Low Power Mode, non-operational: typ. 1.4mA
Ultra Low Power Mode, non-operational: typ. 30µA
Normal operating mode: typ. 14mA.
21-bit Synchronous Serial Interface (SSI): 5 command bits, 2 data valid bits, 6 data bits for magnetic
field strength, 8 data bits for angle.
Configurable for 2-wire (Clock, Data) or 3-wire (Chip Select, Clock, Data) operation
Daisy Chain mode for reading multiple encoders through a 2- or 3-wire interface.
Zero Position Programming (OTP)
≤ 6 MHz data clock rate, 250 ~ 500kHz during programming
DIO and CLK signals. 0.1 ~ 6MHz clock rate. Synchronization through time-out of CLK signal.
Activated and deactivated by software commands.
Low Power Mode: power down current = 1.4mA typ.; power up time <150µs
Ultra Low Power Mode: power down current = 30µA typ.; power up time <500µs
CLK, CS = Schmitt trigger inputs
Sine, inverse Sine, Cosine and inverse Cosine outputs. 360° per period.
30.000 rpm with locked ADC
Resolution = 8-bit (1.406°)
Accuracy ≤ ± 2° with centered magnet
0.24°rms (1 sigma)
2.26µs / Step, PWM will be permanently low when angular data is not valid (e.g. during startup).
4mA @ VDD = 5V (PWM, DIO, DX, MagRngn outputs)
Through serial interface with static programming voltage on pin #2 (PROG)
16-bit OTP programming register. OTP user programming options:
Angular zero position: 8 bit
Hall element sensitivity: 2 bit
Trimmable in four steps with OTP programming (sensitivity)
