What are the key features of TPS7A6050Q1?
- Wide input voltage range up to 60 V continuous for direct connection to 12 V, 24 V, or 48 V automotive bus
- 50 mA output current in a DPAK (TO-252) package with exposed pad for thermal management
- AEC-Q100 Grade 1 automotive qualification for reliable operation in vehicle environments
- Low quiescent current suitable for always-on battery-connected standby supply rails
- Wide operating temperature range of -40°C to +125°C for harsh automotive and industrial use
What is TPS7A6050Q1 used for?
The TPS7A6050Q1 is designed for automotive body control modules, gateway ECUs, and telematics units where a low-current always-on 3.3 V or 5 V rail is derived directly from the vehicle battery at up to 60 V. Its AEC-Q100 qualification and -40°C to +125°C temperature range make it suitable for under-hood sensor power supplies and industrial fieldbus node power conditioning. The DPAK package with exposed pad allows heat dissipation directly into PCB copper, supporting reliable operation at elevated ambient temperatures.

Frequently Asked Questions
Can the TPS7A6050Q1 be connected directly to a 48 V mild-hybrid automotive battery rail?
Yes. The TPS7A6050Q1 supports input voltages up to 60 V continuously, which comfortably accommodates the 48 V nominal bus voltage used in mild-hybrid vehicles, including load-dump transients. This eliminates the need for a pre-regulator or protection circuitry in most 48 V automotive standby supply designs.
What automotive qualification level does the TPS7A6050Q1 meet, and what does that mean for temperature range?
The TPS7A6050Q1 carries AEC-Q100 Grade 1 automotive qualification, which covers a junction temperature range of -40°C to +125°C. Grade 1 is suitable for under-hood and other harsh automotive environments with elevated ambient temperatures, giving designers confidence in long-term reliability for production vehicle programs.
How much output current does the TPS7A6050Q1 supply, and is that enough for powering microcontroller keep-alive circuits?
The TPS7A6050Q1 provides up to 50 mA of regulated output current. This is typically more than sufficient for always-on microcontroller keep-alive functions, RTC oscillators, and CAN bus wake-up receivers, which commonly require only 1 mA to 20 mA during low-power standby, leaving margin for peripheral loads.
What thermal considerations apply when using the TPS7A6050Q1 in a DPAK package at high input voltages?
In the DPAK (TO-252) package, power dissipation equals (VIN - VOUT) × IOUT. At 60 V input, 5 V output, and 50 mA load, this reaches 2.75 W. PCB copper pours under the exposed pad, the DPAK's thermal path to the board, are essential to keep junction temperature below 125°C. The thermal resistance junction-to-board determines the required copper area.
