Standard 3 V smoke detectors

Worcester, Massachusetts,- 亚博棋牌游戏Allegro MicroSystems to launch a new low current BiCMOS photoelectric smoke detector IC, the IC has a low standby current, average battery life of up to 10 years.The AllegroA5303Device can be used with infrared light room, sensing the light coming from the smoke particles.Networking equipment to realize interconnection, when any equipment to detect smoke, all equipment can sound the alarm.Also integrated in the design of special function, work together to promote product detector and testing.The new device is mainly to the market consumption of smoke alarm.

Optical variable gain amplifier can be directly with the infrared emitter - detector for interaction.Amplifier gain level is determined by two external capacitance, and undertake choosing according to operation mode in the internal.Choose a low gain in standby and timer mode.When the local alarm occurs, the low gain will increase about 45% (internal), to provide a lag.In a key test or standby mode regularly monitor the room light sensitivity with high gain.Built-in oscillator and timing circuit ensures that every 10 s only to detect smoke (including 100 s, which greatly reduces the standby power consumption.In addition, integration of special third-order acceleration sensor solutions, so as to shorten the time of voice alarm, reduce errors trigger at the same time.Light sensitivity chamber shall be regularly monitored, when the sensitivity of two consecutive decline period, will be issued a warning signal.

A5303 adopt thin (< 1.2 mm height) whole 20th pin TSSOP package (0.65 mm) nominal pin spacing.Fog the encapsulated as lead-free packaging, with 100% of tin plating pin frame.
