Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the
absolute maximum ratings.
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by increasing board size
and copper area so as not to exceed the maximum junction temperature rating.

Description of Operations
(Offset Cancellation)
VDD
The Hall elements are shown with an equivalent
Wheatstone (resistor) bridge circuit. Offset voltage may be
generated by a differential in this bridge resistance, or can
arise from changes of resistance due to package or
bonding stress. A dynamic offset cancellation circuit is
employed to cancel this offset voltage.
I
When the Hall elements are connected as shown in Figure
8 and a magnetic field is applied perpendicular to the Hall
elements, a voltage is generated at the mid-points of the
bridge. This is known as Hall voltage.
B
+
×
Hall Voltage
Dynamic offset cancellation switches the wiring to redirect
the current flow to a 90° angle from its original path, and
thereby cancels the offset voltage of Hall elements.
Only the magnetic signal is maintained in the sample/hold
circuit process and then released.

After VDD power on, the initial state of OUT is High (Hi-Z).
After tPON time pass after VDD exceeds the OFF voltage of Under Voltage Lockout (UVLO), OUT becomes L when the
magnetic field is beyond BOP
.
When VDD is less than ON voltage of UVLO, OUT becomes High (Hi-Z).
Magnet Selection
Neodymium and ferrite are major permanent magnets. Neodymium generally offers greater magnetic power per volume than
ferrite, thereby enabling miniaturization of magnet. The larger neodymium magnet is, the stronger magnetic flux density is.
And the farther detection distance is, the weaker it is. Therefore, the proper size and detection distance of the magnet should
be determined according to the operate point of Hall IC. To increase the magnet’s detection distance, the magnet which is
thicker or larger sectional area is used.

Operational Notes
1. Reverse Connection of Power Supply
This IC has a built-in reverse supply voltage protection circuit that prevents damage to the IC. Do not use in a situation
that exceeds the absolute maximum ratings of built-in reverse supply voltage protection circuit.
2. Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at
all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic
capacitors.
3. Ground Voltage
Except for pins built-in reverse protection, ensure that no pins are at a voltage below that of the ground pin at any time,
even during transient condition.
4. Ground Wiring Pattern
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations
on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.
5. Recommended Operating Conditions
The function and operation of the IC are guaranteed within the range specified by the recommended operating
conditions. The characteristic values are guaranteed only under the conditions of each item specified by the electrical
characteristics.
6. Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow
instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and
routing of connections.
7. Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply
should always be turned off completely before connecting or removing it from the test setup during the inspection
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during
transport and storage.

Operational Notes – continued
8. Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and
unintentional solder bridge deposited in between pins during assembly to name a few.
9. Unused Input Pins
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the
power supply or ground line.
10. Regarding the Input Pin of the IC
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be
avoided.

11. Ceramic Capacitor
When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
12. Thermal Shutdown Circuit (TSD)
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always
be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the
junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF power output pins. When the Tj
falls below the TSD threshold, the circuits are automatically restored to normal operation.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from
heat damage.
13. Over Current Protection Circuit (OCP)
This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This
protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should
not be used in applications characterized by continuous operation or transitioning of the protection circuit.
