Four- to Seven-Input Industrial Power System

MAX42500

Monitor Family

Benefits and Features

General Description

The MAX42500 is a system-on-a-chip (SoC) power

system monitor with up to seven voltage monitor inputs.

•

Small Solution

• 2.35V to 5.50V Operating Supply Voltage

• Only One External Component Required

• 150μA Operating Current

Each

input

has

programmable

overvoltage

(OV)/undervoltage (UV) thresholds of between 2.5%

and 10% with ±1.3% accuracy over the full temperature

range. Two of the inputs have a separate remote

ground-sense input and support dynamic voltage scaling

(DVS) through the integrated I²C interface.

• 8μA Power-Down Mode

High Precision

• Selectable 102.5% to 110% OV Monitors

• Selectable 97.5% to 90% UV Monitors

• Programmable UV and OV Thresholds

• ±1.0% Accuracy (-40°C to +85°C)

• ±1.3% Accuracy (-40°C to +125°C)

• 0.5% Step Size

The MAX42500 contains a programmable flexible power

sequence recorder (FPSR). This recorder stores power-

up and power-down timestamps separately, and

supports on/off and sleep/standby power sequences.

The MAX42500 also contains

programmable

•

Highly Integrated

challenge/response watchdog, which is accessible

through the I²C interface along with a configurable

RESET output.

• Five Fixed-Voltage Monitoring Inputs

• Two Differential DVS Tracking-Voltage

Monitoring Inputs with Remote Ground Sense

• Power-Sequencing Recording

• Simple or Challenge/Response Windowed

Watchdog

The MAX42500 improves reliability while significantly

reducing system size and component count as

compared to separate ICs or discrete components. The

MAX42500 is suitable for use in safety functions up to

SIL 3. The device is designed to operate over the

ambient temperature range of -40°C to +125°C.

• Fault Recording

• Cyclic Redundancy Check (CRC) on I²C Interface

• Programmable I²C Address

• OTP Configuration with Error-Correcting Code

and Reload Functionality

• Programmable Active Low RESET Pin

Key Applications

•

Industrial Process Control

Robotics

Remote Sensor Modules

Power System Supervision

Microcontroller Unit (MCU)/SoC Monitoring

•

16 Pin TQFN with Exposed Pad (3mm x 3mm)

Ongoing Certification Process to IEC 61508 SIL 3

-40°C to +125°C Operating Temperature
