APS12170LLHALX傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）規(guī)格書PDF中文資料

APS12170LLHALX屬于傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）。由Allegro MicroSystems制造生產(chǎn)的APS12170LLHALX磁性傳感器 - 開關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來檢測是否存在超過某個特定幅度和/或標(biāo)示的磁場，并提供指示是否存在此類磁場的雙態(tài)輸出。它們與磁簧開關(guān)以及線性或羅盤型固態(tài)器件不同，前者通過使用移動機械部件來提供類似的功能，后者提供指示所施加磁場的強度和/或方向的可變輸出。

DESCRIPTION

The APS12170 is a two-wire, planar Hall-effect sensor

integrated circuit (IC) operating under a continuous-time

sensing architecture. The devices are extremely fast responding

with lower levels of emissions (EMI) than a design using

chopper stabilization.

This Hall-effect latch IC features extended AEC-Q100

qualification and is ideal for high-temperature operation up to

175°C junction temperatures. In addition, the APS12170 includes

a number of features designed specifically to maximize system

robustness, such as reverse-battery protection, overvoltage,

and EMC protection.

A south pole and a north pole of sufficient strength are both

necessary to actuate the device. The devices include on-board

transient protection for all pins, permitting operation directly

from a vehicle battery or regulator with supply voltages from

3.8 to 16 V.

Two package styles provide a choice of through-hole or surface

mounting. Package type LH is a modified 3-pin SOT23W

surface-mount package, while UA is a three-pin ultramini SIP

for through-hole mounting. Both packages are lead (Pb) free

and RoHS compliant, with 100% matte-tin-plated leadframes.

APPLICATIONS

? Seat/window motors

? Sun roof/convertible top/liftgate/tailgate actuation

? Automotive and industrial safety systems
