Texas Instruments TPS7A6050QKVURQ1

Overview

TPS7A6050QKVURQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade LDO regulator delivering fixed 5-V output at up to 300 mA, with 25 µA typical quiescent current, 7–40 V input range, and integrated programmable power-on-reset (250 µs internal or capacitor-programmable delay). It serves as primary post-regulation supply for microcontrollers in head units and instrument clusters.

For engineers reviewing the TPS7A6050QKVURQ1 datasheet, TPS7A6050QKVURQ1 pinout, TPS7A6050QKVURQ1 application, or TPS7A6050QKVURQ1 equivalent, key selection criteria include its 300-mA capability under 45-V transients, ultralow I_Q in light-load automotive sleep modes, RDELAY-based reset timing flexibility, and TO-252-5 (KVU) thermally enhanced package compatibility.

Technical Context

The TPS7A6050QKVURQ1 implements a monolithic PMOS pass transistor architecture with integrated charge pump for gate drive across wide VIN, enabling stable regulation down to 7 V while supporting 45-V transient immunity. Its reset circuitry uses a precision voltage supervisor with 93% VOUT threshold detection and programmable RC delay via the RDELAY pin.

It features undervoltage lockout (VIN-UVLO = 3.16 V), thermal shutdown (T_J = 165 °C), overcurrent foldback (ICL = 350–1000 mA), and low-ESR ceramic capacitor stability - all qualified for –40°C to 125°C ambient operation per AEC-Q100 Grade 1.

FAQ

What is the maximum input voltage transient the TPS7A6050QKVURQ1 can withstand?

The TPS7A6050QKVURQ1 supports input transients up to 45 V for durations less than 480 ms, as specified in its Absolute Maximum Ratings. This capability enables robust operation during automotive load-dump events without external clamping circuitry. The device remains functional across its full 7–40 V operating range, and the TPS7A6050QKVURQ1's internal protection circuits prevent latch-up or damage during such transients.

Does the TPS7A6050QKVURQ1 require an external capacitor on the RDELAY pin?

No - the TPS7A6050QKVURQ1 operates with a fixed 250-µs power-on-reset delay when no capacitor is connected to the RDELAY pin. However, connecting an external capacitor (100 pF to 100 nF) between RDELAY and GND allows programmable delay scaling from ~300 µs to ~300 ms. The TPS7A6050QKVURQ1's internal 1-µA charging current ensures predictable RC timing without additional bias components.

What is the thermal performance of the TPS7A6050QKVURQ1 in the KVU package?

In the TO-252-5 (KVU) package, the TPS7A6050QKVURQ1 has a junction-to-board thermal resistance (R_θJB) of 6.5°C/W and a junction-to-ambient resistance (R_θJA) of 26.9°C/W under JEDEC-standard high-K board conditions. With proper PCB copper pour under the thermal pad, the TPS7A6050QKVURQ1 reliably dissipates >2 W at 125°C ambient, supporting continuous 300-mA output at elevated temperatures.

How does the TPS7A6050QKVURQ1 behave during cold-crank conditions?

During cold-crank, when battery voltage drops below 7 V, the TPS7A6050QKVURQ1 enters dropout and transitions to low-voltage tracking mode - maintaining VOUT ≈ VIN – (I_OUT × 2 Ω). This behavior, combined with its ability to operate down to 4 V for ≤130 ms, allows the TPS7A6050QKVURQ1 to sustain critical logic rails longer than conventional LDOs, reducing or eliminating the need for boost converters in automotive start-stop systems.

Is the TPS7A6050QKVURQ1 pin-compatible with other devices in the TPS7A6x-Q1 family?

Yes - the TPS7A6050QKVURQ1 shares identical pinout and package dimensions with TPS7A6033QKVURQ1 (3.3 V) in the KVU package. Both use the same 5-pin TO-252 layout with VIN, nRST, GND, RDELAY, and VOUT assignments. This enables direct voltage-option substitution on existing PCBs without layout changes, provided output capacitance and load requirements remain compatible.
