XC3202B Series
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.
