1.3. Marking Code
The HAL 283x have a marking on the package surface
(branded side). This marking includes the name of the
sensor and the temperature range.

1.4. Operating Junction Temperature Range (TJ)
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature range TJ).
A: TJ = −40 °C to +170 °C
K: TJ = −40 °C to +140 °C
The relationship between ambient temperature (TA)
and junction temperature is explained in Section 6.1.

1.6. Solderability and Welding
Solderability
During soldering reflow processing and manual
reworking, a component body temperature of 260 °C
should not be exceeded.
Welding
Device terminals should be compatible with laser and
resistance welding. Please note that the success of
the welding process is subject to different welding
parameters which will vary according to the welding
technique used. A very close control of the welding
parameters is absolutely necessary in order to reach
satisfying results. Micronas, therefore, does not give
any implied or express warranty as to the ability to
weld the component.

2) A resolution of 12-bit is guaranteed only.
Magnetic Offset D
The D (offset) registers contain the parameter for the
adder in the DSP. The added value is a first order poly-
nomial of the temperature.
