Product details

Two-rail watchdog in a 1.45×1 mm SON

The TPS3779DDRYT monitors two independent voltage rails with adjustable/selectable thresholds, making it a fit for multi-supply systems where a single supervisor IC must cover core and I/O or analog and digital domains. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, saving one component per channel.

125°C junction rating and small footprint

The 6-SON package measures 1.45×1 mm — the 0.5 mm pitch requires a fine-pitch soldering profile but frees board area for other passives.

The part is ROHS3 compliant. Sourced to order against BOM quantities — confirm the exact threshold configuration and the mating half of the supply rail before committing.

Frequently asked questions

What is the closest functional second-source to TPS3779DDRYT?

The TLV803EA29VDBZR is a simple reset/power-on reset with active-low, open-drain output, but it monitors a single rail with a fixed 2.93 V threshold and a 130 ms minimum reset timeout. The TPS3779DDRYT offers two adjustable channels and push-pull output, so the TLV803 is not a direct pin-for-pin replacement — it covers a different supervision architecture.
