Texas Instruments recently introduced a 12-channel sequencer and system health manager with fan control and multiphase PWM clock generator.
The UCD90124 integrates system power management and system thermal management into one device, which reduces board space and eases design, while providing highly intelligent system health monitoring. The chip features power supply margining and comprehensive non-volatile error logging, allowing customers to diagnose power supply failures in their systems.
The UCD90124 can sequence and monitor up to 12 power supplies while simultaneously margining up to 10 rails, as well as monitor and control up to four fans. It has a built-in temperature control algorithm that automatically adjusts fan speed based on five configurable temperature zones. Alternatively, designers can use their own temperature control algorithm running on an external host and communicate desired fan speed via I²C commands.
An auto-calibrate function automatically determines the turn on, turn off and maximum duty cycle for the fan, which allows the designer to think in terms of operating speed and also accounts for environmental variables in fan speed. The UCD90124 can generate up to eight clocks with configurable frequencies from 15,259 kHz to 125 MHz and phase shift from 0 to 360°, easing synchronisation of switch-mode power supplies.
TI’s easy-to-use Fusion Digital Power Designer Graphical User Interface (GUI) allows the designer to configure the UCD90124 via a PMBus/I²C interface. The free, downloadable tool simplifies the development process and speeds time-to-market by allowing the designer to configure all device parameters in minutes.
