Abstract: A toner cartridge and a printer using the same and a related protection management method are provided. In the present disclosure, by additionally equipping a hardware configuration of identification unit in the toner cartridge, the equipped identification unit would provide a (unique) ID code representing the toner cartridge in response to a setting code (randomly) determined by a controller of the printer. Only when the setting code and the ID code are the same, and when the toners filled inside the toner cartridge are not empty yet, is the printer allowed to normally operate; otherwise, the printer is stopped from using the toner cartridge, and the user is asked to replace a new genuine toner cartridge. Accordingly, it is assured that the internal components of the printer won't be damaged by the unidentified, low-priced dummy toner cartridges, and the print quality and service lifetime of the printer would be maintained.

Abstract: An adaptive switch mode LED driver provides an intelligent approach to driving multiple strings of LEDs. The LED driver determines an optimal current level for each LED channel from a limited set of allowed currents. The LDO driver then determines a PWM duty cycle for driving the LEDs in each LED channel to provide precise brightness control over the LED channels. Beneficially, the LED driver minimizes the power dissipation in the LDO circuits driving each LED string, while also ensuring that the currents in each LED string are maintained within a limited range. A sample and hold LDO allows PWM control over extreme duty cycles with very fast dynamic response. Furthermore, fault protection circuitry ensures fault-free startup and operation of the LED driver.
