5.4. Ambient Temperature
Due to internal power dissipation, the temperature on
the silicon chip (junction temperature T
J
) is higher than
the temperature outside the package (ambient tempera-
ture T
A
).

At static conditions and continuous operation, the follow-
ing equation is valid:
T = I

For all sensors, the junction temperature range T
J
is
specified. The maximum ambient temperature T
Amax
can be calculated as:

For typical values, use the typical parameters. For worst
case calculation, use the max. parameters for I

, and the max. value for V

Due to the range of I
DDhigh
, self-heating can be critical.
The junction temperature can be reduced with pulsed
supply voltage. For supply times (t

) ranging from 30
μ

to 1 ms, the following equation can be used:

5.5. EMC and ESD
For applications with disturbances on the supply line or
radiated disturbances, a series resistor and a capacitor
are recommended (see Fig. 5–2). The series resistor
and the capacitor should be placed as closely as pos-
sible to the HAL sensor.
Please contact Micronas for detailed information and
first EMC and ESD results.
