Note: Pin 1 (MagINCn) and pin 2 (MagDECn) are active low via open drain output and require an external pull-up
resistor. If the magnetic field is in range, both outputs are turned off.
The two pins may also be combined with a single pull-up resistor. In this case, the signal is high when the magnetic
field is in range. It is low in all other cases (see Table 4 and Table 5 ).
8.2 Daisy Chain Mode
The Daisy Chain mode allows connection of several AS5045’s in series, while still keeping just one digital input for
data transfer (see “Data IN” in Figure 6 below). This mode is accomplished by connecting the data output (DO; pin 9)
to the data input (PROG; pin 8) of the subsequent device. An RC filter must be implemented between each PROG
pin of device n and DO pin of device n+1, to prevent then encoders to enter the alignment mode, in case of ESD
discharge, long cables, not conform signal levels or shape. Using the values R=100R and C=1nF allow a max. CLK
frequency of 1MHz on the whole chain. The serial data of all connected devices is read from the DO pin of the first
device in the chain. The length of the serial bit stream increases with every connected device, it is
n * (18+1) bits:
e.g. 38 bit for two devices, 57 bit for three devices, etc…
The last data bit of the first device (Parity) is followed by a dummy bit and the first data bit of the second device
(D11), etc… (see Figure 7 )
