Frequently Asked Questions
What is the input voltage range and output current capability of the TPS2051BQDRQ1?
The TPS2051BQDRQ1 operates with an input voltage range of 2.7V to 5.5V, making it compatible with both 3.3V and 5V power rails. Each of its two independent channels can deliver up to 2A of continuous output current, suitable for driving moderate loads in automotive and industrial applications.
Is the TPS2051BQDRQ1 qualified for automotive applications?
Yes, the TPS2051BQDRQ1 is AEC-Q100 qualified (Grade 1) for automotive use, as indicated by the 'Q1' suffix in its part number. It meets the stringent reliability and temperature requirements demanded by automotive system designers for use in infotainment, body control, and ADAS modules.
What protection features does the TPS2051BQDRQ1 include?
The TPS2051BQDRQ1 integrates undervoltage lockout (UVLO), which disables the output channels when the input voltage falls below a safe threshold. This prevents downstream components from operating under inadequate supply conditions, improving system reliability in automotive and industrial environments.
What package does the TPS2051BQDRQ1 come in, and how can I order it?
The TPS2051BQDRQ1 is available in an 8-pin Small Outline IC (SOIC-8 / R-PDSO-G8) package, which is easy to hand-solder and widely supported by PCB footprint libraries. It is in stock and available for worldwide shipping starting from approximately $0.52 per unit.
