4.55V threshold supervisor for 5V rails
The push-pull, totem-pole output drives directly into the reset input of a microcontroller or DSP without an external pull-up resistor.
120 ms timeout — why it matters at power-up
For a 5V rail feeding a Cortex-M or similar MCU, this window covers the typical 10–50 ms bulk-capacitor charging period.
SOT-23-5 footprint — common supervisor pinout
The part is supplied in an SC-74A / SOT-753 package, commonly referred to as SOT-23-5. The 5-pin surface-mount footprint is shared across many TI supervisor ICs (TPS382x, TPS383x families), so a pin-compatible swap for a different threshold or timeout variant does not require a board respin.
