CST145A Description/概述:
The CST145A is a unipolar hall effect switch sensor,which is for contact less switching applications. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and an open-drain output. The bandgap regulator allows a wide operating voltage range.
CST145A is rated for operating temperature range from -40°C to 150°C and voltage range from 2.7V to 24V.
CST145A是一種單極霍爾效應(yīng)開關(guān)傳感器，用于少接觸開關(guān)應(yīng)用。該設(shè)備包括一個用于磁傳感的片上霍爾電壓發(fā)生器，一個放大霍爾電壓的放大器，一個用于為噪聲抑制提供開關(guān)滯后的施密特觸發(fā)器，以及一個開漏極輸出。帶隙調(diào)節(jié)器允許一個廣泛的工作電壓范圍。
CST145A的額定工作溫度范圍為-40°C到150°C，電壓范圍為2.7V到24V。
