PT3617中文资料Hi-sensitivity Hall-effect Latch数据手册Prolific规格书

描述 Description

OVERVIEWThe PT3617 is designed for magnetic actuating using a bipolar magnetic field. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. This Hall effect IC is optimal for DC brushless fan application. The supply voltage range is from 3.8V to 38V and the maximum output current is 50mA. The internal protection device could benefit PT3617 to survive up to -32V in reversed battery situation. This Hall effect sensor IC integrate the sensor, pre-amplifier with dynamic offset cancellation and the hysteresis comparator in single chip.
