1.3. Marking Code

The HAL856 has 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 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 4.4.

on page 31.

1.5. Hall Sensor Package Codes

Example: HAL856UT-K

→ Type: 856

→ Package: TO92UT

→ Temperature Range: T

J = −40°C to +140°C

Hall sensors are available in a wide variety of packag-

ing versions and quantities. For more detailed informa-

tion, please refer to the brochure: “Micronas Hall Sen-

sors: Ordering Codes, Packaging, Handling”.

1.6. Solderability and Welding

Soldering

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.

1.7. Pin Connections and Short Descriptions

Note: Pin 3 is only active before locking of the sensor.

It can be used for the communication with the

sensor before the EEPROM is locked.

Fig. 1–1: Pin configuration

Note: The third sensor pin should be floating or con-

nected to the GND line after locking the sensor.
