Low-Power µP Supervisor Circuits  
– Watchdog timer  
– Brownout detection  
– Power supply monitor  
The IMP705/706/707/708 and IMP813L CMOS supervisor circuits  
monitor power-supply and battery voltage level, and µP/µC operation.  
Compared to pin-compatible devices offered by Maxim Integrated  
Products, IMP devices feature 60 percent lower maximum supply current.  
Key Features  
ꢀ Improved replacements for the Maxim  
MAX705/6/7/8, MAX813L  
– 140µA maximum supply current  
– 60% improvement  
Precision power supply monitor  
– 4.65V threshold (IMP705/707/813L)  
– 4.40V threshold (IMP706/8)

Voltage monitor  
– 1.25V threshold  
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 (IMP705/707/813L) or 4.40V (IMP706/708). For 3V power supply  
applications, refer to the IMP705P/R/S/T data sheet. In addition, the  
IMP705/706/813L feature a 1.6 second watchdog timer. The IMP707/708  
have both active-HIGH and active-LOW reset outputs but no watchdog  
function. The IMP813L has the same pin-out and functions as the IMP705  
but has an active-HIGH reset output. A versatile power-fail circuit has a  
1.25V threshold, useful in checking battery levels and non-5V supplies. All  
devices have a manual reset (MR) input. The watchdog timer output will  
trigger a reset if connected to MR.
