TPSI31xx-Q1 evaluation module (EVM) helps designers evaluate the operation and performance of the TPSI31xx-Q1 device family. The board features the TPSI3100-Q1, an isolated switch driver with integrated 15.8-V gate supply and fault/alarm indicators. The TPSI3100-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 15.8-V power supply, which allows for a wide selection of power switches such as MOSFETs, SiC MOSFETs, and IGBTs. The EVM features a current sense amplifier (INA181) and is intended for overcurrent protection with two-level detection (5-A alarm, 10-A fault). The EVM also includes an N-Channel 750-V 44-A silicon carbide (SiC) MOSFET in a TO-263-7L package. The board contains multiple test points to monitor TPSI3100-Q1 functionality. In addition, the EVM contains an adjustable 5-V LDO to support battery powering.
