Datasheet - Detailed Description
7.8.3 Polling Mode
Target of this mode is a reduction of the average power consumption. In this mode, the IC supply is pulsed, thereby reducing the average power
consumption to a fraction. The actual angle information and multi turn count value is not lost; polling mode is especially suited for battery
powered applications. The IC is furthermore capable of generating a WAKE signal as soon as the magnets position has changed, but only if the
supply of the IC is powered-on again. By means of the WAKE signal, the systems power consumption can be further decreased, if certain
modules are activated on demand.
Figure 18. External Circuitry for Polling Mode
The voltage at pin 16 (DVDD) determines whether polling mode is activated or not. Any voltage above 3.6V activates the polling functionality.
This voltage must always be present at DVDD in order to hold the information in the registers.
The procedure is as follows:
1. Initial startup: The circuit starts up with invalid trim values, which are read back from the storage registers; the command rst_otp
(command 19 10011) must be sent to read out valid trim values from the OTP.
2. These values are copied to the storage registers if OTP<8> (Wake enable) is set (must be set for polling mode).
3. The values of AGC counter, actual angle, multi turn counter, hysteresis setting, wake threshold and gain setting are continuously
updated in the storage registers.
4. The actual angle is stored as a reference by sending command STORE REF (command 3 00011). without this reference angle, a
WAKE is generated at every startup.
5. The update of the storage registers is stopped if VDD drops below 4.45V and then the information is stored (DVDD) at the next startup
(VDD on), the values are read back from the storage registers and the measured angle is compared with the stored reference angle; if
the difference between both exceeds the threshold, a WAKE pulse is generated.
