Description
The STM6710 is a precision voltage-monitoring supervisor with the capability to monitor
triple/quad voltages and combines 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 as shown in
page 20
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 SOT-23 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

This device will function as a triple monitoring voltage supervisor (STM6700) when V2IN is
used as V
The output is open drain with a weak internal pull-up to the monitored V2IN supply (or V
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
and STM6710 the condition is to have V
