MAX819M +5V Microprocessor Supervisory Circuits

MAX819M Description

19-0494; Rev 1; 3/96 +5V Microprocessor Supervisory Circuits _______________General .
The MAX817/MAX818/MAX819 microprocessor (µP) supervisory circuits simplify power-supply monitoring, battery control, and chip-enable gating in µP syst.

MAX819M Features

* o Precision Supply-Voltage Monitor: 4.65V (MAX81_L) 4.40V (MAX81_M) o 11µA Quiescent Supply Current o 200ms Reset Time Delay o Watchdog Timer with 1.6sec Timeout (MAX817/MAX818) o Battery-Backup Power Switching; Battery Voltage Can Exceed VCC o Battery Freshness Seal o On-Board, 3ns Gating of Chip-E

MAX819M Applications

* The MAX817/MAX818/MAX819 are specifically designed to ignore fast transients on VCC. Other supervisory functions include active-low reset, backupbattery switchover, watchdog input, battery freshness seal, and chip-enable gating. The Selector Guide below lists the specific functions available from e
