www.ti.com User’s Guide TPSI3052Q1EVM Automotive Reinforced Isolated Switch Driver with Integrated 15-V Gate Supply EVM User’s Guide ABSTRACT TPSI3052Q1EVM EVM (Evaluation Module) helps designers evaluate the operation and performance of the isolated switch driver, TPSI3052-Q1. This user's guide provides the connectors, test point descriptions, operational modes, schematic, bill of materials, and board layout of the EVM. The TPSI3052-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 15 V. This regulated power supply allows for a wide selection of power switches, such as MOSFETs, IGBTs, and SiC. The EVM includes two back-to-back N-Channel 750-V 28A silicon carbide (SiC) MOSFET in a TO-247-3L 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 TPSI3052-Q1 functionality. In addition, the EVM contains an adjustable LDO to supply VDDP from a battery to the input of the TPSI3052-Q1 with an output of 5 V. The EVM allows the user to test multiple applications, such as AC/DC solid state relay (SSR), battery management, and precharge circuits. ! Caution Do not leave EVM powered when unattended !

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. WARNING 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. 1. Work Area Safety: a. Keep work area clean and orderly. b. Qualified observer(s) must be present anytime circuits are energized. c. Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages may be present, for the purpose of protecting inadvertent access. d. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related apparatus used in a development environment exceeding 50Vrms/75VDC must be electrically located within a protected Emergency Power Off EPO protected power strip. e. Use stable and non-conductive work surface. f. Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible. 2. Electrical Safety: a. As a precautionary measure, it is always good engineering practice to assume that the entire EVM may have fully accessible and active high voltages. b. De-energize the TI HV EVM and all its inputs, outputs and electrical loads before performing any electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely deenergized. c. With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment hook-ups and other application needs, while still assuming the EVM circuit and measuring instruments are electrically live. d. Once EVM readiness is complete, energize the EVM as intended.

The TPSI3052-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 TPSI3052-Q1 seamlessly replaces relays without need for a secondary side supply while leveraging unique isolation technology integrated in a compact SOIC package. The TPSI3052-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.

The EVM is designed with the flexibility to add Common Mode Chokes to minimize EMI. Figure 1-2 shows the functional block diagram for the isolated switch. The TPSI3052-Q1 is able to generate a floating secondary supply of 15 V with a 1.5-A peak source current and 3-A peak sink current. In addition, TPSI3052-Q1 supports two operation modes: two-wire and three-wire mode. In two-wire mode, the EN pin provides the power on the primary side. Use three-wire mode for applications that require higher levels of power transfer and the fastest enable and disable switch times the TPSI3052-Q1 can offer.

Two-Wire Mode Simplified Schematic In two-wire mode, the TPSI3052-Q1 can be controlled using two pins, EN and VSSP. When EN is greater or equal to 6.5 V, power is drive to the device. When the EN voltage is high, power gets delivered into the secondary side of the device. When EN is low, then power transfer into the secondary side stops and the MOSFETs or SCRs turns off. To configure the EVM for two-wire mode, the following changes must be made: 1. Remove J2-Header. Leave VDDP floating with Cin to VSSP. 2. Supply the EN voltage using the terminal block J1.

MOSFET configurations: a. Figure 4-1 shows an application using two back-to-back common source MOSFETs. By connecting the load between terminals SW1-SW2, the user can load the EVM with an AC or a DC load. By using two back-to-back FETs, the body diodes are able to stand off both positive and negative voltages. In addition, an RC snubber can be added for damping the switching oscillations in presence of a highly inductive load. SW1 Q1 VDRV + or VSSS – AC Q2 DC Load SW2 Figure 4-1. AC/DC Load b. Figure 4-2 shows an application using two parallel common source MOSFETs. This action allows the users to achieve lower RDSON. Because one MOSFET cannot block reverse current when off, the recommended load for this configuration is a DC load. SW1 + – DC Q1 VDRV Load VSSS VSSS Q2 SW2 Figure 4-2.
