AUTOMOTIVE CURRENT TRANSDUCER OPEN LOOP TECHNOLOGYHSNDR 1000-S05*Introduction

Automotive application

The HSNDR series is for the electronic measurement of DC,
AC or pulsed currents in high power and low voltage automotive
applications with galvanic separation between the primarycircuit (high power) and the secondary circuit (electronic circuit).
The HSNDR series gives you the choice of having different
current measuring ranges in the same housing.

● Starter generatorsFeatures● Ratiometric transducer● Open Loop transducer using the Hall effect● Low voltage application● Unipolar +5 V DC power supply● Maximum RMS primary admissible current: defined bybusbar to have T < +150 °C● Operating temperature range: −40 °C < T < 125 °C● Output voltage: full ratio-metric (in sensitivity and offset).

Special feature● Inverters● EV applications● DC/DC converter.

Principle of HSNDR Family
The open loop transducers uses a Hall effect integrated circuit.
The magnetic flux density B, contributing to the rise of the Hall
voltage, is generated by the primary current IP to be measured.
The current to be measured IP is supplied by a current source
i.e. battery or generator (Figure 1).
Within the linear region of the hysteresis cycle, B is proportionalto:
B (IP) = a × IP

The Hall voltage is thus expressed by:

UHall = (cHall / d) × IHall × a × IP

Except for IP, all terms of this equation are constant.
Therefore:● Busbar uses passivation technology.

UHall = b × IPaconstantbconstant
cHall
Hall coefficient
dthickness of the Hall plate
IHall
current across the Hall plates

Advantages● Excellent accuracy● Very good linearity● High frequency bandwith

The measurement signal UHall amplified to supply the user
output voltage or current.

● Very fast response time
● Very low thermal offset drift● Very low thermal sensitivity drift● Galvanic separation● Non intrusive solution.

Definition of typical, minimum and maximum values:
Minimum and maximum values for specified limiting and safety
conditions have to be understood as such as values shown in“typical” graphs. On the other hand, measured values are partof a statistical distribution that can be specified by an intervalwith upper and lower limits and a probability for measured
values to lie within this interval. Unless otherwise stated(e.g. “100 % tested”), the LEM definition for such intervals
designated with “min” and “max” is that the probability forvalues of samples to lie in this interval is 99.73 %. For a normal(Gaussian) distribution, this corresponds to an interval between−3 sigma and +3 sigma. If “typical” values are not obviouslymean or average values, those values are defined to delimit
intervals with a probability of 68.27 %, corresponding to aninterval between −sigma and +sigma for a normal distribution.
Typical, minimum and maximum values are determined during
the initial characterization of a product.

Output noise voltage:t [µs]

Sensitivity:
The transducer’s sensitivity S is the slope of the straight line
Uout = f (IP), it must establish the relation:
Uout (IP) = UC/ 5 (S × IP + UO)

Offset with temperature:
The error of the offset in the operating temperature is thevariation of the offset in the temperature considered with theinitial offset at 25 °C.
The offset variation IO T is a maximum variation the offset in thetemperature range:
IO T = IO E max − IO E min

The output voltage noise is the result of the noise floor of theHall elements and the linear amplifier.

The offset drift TCIO E AV is the IO T value divided by thetemperature range.

Magnetic offset:

Sensitivity with temperature:

The magnetic offset is the consequence of an any current on
the primary side. It’s defined after a stated excursion of primarycurrent.

Linearity:
The maximum positive or negative discrepancy with a reference
straight line Uout = f (IP).
Unit: linearity (%) expressed with full scale of IP N.
UoutThe error of the sensitivity in the operating temperature is therelative variation of sensitivity with the temperature consideredwith the initial offset at 25 °C.
The sensitivity variation ST is the maximum variation (inppm or %) of the sensitivity in the temperature range:
ST = (Sensitivity max − Sensitivity min) / Sensitivity at 25 °C.
The sensitivity drift TCSAV is the ST value divided by thetemperature range. Deeper and detailed info available is ourLEM technical sales offices (www.lem.com).

Non linearity example

Offset voltage @ IP = 0 A:
The offset voltage is the output voltage when the primary current

Referencestraight lineis zero. The ideal value of UO is UC/ 2. So, the difference ofMax linearity error

IPLinearity variation in IP N

UO − UC/ 2 is called the total offset voltage error. This offset error
can be attributed to the electrical offset (due to the resolution ofthe ASIC quiescent voltage trimming), the magnetic offset, thethermal drift and the thermal hysteresis. Deeper and detailed
info available is our LEM technical sales offices (www.lem.
com).

Recommendations for use:
Storage:

The LEM transducers must be stored in a dry location, within the following ambient room conditions (< 40 °C and < 60 % RH).
The product should be stored in its original packing. Ensure during storage and transport, the units are not damaged by applying excess weight to the packaging. The transducers must not be stored more than three months. Maximal stackup storage of
secondary container (pallet) must not exeed 2.
Unpacking:
When unpacking, care must be taken with cutting tools not to damage the transducer.
Handling:
The LEM transducers must be handled with care and not undergo any shocks or falls (fall = scrap). It is recommended to handle
the transducer as long as possible inside its original packing (thermoform tray on customer’s assembly station). It is forbidden tohandle the transducers by their terminals. To avoid problems of ESD, it is recommended not to touch secondary terminals. Any
rework operation are forbidden and will conduct part out of LEM warranty.
Installation:
The workshop and the people in contact with the transducers must be ESD protected. Before installing, be sure to check thatthe transducer corresponds to the required application. Be sure that the air gap between the housing of the transducer and theprimary bar is suffisant to avoid damage in case of vibrations.
LEM do not recommand customers to make any maintenance on LEM sensors otherwise, it will drive sensors directly out ofwarranty.
Concerning installation and re-installation , cauthougly care need to be taken for taped sensors same for screwed sensors.
Sensors fixed by clips must be scraped after any dismounting from the original locations.
