Concise LED lighting single chip solutions

亚博棋牌游戏Allegro MicroSystems, LLC to launch a new integrated hall effect switch of small power LED driver IC APS13568, small new products of electrical engineering design, a small amount of additional components, and lower overall cost can be realized is compact, simple, reliable, and fault tolerant design of LED lighting.APS13568 single chip solution integrated with micro power voltage regulator, Hall element (Hall plate), small signal amplifier, chopping voltage regulator, Schmitt trigger, open the Hall effect switch, output polarity selection and with soft on/off and the recovery of short circuit/overheating protection of LED drive.The integrated solid hall effect switch support silent, sealing, non-contact activation design, relative to the prone to failure had A significant improvement in the reliability of the mechanical switch, and have very low standby current (25 mu A).

APS13568 LED the drive to achieve low noise, adjustable linear drive, can provide for one or more LED drive current of 150 ma.Optional external capacitor can carry on the programming to the on/off rate, so as to realize the "theater" elegant effect, it is controlled by the hall effect switch, can according to the magnetic field and open and close.Hall effect switch is the very type devices, able to respond to the south, the north magnetic pole), has a high sensitivity (BOP = 40 g), can support a variety of mechanical configuration as well as a variety of shells with different air gap and mechanical deviation degree.APS13568 with optional output polarity and used to connect an additional external circuit open drain output.

APS13568 adds an external output, and can work under 25 mu A small power, the new device added Allegro company's existing LED drive and hall effect switch product portfolio, its target markets include consumer electronics, white goods, shipping, recreational vehicle (RV), motorcycle, etc., as well as the glove box, instrument panel, toilet glass, trunk (trunks/boots), such as the car and truck bed auxiliary automotive lighting applications.APS13568 integrated micro power voltage regulator can be work under 7 v to 24 v power supply voltage, when the disable output consumes only a very low average power supply current.APS13568 are integrated with Zener clamp (Zener clamps), output short circuit protection, thermal shut off and reverse battery protection function, in order to enhance reliability and electromagnetic compatibility (EMC).Eliminated by using dynamic migration technique, can reduce because of the device package usually forming (overmolding), temperature drift and thermal stress caused by disturbance voltage, thus it can be make the hall switch has a better performance.

APS13568 device has two types: type "K" for car level (in line with the AEC - Q100) devices, can be in to 40 ℃ to + 125 ℃ temperature range;"E" type suitable for work in 40 ℃ to + 85 ℃ of industrial and consumer applications.Both models are accord with RoHS standard, USES the SOIC - 8 with high heat dissipation performance surface-mount package (code "LJ").
