Voltage supervisor for 3.3V rails — what the 2.93V threshold means
The 2.93V threshold is set for a nominal 3.3V rail with enough margin to catch brownout conditions before the downstream logic enters an undefined state. The open-drain output lets you wire-OR the reset signal with other supervisors or pull it up to a different voltage domain.
120 ms reset timeout — why it matters for processor boot
If the timeout were shorter, a fast-rising supply could release reset before the clock is valid, leading to erratic boot behaviour. This part is a drop-in fit for any 3.3V MCU or FPGA that expects an active-low reset with a 100–200 ms delay.
Industrial temperature range and SOT-23-5 package
The base product number TPS3828 covers multiple voltage threshold options (2.63V, 2.93V, 3.08V, 4.38V) in the same pinout, so a BOM change to a different threshold does not require a layout revision.
