Product details

2.93V threshold, active-high — the reset IC for automotive 3.3V rails

The TPS3837K33QDBVRQ1: The active-high push-pull output means the RESET pin goes high when the monitored voltage drops below 2.93V — a polarity that is less common than active-low, so the downstream logic input must match.

Reset timeout and package — what the 10ms minimum buys you

This is a fixed timeout — no external capacitor needed. Housed in a 5-pin SOT-23-5 (SC-74A) package, the footprint is a standard 0.95 mm pitch with a 2.9 mm × 1.6 mm body — a direct fit for space-constrained automotive PCBs where a supervisor must sit close to the processor supply pin.

Frequently asked questions

What is the replacement for TPS3837K33QDBVRQ1?

No official replacement is listed. The base product number is TPS3837; an engineer evaluating a substitute should look for a pin-compatible simple reset IC with the same 2.93V threshold, active-high push-pull output, and AEC-Q100 qualification in the SOT-23-5 package.
