Product overview

Description

The STM6717/18/19/20 and STM6777/78/79/80 supervisors are a family of low-voltage/low-supply current processor (micro or DSP) supervisors, designed to monitor two (or three) system power supply voltages. They are targeted at applications such as set-top boxes (STBs), portable, battery-powered systems, networking, and communication systems. All device options have a push-button-type manual reset input (MR). The STM6777/78/79/80 also includes an option which enables the user to delay the start of the manual reset process from 6 μs (MRC pin left open) or more with external capacitor. The delay is implemented by connecting the appropriately sized capacitor between the MRC pin and VSS(typical 4 s delay with a 3.3 μF capacitor).
Two of the three supplies monitored (VCC1and VCC2) have fixed (customer-selectable, factory-trimmed) thresholds (VRST1and VRST2). The third voltage is monitored using an externally adjustable RSTIN threshold (0.626 V internal reference).
If any of the three monitored voltages drop below its factory-trimmed or adjustable thresholds, or if MRis asserted to logic low, a RSTis asserted (driven low). Once asserted, RSTis maintained at low for a minimum delay period (trec) after ALL supplies rise above their respective thresholds and MRreturns to high. These devices are guaranteed to be in the correct reset output logic state when VCC1and/or VCC2is greater than 0.8 V.
These devices are available in standard 5-pin or 6-pin SOT23 packages.
  • All features

    • Primary supply (VCC1) monitor. Fixed (factory-programmed) reset thresholds: 4.63 V to 1.58 V
    • Secondary supply (VCC2) monitor (STM6717/18/19/20/77/78)
    • Fixed (factory-programmed) reset thresholds: 3.08 V to 0.79 V
    • Tertiary supply monitor (using externally adjustable RSTIN): 0.626 V internal reference
    • RSToutputs (push-pull or open drain); state guaranteed if VCC1or VCC2≥ 0.8 V
    • Reset delay time (trec) on power-up: 13.2 ms, 210 ms, 900 ms (typ)
    • Manual reset input (MR)
    • Optional delayed manual reset input (MRC) with external capacitor (STM6777/78/79/80)
    • Low supply current - 11 μA (typ), VCC1= VCC2 = 3.6 V
    • Operating temperature: –40 °C to 85 °C (industrial grade)
