Low Power µP Supervisor Circuits  
General Description  
Features  
Precision power supply monitor  
The ASM705 / 706 / 707 / 708 and AS813L are cost effective  
CMOS supervisor circuits that monitors power-supply and  
battery voltage level, and µP/µC operation.  
•4.65V threshold (ASM705/707/813L)  
•4.40V threshold (ASM706/708)  
Debounced manual reset input  
Voltage monitor  
The family offers several functional options. Each device  
generates a reset signal during power-up, power-down and  
during brownout conditions. A reset is generated when the  
supply drops below 4.65V (ASM705/707/813L) or 4.40V  
(ASM706/708). For 3V power supply applications, refer to the  
ASM705P/R/S/T data sheet. In addition, the ASM705/706/813L  
feature a 1.6 second watchdog timer. The ASM707/708 have  
both active-HIGH and active-LOW reset outputs but no  
watchdog function. The ASM813L has the same pin-out and  
functions as the ASM705 but has an active-HIGH reset output.  
A versatile power-fail circuit has a 1.25V threshold, useful in low  
battery detection and for monitoring non-5V supplies. All  
devices have a manual reset (MR) input. The watchdog timer  
output will trigger a reset if connected to MR.
