Why a 1V threshold voltage detector matters for your rail monitoring
The TPS3702CX10QDDCRQ1 is a single-channel voltage detector with a fixed 1V threshold — that specific trip point is what you need when the core supply of a 1.0V logic rail must be held in reset until it's stable. The active-low, open-drain output means it pulls the reset line low when the monitored voltage drops below 1V; you supply the pull-up resistor to your own logic rail, which keeps the output voltage independent of the monitored supply. This is a single-voltage supervisor — it watches exactly one rail. If your board needs to sequence multiple supplies, you stack one TPS3702 per rail.
What the AEC-Q100 grade and package mean for your BOM
The part carries Automotive, AEC-Q100 qualification — that's the production-part qualification (PPAP) traceability that automotive Tier-1 and OEM buyers require. The TSOT-23-6 package is a 6-lead thin SOT-23 with 0.95 mm pitch; it's a common footprint shared with many TI supervisors, so a layout change to a different threshold or reset timeout is often a drop-in swap. Lifecycle status is Active, and it's ROHS3 Compliant — no PCN risk from a looming phase-out.
