SENT輸出的霍爾效應(yīng)線性傳感器

HAL283x產(chǎn)品是 Micronas varioHAL? (HAL 28xy)可編程線性霍爾效應(yīng)傳感器系列的成員。\n產(chǎn)片帶有數(shù)碼SENT（單邊緣蠶食傳輸）界面。該界面支持在惡劣環(huán)境下汽車應(yīng)用的快速和穩(wěn)定的數(shù)據(jù)傳輸。該界面的應(yīng)用符合SAE J2716 SENT 標準2010-01版。\n每條SENT信息含有一系列的脈沖。在一個協(xié)議里，傳感器傳輸磁場信息，傳感器狀態(tài)信息，以及基于安全考量的CRC校驗和。也可選擇在每個協(xié)議里加一個停頓脈沖實現(xiàn)同步傳輸。\n內(nèi)部的數(shù)字信號處理是產(chǎn)品的一大優(yōu)勢，因為模擬偏置、溫度飄移和機械應(yīng)力并不降低傳感器的精度。\n諸如磁場范圍，敏感度，偏置和溫度系數(shù)等主要特性在 ·High-precision linear Hall-effect sensor\n·Output resolution up to 16 bit\n·On-board diagnostics and power-on self-test covering memory and full signal path\n·Typical magnetic ranges from ±20 mT up to ±160 mT in 20 mT steps\n·Programmable temperature compensation sensitivity (2nd order) and offset ;
