TPSI3100QDVXRQ1

Overview

The TPSI3100QDVXRQ1 is an automotive reinforced isolated switch driver designed for solid-state relay applications. It integrates a gate driver with dual isolated high-speed comparators and a bias supply, eliminating the need for secondary isolation power. The device operates on a nominal 5V rail (4.5V to 5.5V) and provides a 15.8V gate drive voltage with peak source/sink currents of 1.5A/2.5A. Key electrical parameters include a propagation delay of up to 210µs, rise/fall times of 10ns, and operation within a temperature range of -40°C to +125°C. It features 5kV RMS reinforced isolation.

Feature Summary

• Integrates gate driving and auxiliary power supply functions without requiring external isolated secondary supplies
• Provides enhanced isolation performance suitable for automotive safety-critical systems
• Includes dual-channel isolated high-speed comparators with integrated voltage reference for monitoring
• Supports direct driving of external power transistors such as MOSFETs, IGBTs, and SiC FETs

Applications

• Solid-state relays
• Battery management systems
• On-board chargers
• Hybrid, electric, and powertrain systems

Procurement Notes

Verify the specific suffix DVX indicates the SO-MOD-16 package configuration. Confirm AEC-Q100 Grade 1 qualification status for automotive deployment. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate revision levels before integration into production designs.

Selection Notes

Select this component when designing isolated switching solutions that require integrated bias generation to reduce bill-of-materials complexity. The dual comparator feature enables precise current and voltage monitoring without additional external sensing circuits. Consider the thermal performance in the SO-MOD-16 package for high-temperature environments up to 125°C. Evaluate the 5kV RMS isolation rating against system creepage and clearance requirements.

Part Context

This device belongs to the TPSI3100 family of isolated switch drivers from Texas Instruments. It serves as a modern replacement for traditional mechanical relays and optocouplers, offering higher reliability and lower power consumption. The Q1 designation confirms its compliance with automotive quality standards, making it suitable for demanding vehicular electronics applications where functional safety is paramount.

Replacement Considerations

Check for TPSI3100 variants with different package options if board space constraints differ. Verify compatibility with existing PCB footprints, as the SO-MOD-16 package has specific pinout requirements. Ensure substitute components maintain equivalent isolation voltage ratings and peak current capabilities for safe operation.
