Key Features
- Ultra-low supply voltage operation monitors 3.0 V processor rails with an accurate factory-set threshold, eliminating external resistor dividers
- Manual reset input pin allows host processor or test equipment to assert a controlled system reset independent of supply voltage
- 5-pin SOT-23 package occupies minimal PCB area and suits space-constrained portable and wearable designs
Applications
TPS3125L30DBVR supervises microcontroller and DSP supply rails in battery-powered consumer electronics, wearable devices, and industrial handheld instruments where reliable power-on reset is critical. It asserts a reset pulse during power-up and brownout conditions, preventing corrupted code execution when supply voltage drops below the 3.0 V threshold. The manual reset input also supports remote reset triggering from a supervisory controller or front-panel pushbutton.

Frequently Asked Questions
At what supply voltage threshold does TPS3125L30DBVR assert its reset output?
TPS3125L30DBVR asserts its active-low reset output whenever the monitored supply drops below approximately 3.0 V, with a factory-trimmed threshold accuracy of ±2%. The reset remains asserted until supply voltage rises above the threshold and a fixed timeout delay of 200 ms elapses, ensuring the processor has a stable rail before releasing reset.
How does the manual reset input on TPS3125L30DBVR work, and what logic level activates it?
The MR pin on TPS3125L30DBVR is an active-low input that immediately asserts the reset output when pulled below 0.8 V. This allows an external pushbutton, open-drain signal, or microcontroller GPIO to force a system reset independently of supply voltage conditions, which is useful during firmware development and field servicing of embedded boards.
What is the quiescent supply current of TPS3125L30DBVR, and how does that affect battery life in portable designs?
TPS3125L30DBVR draws typically less than 15 µA quiescent supply current at 3.0 V, making it well suited for always-on supervisor roles in battery-operated products. In a system with a 1000 mAh lithium-ion cell, the supervisor alone would consume under 0.1% of total capacity, contributing negligibly to standby discharge over thousands of hours of shelf or idle time.
