MAX34409 - SMBus Dual/Quad Current Monitor

Download the MAX34409 datasheet PDF. This datasheet also covers the MAX34408 variant, as both devices belong to the same smbus dual/quad current monitor family and are provided as variant models within a single manufacturer datasheet.

Description

The MAX34408/MAX34409 are two- and four-channel current monitors that are configured and monitored with a standard I2C/SMBus serial interface.

Each unidirectional current sensor offers precision high-side operation with a low full-scale sense voltage.

Features

  • Enables Accurate Current Consumption Measurement on Up to Four Rails with Digital Serial Readout.
  • Low 12.25mV Full-Scale Current-Sense Voltage.
  • Automatic Round Robin Sequencing to Sample Each Current-Sense Input.
  • Selectable Averaging to Improve Current-Sense Accuracy.
  • Programmable Digital Overcurrent Thresholds with Delay Function.
  • I2C/SMBus Interface with Bus Timeout.
  • Register Access to Real-Time Current Measurements.
  • Comp.

MAX34408/MAX34409 EVALUATION KIT AVAILABLE SMBus Dual/Quad Current Monitor General Description The MAX34408/MAX34409 are two- and four-channel current monitors that are configured and monitored with a standard I2C/SMBus serial interface. Each unidirectional current sensor offers precision high-side operation with a low full-scale sense voltage. The devices automatically sequence through two or four channels and collect the current-sense samples and average them to reduce the effect of impulse noise. The raw ADC samples are compared to user-programmable digital thresholds to indicate overcurrent conditions. Overcurrent conditions trigger a hardware output to provide an immediate indication to shut down any necessary external circuitry.
