OCH145A Unipolar Hall Effect Switch Sensor
The OCH145A 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-collector output. The bandgap regulator allows a wide operating voltage range. OCH145A is rated for operating temperature range from -40°C to 150°C and voltage range from 2.8V to 24V.
■ Features:
● Wide operating voltage range: 2.8V~24V;
● Operating Temperature: -40°C~+150°C;
● Maximum output sink current: 25mA;
● Reverse polarity protection;
● Open-Drain pre-driver output;
● Package: SIP-3L、SOT23-3L.
■ Applications:
● RPM Detection;
● Speed measurement;
● Non-Contact Switch;
● Position Control;
● Revolution Detection;
● Textile Control System.
