The Vishay Reference design high voltage intelligent battery shunt is designed to make evaluation of the WSBE8518 low TCR shunt easy. It uses a single USB C connector to provide power to the circuit and to emulate a serial interface so the user can conveniently read voltage current, and temperature readings. During the development of this reference design it became clear that the main challenge has become finding low thermal drift analogue parts, rather than compensating the resistive element. Versatile
Precise and accurate
Maximum 10 ppm per K drift due to shunt
Easy to connect to bus bar and lugs via M6 screws
Less than 0.2 percent factory two point current calibration
