ETR2602-005a
Low Power Consumption Hall IC (Magnetic Sensor)
■GENERAL DESCRIPTIO N
The XC3202B series is a Hall effect magnetic sensor IC with a built-in CMOS output driver. The device features low power
consumption and small packaging which is ideally suited fo r battery powered portable applications s uch as mobile phones,
electronic dictionaries and handheld game consoles. When the magnetic flux density is higher than the operating point
(Bop), the Low level signal is output. The High level signal is output when the mag netic flux density is lower than the
release point (Brp).

(*2) For supply current, detection time, and detection period, please refer to the below.
The Hall IC is operated intermittently to reduce supply current.
Measurement is done during detection time, in the rest period sensing circuits of Hall plate and latch are turned off to minimize the current.

* Characteristics Values are guaranteed in design. The values may be affected by the conditions such as temperature and mounting.
●Magnetic field and detect surface
The IC Hall plates detect the perpendicular magnetic field so that IC surface should be placed in a
direction perpendicular to the magnetic field.

*1: When the magnetic flux density to the IC becomes larger than Bop, the IC goes into an on-state and outputs a low signal (V
leading edge of the next “tawake” pulse.
*2: When the magnetic flux density to the IC becomes lower than Brp, the IC goes into an off-state and outputs a high signal (V
leading edge of the next “tawake” pulse.
During the other periods, the previous state is maintained.
