MAX6369–MAX6374

Pin-Selectable Watchdog Timers

General Description

Beneﬁts and Features

The MAX6369–MAX6374 are pin-selectable watchdog

timers that supervise microprocessor (μP) activity and

signal when a system is operating improperly. During

normal operation, the microprocessor should repeatedly

toggle the watchdog input (WDI) before the selected

watchdog timeout period elapses to demonstrate that

the system is processing code properly. If the μP does

not provide a valid watchdog input transition before the

timeout period expires, the supervisor asserts a watchdog

(WDO) output to signal that the system is not executing

the desired instructions within the expected time frame.

The watchdog output pulse can be used to reset the μP or

interrupt the system to warn of processing errors.

● Precision Watchdog Timer for Critical μP Applications

● Pin-Selectable Watchdog Timeout Periods

● Pin-Selectable Watchdog Startup Delay Periods

● Ability to Change Watchdog Timing Characteristics

Without Power Cycling

● Open-Drain or Push-Pull Pulsed Active-Low

Watchdog Output

● Watchdog Timer Disable Feature

● +2.5V to +5.5V Operating Voltage

● 8μA Low Supply Current

● No External Components Required

● Miniature 8-Pin SOT23 Package

The MAX6369–MAX6374 are flexible watchdog timer

supervisors that can increase system reliability through

notification of code execution errors. The family offers

several pin-selectable watchdog timing options to match

a wide range of system timing applications:

● AEC-Q100 Qualified (MAX6369KA/V+ and

MAX6374KA/V+ Only)

Applications

● Watchdog startup delay: provides an initial delay

before the watchdog timer is started.

● Embedded Control Systems

● Industrial Controllers

● Critical μP and Microcontroller (μC) Monitoring

● Automotive

● Watchdog timeout period: normal operating watchdog

timeout period after the initial startup delay.

● Watchdog output/timing options: open drain (100ms)

or push-pull (1ms).

● Telecommunications

● Networking

The MAX6369–MAX6374 operate over a +2.5V to +5.5V

supply range and are available in miniature 8-pin SOT23

packages.
