Product details

Automotive-grade reset for 3.3 V rails

170 ms reset timeout — what it buys the system

The 170 ms minimum reset timeout gives the downstream MCU, SoC, or FPGA a guaranteed window for its core supply to stabilise before the reset is released. In a multi-rail power-up sequence this prevents the processor from starting execution before the I/O and memory rails are within tolerance.

Wettable flank package for AOI inspection

The 8-VSON (3x3 mm) package features wettable flanks, meaning the side terminations are designed to wick solder during reflow. This creates a visible solder fillet that automated optical inspection (AOI) systems can verify, a requirement in many automotive and high-reliability assembly lines where hidden solder joints under the package are not acceptable.

The AEC-Q100 qualification also covers the extended reliability testing — pre-conditioning, high-temperature operating life, and temperature cycling — that the automotive tier-1 supply chain requires.

Frequently asked questions

Does TPS3851G33SQDRBRQ1 have a wettable flank package?

Yes, the 8-VSON (3x3 mm) package is specified with wettable flanks, enabling automated optical inspection (AOI) of the solder joints after reflow.

What is the reset timeout for TPS3851G33SQDRBRQ1?

The reset timeout is a minimum of 170 ms, measured from the moment the monitored 3.3 V rail rises above the threshold until the reset output is released.

Is TPS3851G33SQDRBRQ1 automotive qualified?

Yes, it is qualified to AEC-Q100, the automotive electronics council stress-test standard, and is part of the Automotive series.
