WWW.ORIENT-CHIP.COM OCH181 Micro-power, High Sensitivity, Bipolar Detection Type Hall-IC ◼ General Description The OCH181 developed using CMOS technology, is a bipolar detection type Hall IC with a high-sensitivity that operates on a low current. In the Hall IC, a Hall element, an offset cancel circuit, an amplifier circuit, a sample and hold circuit, a Schmidt circuit, and output stage FET are integrated on a single chip housed in a small package by IC technique. The output voltage changes when the OCH181 detects the intensity level of flux density and a polarity change. Using the OCH181 with a magnet makes it possible to detect rotation in various devices. The OCH181 is available in DFN2020-6L packages. Operating temperature range of the OCH181 is from -40°C to 85°C. ◼ Features ⚫ Micro-power consumption ideal for battery-powered applications ⚫ High sensitivity ⚫ Input Voltage low to 2.2V ⚫ Chopper stabilized amplifier stage ⚫ Good RF noise immunity ⚫ Small packag.
