Product overview

Description

The STM6905 supervisor is a low voltage/low supply current processor supervisor, designed to monitor up to five system power supply voltages. This device is targeted at applications such as set-top boxes (STBs), portable, battery-powered systems, networking and communication systems. The device supports a push-button type manual reset input (MR). Two of the five supply monitors (VCCand V2IN) have fixed (customer-selectable, factory-trimmed) thresholds (VRST1and VRST2). The other three voltage monitor inputs (V3IN, V4IN and V5IN) are monitored using externally adjustable threshold (600 mV internal reference) to meet specific level requirements.
If any of the five monitored voltages drops below its factory-trimmed or adjustable thresholds, or if the MRis asserted to logic low, the reset output RSTis asserted (driven low). Once asserted, RSTis maintained low for a minimum delay period (tREC) after ALL monitored supplies rise above their respective thresholds and MRreturns to high. The reset output logic state is valid for VCCgreater than 0.8 V.
The STM6905 is available in a standard 8-lead MSOP (TSSOP) package.
  • All features

    • Quintuple voltage monitoring
    • Accurate ±1.8 % across temperature voltage threshold (±1 % at 25 °C)
    • Primary supply (VCC) monitor. Fixed (factory -programmed) reset thresholds: 3.078 V to 2.866 V
    • Second fixed (V2IN) monitor. Fixed (factory-programmed) reset thresholds: 2.333 V to 1.050 V
    • Three additional adjustable supply monitor inputs (externally adjustable)
    • 600 mV internal reference
    • RSToutput (open drain)
    • Output guaranteed for VCC ≥ 0.8 V
    • Reset delay time (TREC) on power-up: 210 ms (typ)
    • Manual reset input (MR)
    • Low supply current of 12 μA (typ)
    • Power supply voltage 0.8 V to 5.5 V
    • RoHS compliant (green package)
    • 8-pin MSOP/TSSOP
    • Operating temperature: –40 °C to 85 °C (industrial grade)
