3 AS5030 Parameter and Features List

Parameter

Description

Supply Voltage

5V ± 10%

Supply Current

Low Power Mode, non-operational: typ. 1.4mA

Ultra Low Power Mode, non-operational: typ. 30µA

Normal operating mode: typ. 14mA.

Absolute Output; Serial

Interface

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)

SSI Clock rate

≤ 6 MHz data clock rate, 250 ~ 500kHz during programming

2-wire Readout Mode

DIO and CLK signals. 0.1 ~ 6MHz clock rate. Synchronization through time-out of CLK

signal.

Power Down Modes

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

Digital input cells

CLK, CS = Schmitt trigger inputs

SIN-COS mode

Sine, inverse Sine, Cosine and inverse Cosine outputs. 360° per period.

Maximum Speed

30,000 rpm with locked ADC

Resolution and Accuracy

Resolution = 8 bit (1.406°)

Accuracy

≤ ± 2° with centered magnet

Transition Noise

0.24°rms (1 sigma)

PWM output

2.26µs / Step, PWM will be permanently low when angular data is not valid (e.g during

startup).

Digital Output Current

4mA @ VDD = 5V (PWM, DIO, DX, MagRngn outputs)

OTP programming mode

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

Magnetic Field Range

Trimable in four steps with OTP programming (sensitivity)

maximum/minimum ratio ~ 2.5:1. Field range window = 20 ~ 80mT

(e.g. maximum sensitivity range = 20 ~ 48mT, minimum sensitivity range = 32 ~ 80mT

Non-Valid-Range

indication

by hardware: MagRngn pin indicates locked condition of ADC

by software: LOCK1&2 status bits indicate locked condition of ADC

Start upTimings

Start-up time after shutdown < 2ms

Start-up time after power-down from Ultra Low Power Mode : < 500µs

Start-up time after power-down from Low Power Mode : < 150µs

ESD protection

± 2kV

Operating Temperature

-40°C ~ +125 °C
