That 1.71V threshold is the key number: it sits just above the minimum operating voltage of most 1.8V-logic devices, so the reset asserts before the downstream logic enters an undefined state on brownout or power-up. ## Open-drain output — wired-OR and level-shifting The open-drain output lets you pull the reset line up to any voltage within the absolute maximum of the drain pin — common in mixed-voltage boards where the supervisor runs on 1.8V but the reset input of a 3.3V MCU needs a pull-up to its own rail. It also allows multiple open-drain reset outputs to be wire-OR'ed to a single processor reset input. ## Package and footprint — SOT-23-5 Housed in a 5-pin SOT-23 (SC-74A), the TPS3838E18DBVR takes minimal board area — about 3.0 mm x 3.0 mm including the pin fan-out. The 0.95 mm pin pitch is a standard small-signal footprint; no thermal pad is needed because the quiescent current is low enough that self-heating is negligible even at 85°C ambient.","metaTitle":"TI TPS3838E18DBVR Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3838E18DBVR: active-low open-drain reset IC, 1.71V threshold, 10ms min timeout, SOT-23-5.
