Features  
Description  
• Feature  
The FM811/FM812 is a low cost microprocessor supervisory  
circuit that asserts a reset if the power supply drops below a  
designated threshold or the manual reset pin is forced low.  
Several different reset thresholds are available to  
• Precision Voltage Monitor for 3V, 3.3V or 5V Power  
Supplies  
• 6µA Supply Current  
• 140ms Minimum Reset Pulse Width  
• RESET Remains Valid with VCC as Low as 1.4V  
• Active Low Manual Reset Input  
• No External Components  
• 4-Pin SOT-143 Package  
accommodate systems operating at 3V, 3.3V or 5V.  
The FM811 has an active low RESET output, while the  
FM812 offers an active high RESET output. The reset output  
is guaranteed to remain asserted for a minimum of 140ms  
after VCC has risen above the designated reset threshold.  
The FM811/FM812 is available in a 4-pin SOT-143.  
Applications  
• Critical Microprocessor Power Monitoring  
• Portable Equipment  
• Intelligent Instruments  
• Computers & Printers  
• Controllers
