FEATURES
x Design improvement over Maxim MAX690A/692A/802L/802M/805L — 70% lower current than Maxim: 100µA maximum — RESET Operation to 1.1V x Two precision supply-voltage monitor options — 4.65V (IMP690A/802L/805L) — 4.40V (IMP692A/802M) x Battery-backup power switch on-chip x Watchdog timer: 1.6 second timeout x Power failure/low battery detection x Short-circuit protection and thermal limiting x Small 8-pin SO package x No external components x Specified over full temperature range d) 1.25V threshold detector for power loss or general purpose voltage monitoring While these features are pin–compatible with the industry standard power–supply supervisors offered by Maxim, the IMP devices are superior replacements and can reduce power requirements by 70 percent when compared to Maxim MAX690/MAX692A/MAX802L/MAX802M/ MAX805L devices. Short-circuit and thermal protection have also been added. The IMP690A/IMP802L/IMP805L generate a reset pulse when the supply voltage drops below 4.65V, and the IMP692A/IMP802M generate a reset below 4.40V.
