Abstract :

 

A voltage monitoring IC with high-voltage multiplexer (HVMUX) and HV Transceiver for Battery Management Systems (BMS) is demonstrated. The voltage monitoring IC in a BIM (battery interconnect module) must be able to accommodate input voltage up to tens of volts, perhaps even hundreds of volts, which is difficult to be realized using a logic-based solution. To realize a solution on silicon, the voltage monitoring IC shall be fabricated using an advanced HV semiconductor process, which usually is constrained bythe voltage drop limitation between gate and source of HV devices.  To overcome such a limitation, a HV switch is proposed in this work, including a HV Gate Voltage Driver (HVGVD) driving the HV MOS without any over-voltage hazard.  Besides, a HV Transceiver is proposed using standard CMOS transistors without any isolator.
