It holds the reset output for a minimum of 100 ms after the supply recovers, giving the downstream processor time to stabilise its internal power-on sequence. The push-pull output stage drives both active-high and active-low reset signals from the same device — no external pull-up resistor or inverter needed. This simplifies the board layout and saves a component on the BOM.
The reset timeout is a minimum of 100 ms. This means the reset output stays asserted for at least 100 ms after the monitored supply rises above the 1.4 V threshold.
The TPS3124G15DBVR provides both active-high and active-low reset outputs from the same push-pull stage. No external inverter is needed to select polarity.
It comes in a SOT-23-5 (SC-74A) surface-mount package, also referred to as the supplier device package SOT-23-5.
The TPS3124G12DBVR has a 1.2 V threshold; the TPS3124G15DBVR has a 1.4 V threshold. They are pin-compatible but monitor different supply voltages — confirm the rail voltage before substituting.
