Product details

2.63V threshold — monitoring a 3.3V rail

The TPS3823-30DBVR: That threshold is set for a 3.3V rail — the reset triggers at roughly 80% of nominal, catching brownouts before the processor logic glitches. The active-low, push-pull output drives the reset pin directly without an external pull-up resistor.

Package and footprint — SOT-23-5

Housed in a SOT-23-5 package, the TPS3823-30DBVR uses the standard 5-pin supervisor footprint common across TI's TPS382x family. Surface-mount assembly is straightforward for reflow profiles typical of lead-free solders.

The base product number is TPS3823, which covers multiple threshold options in the same SOT-23-5 footprint. The -30 suffix denotes the 2.63V threshold variant.

Frequently asked questions

What is the exact reset threshold voltage of TPS3823-30DBVR?

The reset threshold voltage is 2.63V. This is the voltage at which the device asserts a reset on a monitored 3.3V rail.

Can TPS3823-30DBVR be used to monitor a 3.3V rail?

Yes. The 2.63V threshold is approximately 80% of 3.3V, which is a typical undervoltage detection point for 3.3V logic supplies. The reset triggers when the rail falls below that level.

Does TPS3823-30DBVR require an external pull-up resistor?

No. The output is push-pull, totem pole, so it drives the reset signal high or low without an external pull-up resistor. Open-drain variants of the TPS382x family would require one, but this specific order code does not.
