Product details

Supply current and voltage range — fit for battery and multi-rail systems

Drawing 10 µA typical supply current, the TPS3430WDRCR adds negligible load to a battery or energy-harvesting rail — the watchdog's own draw is well below the self-discharge rate of a coin cell, so a system that sleeps for months and wakes on a fault still sees minimal drain.

Package and board-fit — 10-VSON with exposed pad

Housed in a 10-VFDFN Exposed Pad package (3x3 mm, supplier device package 10-VSON), the TPS3430WDRCR occupies a small PCB footprint. The exposed thermal pad should be soldered to a ground-plane copper pour to keep junction temperature within the -40°C to 125°C range under continuous operation.

Compliance documentation

ROHS3 compliant.

Frequently asked questions

What is TPS3430WDRCR's listed type?

The TPS3430WDRCR is a Watchdog Circuit — a supervisory IC that monitors system activity and asserts a reset or interrupt if the host fails to strobe the watchdog input within a programmed timeout window.
