125°C OPERATIONHIGH-WITHSTAND VOLTAGE HIGH-SPEEDBIPOLAR HALL EFFECT LATCH IC
Rev.1.1_00© ABLIC Inc., 2016-2021

This IC, developed by CMOS technology, is a bipolar Hall effect latch IC with high-withstand voltage, high-speed detection
and high-accuracy magnetic characteristics.
The output voltage changes when this IC detects the intensity level of magnetic flux density and a polarity change. Using
this IC with a magnet makes it possible to detect the rotation status in various devices. This IC includes an output current
limit circuit.
High-density mounting is possible by using the small SOT-23-3S package.
Due to its high-accuracy magnetic characteristics, this IC can make operation's dispersion in the system combined withmagnet smaller.
ABLIC Inc. offers a "magnetic simulation service" that provides the ideal combination of magnets and our Hall effect ICs forcustomer systems. Our magnetic simulation service will reduce prototype production, development period and development
costs. In addition, it will contribute to optimization of parts to realize high cost performance.
For more information regarding our magnetic simulation service, contact our sales representatives.

*1. BOP: Operation point
BOP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density applied
to this IC by the magnet (S pole) is increased (by moving the magnet closer).
VOUT retains the status until a magnetic flux density of the N pole higher than BRP is applied.
*2. BRP: Release point
BRP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density applied
to this IC by the magnet (N pole) is increased (by moving the magnet closer).
VOUT retains the status until a magnetic flux density of the S pole higher than BOP is applied.
*3. BHYS: Hysteresis width
BHYS is the difference of magnetic flux density between BOP and BRP.
RemarkThe unit of magnetic flux density mT can be converted by using the formula 1 mT = 10 Gauss.

3. Basic operation
This IC changes the output voltage (VOUT) according to the level of the magnetic flux density and a polarity change (Npole or S pole) applied by a magnet.
3. 1 Product with VOUT = "L" at S pole detection
When the magnetic flux density of the S pole perpendicular to the marking surface exceeds the operation point(BOP) after the S pole of a magnet is moved closer to the marking surface of this IC, VOUT changes from "H" to "L".
When the N pole of a magnet is moved closer to the marking surface of this IC and the magnetic flux density of the
N pole is higher than the release point (BRP), VOUT changes from "L" to "H". In case of BRP < B < BOP, VOUT retains
the status. Figure 13 shows the relationship between the magnetic flux density and VOUT.

Figure 15 shows the operation timing at power-on.
The initial output voltage at rising of power supply voltage (VDD) is either "H" or "L".
In case of B > BOP (operation point) or B < BRP (release point) at the time when the start up time (tPON) is passed afterrising of VDD, this IC outputs VOUT according to the applied magnetic flux density.
In case of BRP < B < BOP at the time when tPON is passed after rising of VDD, this IC maintains the initial output voltage.

 Precautions• If the impedance of the power supply is high, the IC may malfunction due to a supply voltage drop caused by feedthrough current. Take care with the pattern wiring to ensure that the impedance of the power supply is low.
• Note that the IC may malfunction if the power supply voltage rapidly changes. When the IC is used under theenvironment where the power supply voltage rapidly changes, it is recommended to judge the output voltage of the IC
by reading it multiple times.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• Although this IC has a built-in output current limit circuit, it may suffer physical damage such as product deterioration
under the environment where the absolute maximum ratings are exceeded.
• The application conditions for the power supply voltage, the pull-up voltage, and the pull-up resistor should not exceed
the power dissipation.
• Large stress on this IC may affect the magnetic characteristics. Avoid large stress which is caused by the handlingduring or after mounting the IC on a board.
• ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products
including this IC of patents owned by a third party.
