  The POWR1220AT8 can be used to implement a form of Voltage Identification Digital (VID). Typically a processor will output a digital code to the power supply to request more or less power depending on the processor load. When the processor is going ...

• 1433 - Platform Manager/Power Manger II: How do I protect VMON input pins from noise or accidental spikes?

  The absolute maximum input voltage for the VMON input pins is 6V. Any inadvertent stresses beyond this limit will damage the device. Thus, protection circuits (like using a 5.1V shunt Zener diode) are recommended to guard the VMON input pins against ...

  There are several ways to implement multiple Power Manager II devices on a board. In some cases the functions inside a Power Manager II may be stand alone and will not affect the other device controlling different supplies. In cases where there are ...

• 2182 - [Platform Manager 2] Will POR signal be generated when only VCCINP is present and VCCD/VCCA are unavailable, causing a defined state at the OUTx pins?

  For proper operation of asynchronous set/resets of our flip-flops, internal POR generation logic is available. This POR circuitry works by detecting voltage levels of the VCCA, VCCD supply lines. The unavailability of analog and digital supply lines ...

• 1666 - Power Manager II: Can I use the RESETb pin on a POWR1014 or POWR1220 to reset other parts of my circuit?

  The RESETb pin on an ispPAC-POWR1014 or ispPAC-POWR1220 is bidirectional (open drain with internal pull-up). Its primary function is to be used as an input so that one can reset the device after it has been powered up. The secondary function of this ...
