... POWER MANAGEMENT Description The SC2615 is a fully integrated, Three in One, Linear DDR power solution providing power for the VDDQ and the VTT rails. The SC2615 completely adheres to the ACPI sleep state power requirements per Intel motherboard specifications. A linear regulator controller provides the high current of the VDDQ during S0, via an external Power MOSFET, while an internal 1 ...

... VDDQ regulator. Reset/restart The SS/EN pin must be pulled low and high again to restart the SC2615. This can be achieved by cycling the input supplies, 3.3VCC/12VCC. There is a 50mV Hysteresis on the UVLO threshold. When the rails are near the UVLO thresholds possible for noise to trigger the UVLO ...

... UVLO thresholds. Thermal Shutdown There are three independent Thermal Shutdown protection circuits in the SC2615, the VDDQ linear regulator the VTT source regulator, and the VTT sink regulator. If any of the three regulators’ temperature rises above the threshold, that regulator will turn off independently, until the temperature falls below the thermal shutdown limit ...
