Product details

Voltage supervisor for a single 2.25V rail

The open-drain output stays low for a minimum of 20ms after the supply returns above threshold, giving the downstream processor time to stabilize.

The 2.25V threshold is the trip point at which the reset asserts; if your rail is a 2.5V or 3.3V supply, this part triggers before the processor's brown-out level, ensuring a clean reset. The 20ms minimum reset timeout is long enough to cover most power-supply ramp-up transients and oscillator startup delays in a typical MCU or DSP system.

Frequently asked questions

What is the reset timeout of TPS3813J25DBVRG4?

The reset timeout is a minimum of 20ms. The open-drain output holds low for at least that duration after the supply voltage rises above the 2.25V threshold.

What is the closest pin-compatible alternative to TPS3813J25DBVRG4 in this component family?

Within the TPS3813 family, other threshold-voltage variants (e.g., TPS3813J33 for 3.3V rails) share the same SOT-23-6 pinout and active-low open-drain output. For a direct 2.25V threshold replacement, the TPS3813J25DBVRG4 is the only option at that specific trip point.
