| Description | The TPSI2140QDWQRQ1 is a high-voltage isolated solid-state relay (SSR) developed by Texas Instruments, designed for automotive and industrial applications requiring reliable switching across isolation barriers. It integrates capacitive isolation technology with back-to-back MOSFETs, eliminating the need for external driver circuits or secondary-side power supplies. This device supports a high standoff voltage of up to ±1200V and can switch load currents up to 50mA, making it ideal for high-voltage measurement, insulation monitoring, and battery management systems. The TPSI2140QDWQRQ1 operates with a primary-side supply voltage range of 4.5V to 20V and requires only about 9mA operating current, enabling efficient control from standard microcontroller GPIO interfaces. Its architecture includes fail-safe enable (EN) control, ensuring that the device cannot unintentionally back-power the system, improving safety and reliability in critical applications. The fully integrated design reduces component count and simplifies PCB layout compared to traditional optocoupler or mechanical relay solutions. The device features automotive-grade AEC-Q100 qualification and operates over a wide temperature range of -40°C to +125°C, making it suitable for harsh environments such as EV systems and industrial equipment. Designed with robustness in mind, the TPSI2140QDWQRQ1 includes avalanche-rated MOSFETs capable of handling transient conditions and supporting dielectric withstand testing without additional protection components. Encapsulated in a compact 11-pin wide-body SOIC surface-mount package, the device ensures high isolation performance while enabling efficient PCB integration. The TPSI2140QDWQRQ1 is widely used in electric vehicle battery systems, insulation monitoring, high-voltage measurement equipment, solar inverters, and industrial power systems, where safe, reliable, and compact high-voltage switching is required. |
