Abstract
Dispensers and dispensers having refill units with energy on the refill unit energy sources are disclosed herein. An exemplary dispenser includes a housing, a motor for operating a pump, an object sensor, an auxiliary power source, a receptacle for receiving a refill unit and an energy on the refill receiving receptacle. The dispenser further includes a processor, memory, one or more capacitors, an energy on refill voltage boost circuit, a high power voltage buck circuit and a low power regulator circuit. The low power regulator circuit provides power for at least the processor and the object sensor. The capacitors provide power to the high power voltage buck circuit and the low voltage regulator, and the high voltage buck circuit provides power to operate the motor. A refill unit have an energy on the refill energy source may be inserted into the dispenser.
