STM6905TZCDS6F(2008) Даташит - STMicroelectronics

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.

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
■ RST output (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)
