Key Features
- AEC-Q100 automotive-qualified USB charging port controller for in-vehicle USB power management
- Adjustable overcurrent threshold enables flexible current limiting from 4.5 V to 5.5 V input range
- Single-channel 16-pin QFN integrates power switch and USB charging port controller in a compact footprint
Applications
The TPS2543QRTERQ1 is designed for automotive USB charging port management in center consoles, door modules, and infotainment systems that require AEC-Q100 Grade reliability. Its adjustable current threshold and integrated power switch enable automatic USB device detection and controlled charging current delivery without external sense resistors. The 16-pin QFN package and 4.5 V to 5.5 V input range suit it for 5 V USB power bus applications where space is limited and automotive temperature range is mandatory.

Frequently Asked Questions
What input voltage range does the TPS2543QRTERQ1 support, and how does it fit into a 5 V automotive USB charging rail?
The TPS2543QRTERQ1 operates from a 4.5 V to 5.5 V input voltage range, which directly covers the standard 5 V USB VBUS rail with typical ±10% tolerance. This makes it a direct-fit power switch for automotive USB charging ports without requiring an upstream regulator, provided the vehicle's USB hub output stays within the 4.5 V to 5.5 V window.
How does the adjustable overcurrent threshold on TPS2543QRTERQ1 simplify charging port current management?
The adjustable threshold pin allows designers to set the current limit by selecting an external resistor value, enabling current limiting from below 1 A up to the device's rated maximum without changing ICs. This single resistor adjustment lets the same TPS2543QRTERQ1 BOM position be reused across multiple USB port configurations—such as 500 mA standard ports and 2.1 A fast-charge ports—in a 4.5 V to 5.5 V automotive system.
What AEC-Q100 Grade does TPS2543QRTERQ1 carry, and what temperature range does that imply for automotive placement?
The TPS2543QRTERQ1 carries AEC-Q100 Grade 1 qualification, which requires operation and reliability verification across -40°C to +125°C junction temperature. This grade covers demanding automotive placements such as near heat sources in engine-adjacent modules or under-dash environments, ensuring the 16-pin QFN device maintains its USB port switching and current-limit functions throughout the vehicle's thermal lifetime.
