Test output in default mode
Test output in default mode
For internal use. Must be left unconnected
Select between slow (open, low: VSS) and fast (high) mode. Internal pull-
down resistor. Hard wired connection to VDD or GND recommended.
Negative Supply Voltage (GND)
OTP Programming Input and Data Input for Daisy Chain mode.
Internal pull-down resistor (74kΩ). Should be connected to VSS if
programming is not used.
Clock Input of Synchronous Serial Interface; Schmitt-Trigger input
Data Output of Synchronous Serial Interface
Chip Select. Active low. Schmitt-Trigger input, internal pull-up resistor
(50kΩ)
Pulse Width Modulation
For internal use. Must be left unconnected
For internal use. Must be left unconnected
3V-Regulator Output for internal core, regulated from VDD5V. Connect to
VDD5V for 3V supply voltage. Do not load externally.
Positive Supply Voltage, 3.0V to 5.5V
Magnet Field Magnitude Increase. Active low. Indicates a distance
reduction between the magnet and the device surface.
Magnet Field Magnitude Decrease. Active low. Indicates a distance
increase between the device and the magnet.
