SOT23, Low-Power µP Supervisory Circuits

with Battery Backup and Chip-Enable Gating

General Description

The MAX6365–MAX6368 supervisory circuits simplify

power-supply monitoring, battery-backup control func-

tions, and memory write protection in microprocessor

(µP) systems. The circuits significantly improve the size,

accuracy, and reliability of modern systems with an ultra-

small integrated solution.

These devices perform four basic system functions:

1) Provide a µP reset output during V

supply power-

up, power-down, and brownout conditions.

2) Internally control V

to backup-battery switching to

maintain data or low-power operation for CMOS

RAM, CMOS µPs, real-time clocks, and other digital

logic when the main supply fails.

3) Provide memory write protection through internal

chip-enable gating during supply or processor faults.

4) Include one of the following options: a manual reset

input (MAX6365), a watchdog timer function

(MAX6366), a battery-on output (MAX6367), or an

auxiliary user-adjustable reset input (MAX6368).

The MAX6365–MAX6368 operate from V

supply volt-

ages as low as 1.2V. The factory preset reset threshold

voltages range from 2.32V to 4.63V (see the

Ordering

Information).

In addition, each part is offered in three

reset output versions: push-pull active low, open-drain

active low, or open-drain active high (see the

Selector

Guide).

The MAX6365–MAX6368 are available in minia-

ture 8-pin SOT23 packages.

*These

parts offer a choice of reset threshold voltages. From the

Reset Threshold Ranges table, insert the desired threshold volt-

age code in the blank to complete the part number. SOT parts

come in tape and reel only and must be ordered in 2500-piece

increments. See Device Marking Codes for a complete parts list,

including SOT top marks and standard threshold versions. See

Selector Guide for a listing of device features.

Devices are available in both leaded and lead(Pb)-free packaging.

Specify lead-free by replacing “-T” with “+T” when ordering.

-Denotes

a package containing lead(Pb).

= Tape and reel.

/V Denotes an automotive qualified part.

Typical Operating Circuit appears at end of data sheet.
