nanoPower Supervisor and Watchdog Timer

General Description

Benefits and Features

The MAX16152/MAX16153/MAX16154/MAX16155 ultra-

low-current supervisory circuits monitor a single system

supply voltage and the integrity of code execution by a

microprocessor or microcontroller. These supervisors as-

● 400nA (typ) Supply Current

● 1.2V to 5.5V Operating Supply Range

● Monitors Supply Voltage and Provides System Reset

Signal

sert the reset output whenever the V

supply voltage is

● 1.5V to 5.0V Input Threshold Range in 100mV

Increments

● Watchdog Function Detects Faulty Code Execution

● Open-Drain Reset and Watchdog Outputs

● Watchdog Timer Enable Input

● 6-Bump WLP Package

greater than the minimum operating voltage, but less than

the reset threshold. After the supply voltage rises above

the reset threshold, the reset output remains asserted for

the reset timeout period, and then deasserts. Reset volt-

age thresholds are available from 1.50V to 5.0V in approx-

imately 100mV increments.

● 6-Pin SOT23 Package

● -40°C to +125°C Operating Temperature Range

A watchdog timer circuit monitors microprocessor or mi-

crocontroller activity. During normal operation, the micro-

processor or microcontroller should repeatedly toggle the

watchdog input (WDI) before the supervisor’s watchdog

timeout period elapses to confirm that the system is exe-

cuting code properly. If the microprocessor or microcon-

troller 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 code as expected. The watchdog output pulse

can be used to reset the microprocessor or microcon-

troller, or it may be used to interrupt the system to warn of

execution errors. The MAX16152 and MAX16153 feature

a manual reset input (MR) to allow an external pushbutton

or logic signal to initiate a reset pulse. The MAX16154 and

MAX16155 feature a logic input (WD_EN) that allows the

system to enable and disable the watchdog function.
