Product overview
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.
Low VCCdetection circuitry protects the user's system from low voltage conditions, resetting the system when VCCor any of the other monitored power supply voltages fall below their 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 used as VCC.
The output is open drain with a weak internal pull-up to the monitored V2IN supply (or VCCin 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 VCCabove 2 V.
