AS443中文资料3.5V~45V, +100/+150G Hall Effect Switch with RPP数据手册Anisem规格书

描述 Description

The AS443 is a Hall-effect sensor unlatch for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.

If a magnetic flux density (B) is larger than operation point (Bop), OUT will turn on (Low). If B
