Product details

Dual-rail supervisor with 1.68 V and 2.93 V thresholds

The Texas Instruments TPS3305-18DGNRG4 is a multi-voltage supervisor that monitors two supply rails — one at 1.68 V and the other at 2.93 V — and asserts a reset when either drops below its threshold. The reset outputs are available in both active-high and active-low push-pull configurations, giving the designer flexibility to interface with different processor reset schemes without external inverters.

140 ms reset timeout for sequenced power-up

This avoids spurious boot failures on systems where the core rail stabilises before the I/O rail.

The 8-HVSSOP package with exposed pad helps conduct heat to the PCB ground plane, keeping the die temperature within the operating range even in enclosed enclosures.

Frequently asked questions

Does TPS3305-18DGNRG4 have push-pull output?

Yes, the reset outputs are push-pull, totem-pole type. Both active-high and active-low outputs are available on the same device, so you can drive either polarity without an external inverter.

Is TPS3305-18DGNRG4 obsolete?

There is no indication of discontinuation or last-time-buy.

What is the reset timeout for TPS3305-18DGNRG4?

The reset timeout is a minimum of 140 ms. This is the duration the reset output remains asserted after all monitored voltages rise above their thresholds.
