- Intel® power Intel® MAX® 10 logic
You can select either of the aforementioned power management solutions by using Sw8-3.
LTM2987 or power Intel® MAX® 10 devices are capabale of measuring the voltage, measuring the current, trimming the voltage and sequencing the order at power on and power off. Voltages can be trimmed upto +/- 10%. Communication to these devices is through I2C interface. A Linear Technology power monitor application known as LTPowerPlay is utilized to measure, trim and observe each voltage rail's condition.
