Parameter
in OTP
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.
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
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.
Incremental ABI interface: 3 pins
BLDC UWV interface: 3 pins
Absolute interface: 2 or 3 pins
All outputs are available at the same time on separate pins
30,000 rpm
+/- 0.25 mm (reference to package center)
Typ 14mA; max 22mA
≤1.3 ms from cold start (no AGC),
≤4.1ms from cold start (AGC locked)
<0.5ms from low power mode
