Overview

The TPSI31Px-Q1 evaluation module (EVM) helps designers evaluate the operation and performance of TPSI31P1-Q1 in an electric vehicle (EV) or hybrid electric vehicle (HEV) high-side active precharge application for charging a DC-link capacitor.

  • TPSI31PXQ1EVM: 800VDC with 10AAVG
  • TPSI31PXQ1EVM-400: 400VDC with 4.5AAVG

Features
  • TPSI31PXQ1EVM for charging 2mF capacitor to 800V in 160 ms
  • TPSI31PXQ1EVM-400 for charging 2mF capacitor to 400V in 180 ms
  • Integrated hysteretic charging current control, no additional logic needed
  • No isolated secondary supply required
  • 5-kVRMS reinforced isolationDual isolated high-speed comparators with integrated voltage reference ±1.5%
