Description
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.
Features
- Replaces large, high power pre-charge resistors using a switched converter architecture
- Improved thermal performance compared to passive pre-charge solutions
- Hysteretic current control for linear charging of downstream capacitance
- Drives external power transistors such as Si, SiC MOSFET, or IGBT-Integrated isolated secondary supply for gate bias-17V gate drive, 1.5A and 2.5A peak source and sink current-AEC Q-100 qualified for automotive applications
- Temperature grade 1: –40°C to +125°C, TA-Functional Safety-Capable
- Documentation available to aid functional safety system design-Safety-related certifications
- Planned: 7070VPK reinforced isolation per DIN EN IEC 60747-17 (VDE 0884-17)
- Planned: 5kVRMS isolation for 1 minute per UL 1577
Typical applications
- Alternative Energy
- Energy Storage and Battery Management
- Automotive and Transportation
