The TPS3702CX18DDCR is a single-channel voltage detector from Texas Instruments, designed to assert a reset signal when the monitored supply drops below a 1.8V threshold. The active-low, open-drain output means you need an external pull-up resistor to a logic rail — typically the same rail being monitored or a separate I/O voltage — to produce a valid logic level. This part is a straightforward supervisor for a 1.8V core or I/O supply in mixed-voltage systems.
Temperature range and package for real-world placement
The TSOT-23-6 package is a thin-profile, surface-mount footprint that fits tight board stacks — the 0.95 mm nominal height helps in mezzanine or handheld designs where z-axis clearance is tight.
Active lifecycle — no obsolescence concern for new BOMs
This is a straight path for new designs and long-term supply agreements. The base product number TPS3702 covers a family of threshold options; if your target rail is not 1.8V, a sibling in the same package and pinout may fit without a PCB change.
