Product details

Dual-rail supervisor for mixed-voltage systems

The TPS3780CDRYT is a multi-voltage supervisor designed to monitor two independent supply rails, with an active-low, open-drain reset output. It suits applications where a core voltage and an I/O voltage must both stay within tolerance before the system is allowed to run — common in SoCs, FPGAs, and dual-supply MCUs. The adjustable/selectable threshold gives the designer flexibility to set the trip point per rail using external resistors, rather than being locked into a fixed voltage.

Frequently asked questions

Is TPS3780CDRYT a direct replacement for TPS3780CDR?

The base product number is TPS3780. The suffix 'CDRYT' indicates the specific package and reel configuration — 6-SON (1.45x1.00 mm) on Tape & Reel. TPS3780CDR is a different package variant; confirm the footprint matches your PCB land pattern before substituting.

What is the closest functional second-source to TPS3780CDRYT?

The TLV803EA29VDBZR and TLV803ED29DBZR are simple reset ICs with active-low, open-drain output, but they monitor a single voltage and have a fixed reset timeout (130 ms and 33 ms respectively). The TPS3780CDRYT monitors two channels with adjustable thresholds — not a pin-compatible replacement, but a functional alternative if only one rail needs supervision.
