TPSI3050Q1EVM EVM (Evaluation Module) helps designers evaluate the operation and performance of the isolated switch driver, TPSI3050-Q1. This user's guide provides the connectors, test point descriptions, operational modes, schematic, bill of materials, and board layout of the EVM. The TPSI3050-Q1 is a 5-kVRMS reinforced isolated switch driver with 1.5-A peak source current and 3-A peak sink current. The device is able to generate a regulated secondary power supply of 10 V. This regulated power supply allows for a wide selection of MOSFETs or SCRs. The EVM includes two back-to-back 650-V and 42-A NMOS with D2PAK package for easy testing and footprint for one SCR with a TO247-3 package. The inputs and outputs connections to the board are terminal blocks, which allow for easy wired connections. The EVM is rated for a load up to 500-VDC/350-VRMS and 4 A. The board contains multiple test points to monitor the TPSI3050-Q1 functionality. In addition, the EVM contains a 3.3-V LDO to supply VDDP from a battery to the input of the TPSI3050-Q1 with an output of 3.3 V. The EVM allows the user to test multiple applications, such as AC/DC Solid State Relay (SSR), battery management, and precharge circuits.

Always follow TI's set-up and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure your personal safety and those working around you. Contact TI's Product Information Center http://ti.com/customer support for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions may result in personal injury, property damage or death due to electrical shock and burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise and knowledge of electrical safety risks in development and application of high voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas Instruments. If you are not suitably qualified, you should immediately stop from further use of the HV EVM.
As a precautionary measure, it is always good engineering practice to assume that the entire EVM may have fully accessible and active high voltages.
While the EVM is energized, never touch the EVM or its electrical circuits, as they could be at high voltages capable of causing electrical shock hazard.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.
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.
