Product details

The TPS3808G30DRVT is a single-channel voltage supervisor from Texas Instruments, listed as a Simple Reset/Power-On Reset type with an Active Low, open-drain output. Its 2.79V threshold is set for monitoring a 3.0V or 3.3V rail — when that rail drops below 2.79V, the reset output pulls low and holds until the supply recovers and the timeout expires. The reset timeout is adjustable via an external capacitor on the CT pin, which lets you match the delay to the downstream processor's power-good requirement without adding a separate timer IC.

ROHS3 compliant.

Frequently asked questions

How do I adjust the reset timeout on TPS3808G30DRVT?

The reset timeout is adjustable/selectable via an external capacitor on the CT pin. The datasheet provides the capacitance-to-timeout curve.

Is TPS3808G30DRVT compatible with 1.8V systems?

No — the 2.79V threshold is designed for 3.0V/3.3V rails. For a 1.8V rail, you would need a supervisor with a lower threshold, such as the TLV803EA29VDBZR which has a 2.93V threshold and is also active-low open-drain.

When sourcing TPS3808G30DRVT, what is the closest functional second-source?

The TLV803ED29DBZR has a 33 ms minimum timeout. Neither is a drop-in replacement — verify the threshold and timeout in your circuit.
