HAL856 Datasheet, PDF (40/42 Pages) Micronas – Programmable Linear Hall-Effect Sensor with Arbitrary Output Characteristic (2-Wire)

HAL 856
DATA SHEET
SPECIAL CUSTOMER
– The register range is from 0 to 63 and contains the
settings for OUTPUT BITTIME and PARTNUMBER
ENABLE:
SPECIAL CUSTOMER = PARTNUMBER ENABLE ×
16 + OUTPUT BITTIME
Note: When output format PWM is used the default
values for the PARTNUMBER ENABLE bit must
not be modified:
HAL856: PARTNUMBER ENABLE = 0
DEACTIVATE
This register can only be written.
– The register has to be written with 2063 decimal
(80F hexadecimal) for the deactivation.
– The sensor can be reset with an Activate pulse on
the output pin or by switching off and on the supply
voltage.
