OCH145

WWW.ORIENT-CHIP.COM OCH145 Unipolar Hall Effect Digital Switches For High Temperature ◼ General Description OCH145 is a switched Hall-Effect IC, which is for contactless 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. OCH145 is rated for operating temperature range from -40°C to 150°C and voltage range from 3.8V to 18V. OCH145 are capable of continuous 25mA sinking out and maybe cycled as high as 50mA maximum. ◼ Features ⚫ Unipolar Hall Effect Switch Sensor ⚫ Wide operating voltage range: 3.8V~18V ⚫ Open Collector Pre-Driver ⚫ Maximum output sink current: 50mA ⚫ Chip Power Reverse-Connection Protection ⚫ Operating Temperature: -40℃~+150℃ ⚫ Small Size Package: SIP-3L，SSIP-3L ◼ Applications ⚫ Non-Cont...
