Product details

1.08V threshold supervisor in a SOT-23-5

It combines both Active High and Active Low reset outputs in a push-pull, totem pole configuration, giving the designer flexibility to interface with either polarity of downstream logic without an external inverter.

100 ms reset timeout — what it buys the system

The minimum 100 ms reset timeout gives the power supply and oscillator time to stabilize before the processor or FPGA is released from reset. For a typical MCU with a 10 ms startup window, the 100 ms period provides margin across temperature and supply ramp rate without requiring an external delay capacitor. The SOT-23-5 package keeps the footprint small enough for space-constrained designs like sensor nodes or distributed power modules.

Frequently asked questions

What is the reset timeout of TPS3125J12DBVT?

The reset timeout is a minimum of 100 ms, which provides a fixed delay before the reset output de-asserts after the monitored voltage rises above the threshold.

Is TPS3125J12DBVT active high or active low?

The TPS3125J12DBVT provides both Active High and Active Low reset outputs from a single push-pull stage, so it can interface directly with either polarity of reset input on the downstream processor or logic.
