The MAX817/MAX818/MAX819 microprocessor (µP)

supervisory circuits simplify power-supply monitoring,

battery control, and chip-enable gating in µP systems

b y re d uc ing the numb e r of c omp one nts re q uire d .

These devices are designed for use in +5V-powered

systems. Low supply current (11µA typical) and small

package size make these devices ideal for portable

applications. The MAX817/MAX818/MAX819 are specif-

♦ Precision Supply-Voltage Monitor:

4.65V (MAX81_L)

4.40V (MAX81_M)

♦ 11µA Quiescent Supply Current

♦ 200ms Reset Time Delay

♦ Watchdog Timer with 1.6sec Timeout

(MAX817/MAX818)

ically designed to ignore fast transients on V . Other

♦ Battery-Backup Power Switching; Battery Voltage

supervisory functions include active-low reset, backup-

battery switchover, watchdog input, battery freshness

seal, and chip-enable gating. The Selector Guide below

lists the specific functions available from each device.

Can Exceed V

♦ Battery Freshness Seal

♦ On-Board, 3ns Gating of Chip-Enable Signals

These devices offer two pretrimmed reset threshold volt-

ages for ±5% or ±10% power supplies: 4.65V for the L

versions and 4.40V for the M versions. The MAX817/

MAX818/MAX819 are available in space-saving µMAX

packages, as well as 8-pin DIP/SO.

(MAX818)

♦ Uncommitted Voltage Monitor for Power-Fail or

Low-Battery Warning (MAX817/MAX819)

♦ Manual Reset Input (MAX819)
