产品概述
The UCD90910 is a ten-rail I2C / PMBus addressable power-supply sequencer and system-health monitor. The device integrates a 12-bit ADC for monitoring up to 13 power-supply voltage, current, or temperature inputs.Twenty-six GPIO pins can be used for power-supply enables, power-on-reset signals, external interrupts, cascading, or other system functions. Twelve of these pins offer PWM functionality. Using these pins, the UCD90910 offers support for fan control, margining, and general-purpose PWM functions. Fan-control signals can be sent using PMBus commands or generated from one of two built-in fan-control algorithms. PWM outputs combined with temperature and fan-speed measurements provide a complete fan-control solution for up to ten independent fans.The TI Fusion Digital Power designer software is provided for device configuration. This PC-based graphical user interface (GUI) offers an intuitive interface for configuring, storing, and monitoring all system operating parameters.
