Description
The STM6904 supervisor is a low voltage/low supply current processor supervisor, designed to monitor up to four system power supply voltages. This device is targeted at applications such as “Set-Top Boxes” (STBs), portable, battery-powered systems, networking and communication systems.
Features
◾ Quad voltage monitoring
◾ Accurate ±1.8% across temperature voltage
threshold (±1% at 25 °C)
◾ Primary supply (VCC) monitor. Fixed (factory -
programmed) reset thresholds: 3.078
to 2.188 V
◾ Second fixed (V2IN) monitor. Fixed (factory-
programmed) reset thresholds: 2.333
to 1.110 V
◾ Two additional adjustable supply monitor
inputs (externally adjustable)
◾ 0.6 V internal reference
◾ RST output (open drain)
◾ Output guaranteed for VCC ≥ 0.8 V
◾ Reset delay time (tREC) pin selectable
◾ Manual reset input (MR)
◾ Low supply current of 12 µA (typ)
◾ Power supply voltage 0.8 to 5.5 V
◾ RoHS compliant (green package)
◾ 8-pin MSOP/TSSOP
◾ Operating temperature: –40 to 85 °C (industrial
grade)
Applications
◾ Set-top boxes
◾ Multi-voltage systems
◾ Cable/satellite applications
◾ Computer systems
◾ Data storage equipment
