Abstract

This work presents a pair of low power high-voltage (HV) transmitters for battery management systems (BMS). Besides, the HV transmitter is designed using CMOS transistors without any isolator. To realize a solution on silicon, the proposed HV Transmitter shall be fabricated using an advanced HV semiconductor process, which usually is constrained by the voltage drop limitation between gate and source of HV devices. The proposed design is implemented using a typical 0.25 μm 1-poly 3-metal 60 V BCD process. The post-layout simulation results show that the HV transmitters can transmit data with HV dc level (36.4 ~ 54.6 V) and the power consumption is less than 0.342 mW/Mbps.
