Product Summary
The STM809SWX6F is a microprocessor reset Circuit. It is a low-power supervisory device. It used to monitor power supplies. It performs a single function: asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping the STM809SWX6F asserted until VCC has risen above the preset threshold for a minimum period of time (trec).
Parametrics
STM809SWX6F absolute maximum ratings: (1)Storage Temperature (VCC Off):–55 to 150℃; (2)Lead Solder Temperature for 10 seconds:260℃; (3)Input or Output Voltage:–0.3 to VCC +0.3 V; (4)Supply Voltage:–0.3 to 7.0 V; (5)Output Current:20 mA; (6)Power Dissipation:320 mW.
Features
STM809SWX6F features: (1)precision monitoring of 3V, 3.3V, and 5V supply voltages; (2)two output configurations: Push-pull RST Output; (3)140ms reset pulse width (MIN); (4)low supply current - 6μA (TYP); (5)guaranteed RST/RST assertion ; (6)down to VCC = 1.0V; (7)operating temperature:–40℃ to 85℃ (Industrial Grade); (8)lead-free, small SOT23 and SOT143 package.
