Product details

Voltage supervisor for 3.3V rails — threshold and timeout

The reset output is open-drain, so it can be pulled up to any voltage up to the absolute maximum of the output transistor, making it compatible with 1.8V, 2.5V, or 3.3V logic interfaces without a level shifter.

Adjustable reset timeout — matching the downstream POR

The reset timeout period is adjustable or selectable via an external capacitor on the CT pin, which lets the designer set the hold time from microseconds to seconds to match the processor's power-on reset requirement and the supply ramp characteristics. This flexibility avoids the need for a separate timer IC or a supervisor with a fixed, non-negotiable timeout that might be too short for a slow-ramping supply or too long for a fast-starting system.

Frequently asked questions

Can TPS3808G33DRVT be used for 3.3V monitoring?

Yes. The voltage threshold is 3.07V, which is the typical undervoltage detect point for a 3.3V supply rail. When the monitored voltage falls below 3.07V, the active-low reset output asserts.

What is the equivalent of TPS3808G33DRVT?

The TPS3808G33DRVR is the same silicon in a different reel packaging option. The base product number TPS3808 covers the whole family; the suffix DRVT vs DRVR differs only in tape-and-reel quantity and reel diameter, not in electrical or thermal performance.

How to adjust reset timeout on TPS3808G33DRVT?

The reset timeout is adjustable via an external capacitor connected between the CT pin and ground. The timeout period is proportional to the capacitance value; the datasheet provides the formula and typical values for common timeout durations.
