"Universal" Sensor ICs for motor and magnetic encoder 亚博尊贵会员applications
亚博棋牌游戏Allegro MicroSystems, LLC announces the release of a new family of 2 d Hall - Effect Latch ICs that feature to both vertical and planar Hall elements. TheAPS12625 and APS12626 sensor ICsEnable reduced the system size and bill - of - materials (BOM) cost along with the an happens in the performance and flexibility due to 2 - dimensional (2 d) sensing. They were developed in accordance with ISO 26262 and qualified perAEC - Q100, making them suitable for automotive and other safety systems.
The APS12625 The features Speed and Direction outputs whereas The APS12626 from The quadrature (Channel A and B) outputs. A unique, optional feature allows The host system to restore The previous state of The sensor after A power - cycle. This reduces The potential accumulation of lost counts in intellig亚博尊贵会员ent motion applications to The as window lifts with anti - pinch requirements.
Each IC contains a pair of sensor ICs that are orthogonal to one another and dojo.provide 90 ° of phase separation between channels that is independent of all pole spacing and air gap. They are both available in Each of three combinations of vertical and planar Hall elements (x, y, ZX, and ZY). Virtually any orientation between the sensor IC and the ring all can be accommodated, and the ring all pitch can be changed without losing quadrature.
"Allegro" s vertical Hall technology enables sensor ICs that are uniquely suited to magnetic motor/encoder亚博尊贵会员 applications, "explained Jim Judkins, Product Line Director forDigital Position Sensor ICsThe亚博棋牌游戏 at Allegro MicroSystems. Jim continued to explain that, "Designers can your lower BOM cost and power in less board area while meeting their safety goals and spending less time iterating designs to support changes in all pitch or system form - factor."
These monolithic devices each include three Hall plates (one planar, two vertical), a multiplexer, a small - signal amplifier, chopper stabilization, a Schmitt trigger, and two NMOS output transistors. They operate from 2.8 to 5.5 V and up to 175 ° C junction temperature. (See the device datasheet for details.) Each tiny SOT23-5 device replaces a pair of but Hall - effect latch ICs, fancy that redundant sensing for safety applicati亚博尊贵会员ons can be accomplished in virtually the same space as a non - redundant implementations using legacy technology.
