Description

CAO

Indicates if the magnetic field is present. If the field is too low, the signal is HI.

PROG

OTP Programming Pad, programming voltage. For normal operation it must be left

unconnected.

VSS

Supply Ground.

SINP

Used for factory testing. For normal operation it must be left unconnected.

SINN

Used for factory testing. For normal operation it must be left unconnected.

COSP

Used for factory testing. For normal operation it must be left unconnected.

COSN

Used for factory testing. For normal operation it must be left unconnected.

Test Coil

Test pin. Must be left unconnected.

DCLK

Clock Source for SSI communication. Schmitt trigger input.

Chip Select for SSI. Active high. Schmitt trigger input.

DIO

Data input / output for SSI communication.

VDD

Positive Supply Voltage 5V.

Test mode selector. For normal operation it must be connected to VSS.

WAKE

Interrupt output. Used for polling mode. Open Drain NMOS. Use pull-up resistor with

>1.5k

Ω.

PWM

Pulse Width Modulation output. 0.5µs width step per LSB.

DVDD

Pin to connect to low power supply for polling mode. Must be connected to VSS in normal

mode.
