Key Features
- AEC-Q100 Grade 1 automotive-qualified power management IC supporting Li-Ion battery charging at up to 500 mA for automotive and industrial applications
- Integrated 3.0 V to 4.4 V input range with thermal regulation and overcharge protection ensures safe battery management across -40°C to 125°C operating range
- Compact 16-pin QFN package integrates charger and system power path management, reducing external component count in automotive infotainment and telematics designs
Applications
The TPS6503300IQRGETQ1 is designed for automotive infotainment systems, telematics control units, and e-call backup power modules requiring AEC-Q100 Grade 1 compliant Li-Ion battery charging and power management. Its integrated power path management allows the system to operate from an automotive 12 V supply through a pre-regulator while simultaneously charging a backup battery at up to 500 mA. The device also suits industrial portable instruments and medical devices requiring automotive-grade reliability across the full -40°C to 125°C temperature range.

Frequently Asked Questions
What automotive qualification grade does the TPS6503300IQRGETQ1 hold and what does this mean for temperature range?
The TPS6503300IQRGETQ1 is qualified to AEC-Q100 Grade 1, meaning it is tested and guaranteed to operate reliably over a junction temperature range of -40°C to 125°C. This qualification is mandatory for components used in automotive under-hood and harsh-environment electronic control units subject to wide temperature cycling and vibration stress.
What is the maximum charge current of the TPS6503300IQRGETQ1 and how is it set?
The TPS6503300IQRGETQ1 supports a maximum Li-Ion battery charge current of 500 mA, programmable via an external resistor connected to the ISET pin. Lower charge currents can be selected for smaller battery capacities or thermally constrained environments, with the IC automatically reducing current via internal thermal regulation when junction temperature exceeds safe limits.
Which package does TPS6503300IQRGETQ1 use and what are the thermal considerations for 500 mA charging?
The TPS6503300IQRGETQ1 is housed in a 16-pin QFN package with an exposed thermal pad measuring approximately 3 mm × 3 mm. At 500 mA charge current, the power dissipation can reach 250 mW to 500 mW depending on input-to-battery voltage differential, requiring the thermal pad to be soldered to a PCB copper pour with at least 4 thermal vias to maintain junction temperature below 125°C.
How does TPS6503300IQRGETQ1 differ from a non-automotive TPS65033 variant for an automotive telematics design?
The TPS6503300IQRGETQ1 carries AEC-Q100 Grade 1 automotive qualification and is manufactured with automotive PPAP-compliant processes, whereas non-automotive TPS65033 variants are qualified only to commercial or industrial temperature grades up to 85°C. For automotive telematics designs subject to IATF 16949 supply chain audits, the Q1 suffix guarantees device traceability and ensures compliance with OEM quality requirements that non-Q1 parts cannot satisfy.
