8.2. AC Characteristics
Power supply rise time
(Note 4)
Period of time that VDD changes
from 0.2V to Vdd.
POR completion time
(Note 4)
Period of time after PSUP to
Power-down mode (Note 5)
Power supply turn off
voltage (Note 4)
Turn off voltage to enable POR to
restart (Note 5)
Power supply turn on
interval (Note 4)
Period of time that voltage lower
than SDV needed to be kept to
enable POR to restart (Note 5)
Wait time before mode
setting
(Note 4) Reference value for design.
(Note 5) When POR circuit detects the rise of VDD voltage, it resets internal circuits and initializes the
registers. After reset, AK09918 transits to Power-down mode.
8.3. Analog Circuit Characteristics
Measurement data output bit
Magnetic sensor sensitivity
Magnetic sensor measurement range
(Note 6)
Magnetic sensor initial offset
(Note 7)
(Note 6) Reference value for design
(Note 7) Value of measurement data register on shipment test without applying magnetic field on purpose.
