100A Car Battery Management Open Loop Transducer HAH1BVW S/01

1.Introduction

The HAH1BVW family is for the electronic measurement of DC, AC or pulsed currents in high power and low voltage automotiveapplications with galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit).
The HAH1BVW family gives you the choice of having different current measuring ranges in the same housing

5.Principle of HAH1BVW 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 proportional to:B (IP) = a × IPThe Hall voltage is thus expressed by:VH = (cH /d) × IH × a × I

Except for IP, all terms of this equation are constant.Therefore:VH = b × IPaconstantb constantcHHall coefficientdthickness of the Hall plateIHcurrent across the Hall platesThe measurement signal VH amplified to supply the user output voltage or current.
