MAX16064 - Power-Supply Controller

General Description

The MAX16064 is a fully integrated 4-channel digital power-supply controller and monitor IC that can be connected up to four power supplies to provide complete digital configurability.

Key Features

  • an internal temperature sensor providing an additional level of system monitoring. Other features include a reset output and an SMBus™ alert output. Each channel of the MAX16064 includes an accurate 12-bit analog-to-digital converter (ADC) input and a differential amplifier for accurately monitoring and reporting the voltage at the load without being influenced by any difference in ground potentials. An integrated 12-bit digital-to-analog converter (DAC) can margin power supplies and dynamically.

19-4807; Rev 0; 7/09 ±0.3% Accurate, Quad, Power-Supply Controller with Active-Voltage Output Control and PMBus Interface General Description The MAX16064 is a fully integrated 4-channel digital power-supply controller and monitor IC that can be connected up to four power supplies to provide complete digital configurability. By interfacing to the power-supply reference input or feedback node, and the output enable, the MAX16064 takes control of the power supply to provide tracking, soft-start, sequencing, margining, and dynamic adjustment of the output voltage. Power-supply sequencing can be performed autonomously or controlled over the PMBus™ interface. Sequencing is controlled during power-down as well as power-up.
