Description

The TPSI31Px-Q1 evaluation module (EVM) helps designers evaluate the operation and performance of the TPSI31Px-Q1 device family. The board features the TPSI31P1-Q1, an isolated switch driver with integrated 17V gate supply and comparators to monitor charging current and hysteretically drive the gate, completely on the secondary side with no additional logic needed. This functionality allows the TPSI31P1 to charge a DC-link capacitor in any application including electric vehicles (EV) or hybrid electric vehicles (HEV) as a high-side active precharge solution. For additional switching power, the TPSI3052, is included in the EVM design, but not required. The TPSI3052 is an isolated switch driver with integrated 17V gate supply which can be used as a supplementary isolated power supply. The EVM features a buck topology using a HV inductor. The EVM also includes an N-Channel silicon carbide (SiC) MOSFET with a small 14nC gate charge which helps us minimize overall switching power needed. The board contains multiple test points to monitor TPSI31P1-Q1 functionality. In addition, the EVM contains an adjustable 5V LDO for flexible power input.
