The IMP705/706/707/708 and IMP813L CMOS supervisor circuits
monitor power-supply and battery voltage level, and

C operation.
Compared to pin-compatible devices offered by Maxim Integrated
Products, IMP devices feature 60 percent lower maximum supply current.
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.
All devices are available in 8-pin DIP, SO and MicroSO packages.
