Description

The STM6710 is a precision voltage monitoring supervisor with the capability to monitor

triple/quad voltages and combine competitive reset threshold accuracy with low power

consumption.

Factory-trimmed reset threshold options for monitoring 5.0 V, 3.3 V, 2.5 V and 1.8 V supplies

with –5% and –10% tolerances are available.

If a monitored supply voltage input falls below the minimum voltage threshold, a single

active low output is asserted, triggering a system reset.

This device can be configured to support an external manual reset input using minimal

external components.

Monitoring up to four different voltages in a small 6-lead SOT23 package, the STM6710

devices can help to lower system cost, reduce board space requirements, and increase the

reliability of multi-voltage systems.

respective minimum voltage thresholds. The reset signal remains asserted until all of these

voltages return to proper operating levels and stabilize.

STM6710 includes internally fixed monitoring voltages for 5.0 V, 3.3 V, 3.0 V, 2.5 V and 1.8

V supplies with –5% and –10% tolerances.

This device functions as a triple monitoring voltage supervisor (STM6700) when V2IN is

in the case of STM6710Q) of typically 10 µA. Once all voltages rise above the selected

threshold level, the STM6710 reset signal remains low for the reset timeout period of

200 ms (typical). The STM6700 acts as a voltage detector with a propagation delay of 5 µs

after all monitored voltages exceed their thresholds.

The STM6710 output remains valid as long as V1IN or V2IN exceeds 1 V. For the STM6700
