1 Introduction

The growing electric vehicle (EV) market and trends towards higher voltage, smaller battery packs with increased power density, necessitates a safer, more reliable, design for High Voltage (HV) measurement. The increasing number of HV measurement sockets in modern Battery Management Systems (BMS) warrants the need for an alternative to current discrete designs because of the large size, reliability problems associated with exposed nodes, and high part count. Compared to existing discrete resistor divider designs for HV measurement, TI's cutting-edge integrated HV divider technology results in a smaller design with a precise resistor ratio and longer lifetime, all while achieving cost parity. Additionally, modern BMS requirements for improved quality and control are addressed with a smaller part count, eliminating complicated Bill of Materials (BOMs) and saving time during development, especially between EV platforms. The TPS4141-Q1 or RES60A-Q1 are fit to deliver all the advantages of an integrated design compared to legacy discrete designs in the areas of Scalability, Safety, and Reliability.
