## **AUTOMOTIVE CURRENT TRANSDUCER OPEN LOOP TECHNOLOGY DHAB S/125** 

## ~~**Introduction**~~ 

The DHAB family is best suited for DC, AC, or pulsed currents measurement in high power and low voltage automotive applications. It features g ~~alvanic separation~~ between the primary circuit (high power) and ~~th~~ e sec ~~on~~ dary ci ~~r~~ cuit (electronic circuit). 

The DH ~~AB famil~~ y gives you a choice of ~~h~~ aving different current measuri ~~ng~~ ranges in the same housing ~~(~~ from ±20 up to ±900 A). 

## ~~**Features**~~ 

- ●Open Loop transducer using the Hall effect 

- ●Low voltage application 

- ~~●U~~ nip ~~o~~ lar ~~+~~ 5 V ~~DC~~ power supply 

- ~~P~~ rim ~~a~~ ry c ~~u~~ rrent ~~me~~ asu ~~r~~ i ~~n~~ g range up to ±25 A for channel 1 an ~~d~~ ±20 ~~0~~ A f ~~o~~ r channel 2 

- ●M ~~a~~ ximu ~~m~~ RMS ~~p~~ rimary admissible current: defined by busbar to have _T_ ° < + ~~1~~ 50 ~~°C~~ 

- ~~O~~ perating temperatu ~~r~~ e rang ~~e~~ : −40 °C < _T_ ° < +125 °C 

- ~~●Output voltage: full ratio-metric (in sensitiv~~ ity and offset). 

## ~~**Special feature**~~ 

- ●Dual channel transducer for wider measurement range and redundancy. 

## ~~**Automotive applications**~~ 

- ●Battery Pack Monitoring 

- ●Hybrid Vehicles 

- ●EV and Utility Vehicles. 

## ~~**Principle of DHAB 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 _I_ P to be measured. The current to be measured _I_ P is supplied by a current source i.e. battery or generator (Figure 1). 

Within the linear region of the hysteresis cycle, _B_ is proportional to: 

**==> picture [53 x 11] intentionally omitted <==**

The Hall voltage is thus expressed by: 

**==> picture [111 x 11] intentionally omitted <==**

Except for _I_ P, all terms of this equation are constant. Therefore: 

_U_ Hall = _b_ × _I_ P _a_ constant _b_ constant _c_ Hall Hall coefficient _d_ thickness of the Hall plate _I_ Hall current across Hall plates 

The measurement signal _U_ Hall is amplified to supply the user output voltage or current. 

## ~~**Advantages**~~ 

- ●Good accuracy for high and low current range 

- ●Good linearity 

- ●Low thermal offset drift 

- ●Low thermal sensitivity drift 

- ●Hermetic package.

U out Primary current nominal ( I P N)<br>Primary current, measuring range ( I P M)<br>I P<br>**----- End of picture text -----**<br>


## **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 part of a statistical distribution that can be specified by an interval with 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 for values 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 obviously mean or average values, those values are defined to delimit intervals with a probability of 68.27 %, corresponding to an interval 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:** 

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

## **Magnetic offset:** 

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

## **Linearity:** 

The maximum positive or negative discrepancy with a reference straight line _U_ out = _f_ ( _I_ P). 

Unit: linearity (%) expressed with full scale of _I_ P N.

## **Sensitivity:** 

The transducer’s sensitivity _S_ is the slope of the straight line _U_ out = _f_ ( _I_ P), it must establish the relation: 

_U_ out ( _I_ P) = _U_ C/5 ( _S_ × _I_ P + _U_ O) 

## **Offset with temperature:** 

The error of the offset in the operating temperature is the variation of the offset in the temperature considered with the initial offset at 25 °C. 

The offset variation _I_ O _T_ is a maximum variation the offset in the temperature range: 

_I_ O _T_ = _I_ O E max − _I_ O E min 

The offset drift _TCI_ O E AV is the _I_ O _T_ value divided by the temperature range. 

## **Sensitivity with temperature:** 

The error of the sensitivity in the operating temperature is the relative variation of sensitivity with the temperature considered with the initial offset at 25 °C. 

The average temperature coefficient of sensitivity _TCS_ AV, _S T_ is the maximum temperature variation of _S_ (in ppm or %) of the sensitivity in the temperature range: 

_ST_ = (Sensitivity max − Sensitivity min) / Sensitivity at 25 °C. The average temperature coefficient of sensitivity _TCS_ AV is the 

_ST_ value divided by the temperature range. Deeper and detailed info available is our LEM technical sales offices (www.lem.com). 

## _I_ **= 0 A: Offset voltage @** P 

The offset voltage is the output voltage when the primary current is zero. The ideal value of _U_ O is _U_ C/2. So, the difference of _U_ can be attributed to the electrical offset (due to the resolution of O − _U_ C/2 is called the total offset voltage error. This offset error the ASIC quiescent voltage trimming), the magnetic offset, the thermal drift and the thermal hysteresis. Deeper and detailed info available is our LEM technical sales offices (www.lem. com).
