AS5045B

Datasheet - Application In form atio n

- CCW: Counter Clockwise Bit

ccw=0 – angular value increases in clockwise direction

ccw=1 – angular value increases in counterclockwise direction

- RA [4:0]: Redundant Address: an OTP bit location addressed by this address is always set to “1” independent of the corresponding

original OTP bit setting

9.1.4 OTP Default Setting

The AS5045B can also be operated without programming. The default, un-programmed setting is:

- Z0 to Z11: 00 = no programmed zero position

- CCW: 0 = clockwise operation

- RA4 to RA0:0 = no OTP bit is selected

- MagCompEN: 1 = The green/yellow Mode is enabled

9.1.5 Redundancy

For a better programming reliability a redundancy is implemented. In case when the programming of one bit failed this function can be used. With

an address RA(4:0) one bit can be selected and programmed.
