Manufacturer:MOTOROLA Description:The traditional procedure for providing hold-up during power loss is to buffer the device with enough bulk capacitance to allow a controlled shutdown to occur or an alternative power source to be brought on line. The problem with this approach is that very large capacitor banks are required because the capacitors are charged at the relatively low voltage at which power fails. |
