OCH168/OCH168A
Micro Power, Ultra-sensitive Hall Switch
◼ General Description
The OCH168(OCH168A) is an Integrated Hall effect sensor designed specifically to meet the requirements of low-power devices.
e.
g.
as an On/Off switch in Cellular Flip-Phones, with battery operating
voltages of 2.
4V~ 5.
5V.
Precise magnetic switching points and high temperature stability are achieved through the unique design of the internal circuit.
An onboard clock scheme is used to reduce the average operating current of the IC.
During the operate phase the IC compares the actual magnetic field detected with the internally compensated switching points.
The output is switched at the end of eac...
