Multiturn Counter

8-bit (+127/-128 turns). Optional: >8-bit (tbd)

Automatically updated during active mode at every 360º-/0º-

transition in each rotating direction.

The multiturn counter can be accessed over the serial interface

and is reset with a power-on-reset.

It will be frozen at the last valid state in low power mode.

Low power mode

Non-operational. Last status is frozen in Low power mode to

allow low power consumption and fast startup from low power

mode to operating mode.

Serial interface is active in low power mode to allow wakeup

over the serial interface.

PWM, incremental and BLDC outputs are invalid in low power

mode, they remain at their last valid state.

Current consumption in low power mode: typ. 30µA

PWM output

2µs / step. 360º angle range in all modes.

Minimum pos. pulse width (@0º) = 16us (8 LSB; tbd)

Minimum neg. pulse width (@359º) = 16us (8 LSB; tbd)

Pulse width @0º = 16µs, Pause = 736µs

Pulse width @1º = 18µs, Pause = 734µs

Pulse width @2º = 20µs, Pause = 732µs

………..

Pulse width @359º = 736µs, Pause = 16µs

In case of an error (LOCK = Low), the pulse width is

8 µs (4 LSB), pause = 744µs for all angles.
