Nanopower µP Supervisory Circuits with

Manual Reset and Watchdog Timer

General Description

Features

The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–

MAX6869 ultra-low-current (170nA, typ) microprocessor

(µP) supervisory circuits combine voltage monitoring,

watchdog timer, and manual reset input functions in a 5-

pin SOT23 package. These devices assert a reset signal

whenever the monitored voltage drops below the factory-

trimmed reset threshold voltage, manual reset is assert-

ed, or the watchdog timer expires. The reset output

♦ Ultra-Low 170nA (typ) Supply Current

♦ Reset Thresholds from +1.575V to +4.625V in

Approximately 100mV Increments

♦ Six Minimum Reset Timeout Period Options from

10ms to 1200ms

♦ Manual Reset Option

♦ Watchdog Timer Option

remains asserted for a minimum timeout period after V

♦ Pin-Selectable 10ms/150ms (min) Reset Timeout

rises above the reset threshold and manual reset is

deasserted. Factory-trimmed reset threshold voltages

are offered from +1.575V to +4.625V in approximately

100mV increments (see the Threshold Suffix Guide).

Each device is offered with six minimum reset timeout

options, ranging from 10ms to 1200ms.

Period (MAX6861/MAX6862/MAX6863)

♦ Immune to Short V_CCTransients

♦ Guaranteed Reset Valid to V_CC= +1.1V

♦ Three Reset Output Options:

Push-Pull RESET

The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–

MAX6869 are offered in a variety of configurations (see

the Selector Guide). The MAX6854/MAX6855/MAX6856/

MAX6861–MAX6869 provide a manual reset input, MR.

The MAX6864–MAX6869 offer a watchdog timer that

monitors activity at the WDI input to prevent code execu-

tion errors. The MAX6864–MAX6869 offer watchdog

timeout options of 3.3s or 209s (typ). The MAX6861/

MAX6862/MAX6863 feature a pin-selectable reset delay

period of 10ms or 150ms (min). Push-pull active-low,

push-pull active-high, and open-drain active-low reset

outputs are available.

Push-Pull RESET

Open-Drain RESET

♦ No External Components

♦ Small 5-Pin SOT23 Package

♦ Pin Compatible to the TPS3836/TPS3837/TPS3838

(MAX6861/MAX6862/MAX6863)
