1 Introduction

The TPSI3050-Q1 is a fully integrated isolated switch driver, that when combined with an external power switch, forms a complete isolated solid state relay solution. The TPSI3050-Q1 is designed for automotive and industrial applications such as battery management systems, EV/HEV on-board chargers, replacing mechanical relays with SSR, DC link pre-charging, and more. The TPSI3050-Q1 seamlessly replaces relays without need for a secondary side supply while leveraging unique isolation technology integrated in a compact SOIC package. The TPSI3050-Q1 integrated isolation protection is extremely robust with much higher reliability, lower power consumption, and increased temperature ranges than those found using traditional mechanical relays and optocouplers.
