High Voltage Intelligent Battery Shunt Sensor with USB Interface

Selected

The HV-IBSS-USB is a reference design showcasing an isolated current and voltage measurement unit connected via USB-C. This design provides one current measurement channel and one voltage measurement channel. It also demonstrates the effectiveness of our WSBE low TCR battery shunt technology and our CDMA high-precision, low-tracing-error voltage divider in minimizing measurement variation with temperature changes. The HV-IBSS-USB can measure currents of up to ±500 A and voltages of up to ±1000 V. It streams high-resolution data to a virtual COM port at a low frequency.
