Overview
The TPSI3050SQDWZRQ1 is an automotive reinforced isolated switch driver from Texas Instruments, housed in an 8-SO-MOD package. It operates within a supply voltage range of 3 V to 5.5 V and supports junction temperatures from -40°C to +125°C. The device features a single channel with a maximum propagation delay of 4.5 µs, rise time of 6 ns, and fall time of 5 ns. It delivers peak output currents of 1.5 A or 3 A and includes an integrated 10.2 V gate supply. Power dissipation is rated at 350 mW.
Feature Summary
- Automotive reinforced isolation for high-voltage safety
- Integrated 10-V gate supply eliminates external bias requirements
- Single-channel galvanically isolated architecture
Applications
- Electric vehicle battery management systems
- High-voltage solid-state relay implementations
- Automotive power switching circuits
Procurement Notes
Verify the specific suffix 'SQ' against the manufacturer's official datasheet to confirm it denotes the correct automotive grade and reinforcement level. Ensure the SO-MOD-8 package matches your PCB footprint requirements. Confirm RoHS compliance status directly with the supplier documentation before finalizing procurement orders.
Selection Notes
Select this component when automotive reinforced isolation is mandatory for safety certification. The integrated gate supply simplifies design by removing external bias components. Verify that the 3000 Vrms insulation rating meets the system's isolation requirements. Consider the 350 mW power dissipation limit for thermal management planning in enclosed environments.
Part Context
This part belongs to the TPSI3050 family of isolated switch drivers designed for electric vehicle applications. It integrates power and signal transfer in a single chip to reduce cost and size while maintaining robust isolation. The series addresses the increasing voltage demands of modern EV batteries by providing safe high-voltage handling capabilities.
Replacement Considerations
The TPSI3050QDWZRQ1 is a related variant within the same family. Verify if the 'SQ' suffix indicates a specific qualification or reinforcement difference compared to standard versions. Consult the official substitution guide to ensure electrical and isolation parameters remain compatible.
