Product details

Voltage supervisor for processor power-on sequencing

Its active-high, push-pull output directly drives the reset input of most MCUs without an external pull-up resistor. The 2.25 V threshold is suited for 2.5 V or 3.3 V logic rails where the system must be held in reset until the supply rises above that level. The 10 ms minimum reset timeout ensures the rail has settled before the processor begins code execution.

SOT-23-5 footprint and temperature range

Housed in a SOT-23-5 (SC-74A) package, the part occupies minimal board area and is compatible with standard surface-mount assembly processes.

Frequently asked questions

What is the reset timeout of the TPS3837J25DBVR?

The reset timeout is 10 ms minimum, providing a stable delay before the processor is released from reset after the supply rises above the 2.25 V threshold.

Can the TPS3837J25DBVR be used with 3.3 V systems?

Yes — the 2.25 V threshold is well below a nominal 3.3 V rail, so the device will hold the system in reset until the rail reaches that level and then release after the 10 ms timeout. It is designed for monitoring 2.5 V or 3.3 V supplies.
