Type
Description
S
Supply ground
S
Positive supply voltage, 4.5V to 5.5V
DI_ST
Clock Input of Synchronous Serial Interface; Schmitt-Trigger input
Chip Select for serial data transmission, active high; Schmitt-Trigger input,
DI_ST
external pull-down resistor (~50kΩ) required in read-only mode
DIO
Data output / command input for digital serial interface
DI
Command input for digital serial interface. Connect to GND if not used.
S
OTP Programming voltage supply pin. Leave open or connect to VDD if not used
S
Supply ground
S
Positive supply voltage, 4.5V to 5.5V
-
0~5V analog output. Generated by the PWM output and filtered.
DO
Digital output for 2-wire operation and Daisy Chain mode
DO
Pulse Width Modulation output, 2.26µs pulse width per step (2.26µs ~ 512µs)
Push-Pull output. Is HIGH when the magnetic field strength is too weak, e.g. due to missing
DO_T
magnet
S
Supply ground
-
Must be left unconnected for normal operation. COS output in SIN/COS mode (P1 open)
-
Must be left unconnected for normal operation. COSn output in SIN/COS mode (P1 open)
-
Must be left unconnected for normal operation. SIN output in SIN/COS mode (P1 open)
-
Must be left unconnected for normal operation. SINn output in SIN/COS mode (P1 open)
S
Supply ground
Configuration input for Sin/Cos output:
-
Connect to VSS for normal operation (P1 closed, by default)
DI
-
High level (P1 open) 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 for serial wire mode:
-
Connect to VSS for 3-wire operation (P2 closed, by default)
DI
-
High level (P2 open) for 2-wire operation
This pin is scanned at power-on-reset and at wakeup from one of the Ultra Low Power Modes
