Product details

4.55V threshold supervisor in SOT-23-5

The TPS3828-50QDBVRQ1 is a Texas Instruments simple reset/power-on reset IC designed to monitor a single 5.0V supply rail. It asserts a reset signal (active-low, open-drain output) when the monitored voltage drops below the 4.55V threshold and holds reset for a minimum of 120ms after the supply recovers.

AEC-Q100 and the 125°C ceiling

The SOT-23-5 package keeps the footprint small, but the real thermal limit is the junction temperature; at 125°C ambient the die is near its absolute maximum, so the board layout should keep the reset IC away from high-power components.

Frequently asked questions

What is the replacement for TPS3828-50QDBVRQ1?

No official replacement or successor is listed by Texas Instruments for the TPS3828-50QDBVRQ1. Any replacement would need to match the 4.55V threshold, active-low open-drain output, 120ms minimum reset timeout, SOT-23-5 footprint, and AEC-Q100 qualification. The TPS3828-50QDBVR (non-automotive grade) is a functional equivalent but lacks the AEC-Q100 rating.
