The open-drain output means the reset pin is a pull-down only; you supply the pull-up resistor to your logic rail. This lets the reset signal swing to whatever voltage the downstream device needs — 1.8V, 3.3V, or 5V — without a level shifter. ## 270 ns propagation delay — timing margin for fast-core processors With a typical propagation delay of 270 ns, the TL7702BID responds to a supply dip within a quarter-microsecond. For a 200 MHz ARM core running at 3.3V, that delay represents about 54 clock cycles — enough headroom to latch the reset before the core logic enters an undefined state, but short enough that a brief brown-out on a heavily switched regulator won't cause a false trip. The single-voltage monitoring means this part watches one rail. If your system has multiple supplies (core, I/O, analog), you'll need one TL7702BID per rail or a multi-channel supervisor. The 8-SOIC package takes about 30 mm² of board area per channel.","metaTitle":"Texas Instruments TL7702BID Simple Reset IC, 2.53V Threshold","metaDescription":"TL7702BID supervisor IC from TI: active high/low reset, open-drain output, 2.53V threshold, 270ns propagation delay.

For a 3.3V rail, this gives about 770 mV of margin below nominal — enough to catch a brown-out before the logic supply drops below the minimum operating voltage of most 3.3V CMOS devices (typically 2.7V to 3.0V)."},{"question":"What compliance documentation does Texas Instruments provide for TL7702BID?","answer":"The TL7702BID is RoHS3 compliant.
