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)

Debounced manual reset input

ꢀ

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.
