Product details

1.14V threshold supervisor — SOT-23-5, active-low open-drain

With a 100ms minimum reset timeout, it holds the target device in reset long enough for the supply to stabilise after power-up.

Industrial temp, SOT-23-5 footprint

The SOT-23-5 (SC-74A) package is a 5-pin surface-mount footprint common for small-signal devices; the 0.95 mm pin pitch is hand-solderable and routes easily on two-layer boards.

For BOM lines that still call out this exact order code, the only channel is independent distribution — surplus inventory, new-old-stock, or broker-sourced material.

Frequently asked questions

What is the output type of TPS3128E12DBVRG4?

It has an active-low open-drain output. You must connect an external pull-up resistor to the monitored rail or the processor's I/O voltage for the reset signal to reach a valid logic-high level.
