Product details

1.4 V threshold supervisor for low-voltage rails

The reset outputs are push-pull, totem pole, configurable as active high or active low, giving the designer flexibility to interface with either reset polarity on the downstream processor or FPGA. The 100 ms minimum reset timeout holds the system in reset long enough for the supply to stabilise after a brown-out or power-up event, avoiding premature processor start-up.

Industrial temperature range and SOT-23-5 footprint

This removes the last-time-buy risk for new designs and production runs.

Frequently asked questions

Can TPS3125G15DBVR be used as a drop-in replacement for TPS3125G12DBVR?

The TPS3125G12DBVR has a 1.2 V threshold, while this part triggers at 1.4 V. They are pin-compatible in the same SOT-23-5 footprint, but the different threshold means the reset will assert at a higher voltage — verify that the downstream processor's minimum operating voltage is above 1.4 V before substituting.

What is the difference between TPS3125G15DBVR and TPS3125G18DBVR?

The TPS3125G18DBVR has a 1.8 V threshold; this part triggers at 1.4 V. Both are in the same SOT-23-5 package and share the same reset timeout and output structure. The choice depends on the supply rail you are monitoring.

Is TPS3125G15DBVR RoHS compliant?

Yes, the TPS3125G15DBVR is RoHS compliant, which is standard for Texas Instruments surface-mount supervisors in this series.
