Description

MagRngn

DO_T

Push-Pull output. Is HIGH when the magnetic field strength is too weak, e.g. due

to missing magnet

Prog_DI

OTP Programming voltage supply pin. Leave open or connect to VDD if not used

VSS

Supply ground

T3_SINn

This pin is used for factory testing. For normal operation it must be left

unconnected. Inverse SIN (Sinn) output in SIN/COS output mode

T2_SIN

This pin is used for factory testing. For normal operation it must be left

unconnected. SIN output in SIN/COS mode

T1_COSn

This pin is used for factory testing. For normal operation it must be left

unconnected. Inverse COS (Cosn) output in SIN/COS mode

T0_COS

This pin is used for factory testing. For normal operation it must be left

unconnected. COS output in SIN/COS mode

Test pin. Connect to VSS or leave unconnected

Digital output for 2-wire operation and Daisy Chain mode

CLK

DI_ST

Clock Input of Synchronous Serial Interface; Schmitt-Trigger input

DI_ST

Chip Select for serial data transmission, active high; Schmitt-Trigger input,

external pull-down resistor (~50k

Ω) required in read-only mode

DIO

Data output / command input for digital serial interface

VDD

Positive supply voltage, 4.5V to 5.5V

Configuration input: connect to VSS for normal operation,

connect to VDD to enable SIN-COS outputs. This pin is scanned at power-on-reset

and at wakeup from one of the Ultra Low Power Modes

Configuration input: connect to VSS for 3-wire operation,

connect to VDD for 2-wire operation. This pin is scanned at power-on-reset and at

wakeup from one of the Ultra Low Power Modes

PWM

Pulse Width Modulation output, 2µs pulse width per step (2µs ~ 512µs)
