研發成果介紹
Ballast IC：
	The M8145 is a fully integrated, fully protected ballast control IC designed to drive all types of fluorescent lamps. The M8145 features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, programmable over-current protection, and programmable end-of-life protection. Comprehensive protection features such as protection from failure of a lamp to strike, filament failures, end-of-life protection, DC bus under voltage reset as well as an automatic restart function, have been included in the design.
PFC：
	The M8128 provides simple and high performance active power factor correction. The M8128 provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable to ensure safe operation during AC brownouts. An innovative multi-vector error amplifier is built in to provide rapid transient response and precise output voltage clamping. A built in circuit will disable the controller if the output feedback loop is opened.
Alarm：
	The M75210 is a very low-power IC providing all of the required features for a photoelectric type smoke detector. It is designed for operate at supply voltage as low as 2.7V and suited to 3V Lithium battery powered application. A variable-gain photo amplifier can be directly interfaced to an infrared emitter / detector pair. The amplifier gain levels are determined by two external capacitors that are then internally selected depending on the operating mode. Low gain is selected during standby. During a local alarm this low gain is increased (internally) by ~ 10% to reduce false triggering. High gain is used during the push-button test and during standby to periodically monitor the chamber sensitivity. The internal oscillator and timing circuitry keeps standby power to a minimum by sensing for smoke every 10 seconds in a 100 μs window.
