UHC188中文资料SINGLE OUTPUT HALL EFFECT LATCH数据手册UTC规格书

描述 Description

UTC UHC188 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device using HVCMOS process includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal band-gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.If a magnetic flux density larger than threshold Bop, OUT is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned off  (high).

特性 Features

3.0V~20V DC operation voltage Temperature compensation Wide operating voltage range Open-Drain pre-driver 25mA maximum sinking output current.
