clock, the signature calculation

and the 3D Hall core are restarted and the output drivers are

turned ON.
