[AK9750]
On initial power-on with PDN pin= “H”, AK9750 is in Stand-by Mode. Based on EMODE [2:0] setup, the
AK9750 shifts to the selected Mode, and starts operating. Any Mode changing should be done via
Stand-by Mode.
11.3.3. Switch Mode
There are two Modes in Switch Mode.
<Switch Mode (CAD0 pin= CAD1 pin= “H”)>
(1) Power down Mode
(2) Measurement Mode
Power down Mode:
The all Circuits are powered down for decreasing the current consumption.
PDN= “H”
PDN= “L”
Measurement Mode:
Measurement is automatically repeated. The measurement is done in the conditions which are set to
the EEPROM beforehand.
The measurement conditions should be set to the EEPROM in the customer’s mass production line.
