Since pull up/pull down resistor has not been connected to IN1 and IN2 pins, it is necessary to connect external resistor
to IN1 and IN2 pins depending on the application.
2)Output pin voltage
Logic levels for OUT1 and OUT2 pins are indicated in the truth table. However, it may be assumed that such logic
levels disable the output circuit to fully turn ON at a low voltage when turning ON or OFF the power supply, thus putting
the output pin into the high impedance state.
3) Power supply monitoring function
This IC has a built-in power supply monitoring function which monitors VCC2 (VCC1) from VCC1 (VCC2). It is
assumed that an abnormal state occurs when VCC2 (VCC1) is controlled by the UVLO function for the period of time
longer than the power supply monitoring time (40µsec (Typ)), and then OUT2 (OUT1) becomes”H”. While power ON,
after the control of the UVLO function is reset as well as VCC1 and VCC2 and the power monitoring time (40µsec
(Typ)) has passed, the logic of IN1 and IN2 is reflected to both OUT1 and OUT2. Until the logic of IN1 and IN2 is
reflected to OUT1 and OUT2, they remain “H”.
4) Under Voltage Lock Out (UVLO) function masking time
This IC provides masking time for the UVLO function to prevent the function from malfunctioning with noises. The
masking time is set to 2.5µsec (Typ). The masking time is applied when the UVLO function is ON. It is not applied when
the UVLO function is OFF.
5) Under Voltage Lock Out (UVLO) function
This IC has a built-in UVLO function to prevent the IC from malfunctioning whenever the power supply voltage drops. It
triggers the UVLO state when VCC1 pin and VCC2 pin are changed to 4.0V (Typ) or less and becomes in operational
state when changed to 4.2V (Typ) or more.
・When VCC2 is 4.2V (Typ) or more and VCC1 pin voltage drops below 4.0V (Typ),the output logic of OUT2 pin
becomes “H” and the output logic of OUT1 pin becomes “H” after the power supply monitoring time has passed.
・When VCC1 is 4.2V (Typ) or more and VCC2 pin voltage drops below 4.0V (Typ), the output logic of OUT1 pin
becomes “H” and the output logic of OUT2 pin becomes “H” after the power supply monitoring time has passed.
・When VCC1 pin voltage is 4.2V (Typ) or more and VCC2 pin voltage changes from 4.0V (Typ) or less to 4.2V (Typ)
or more, the output logic of OUT2 pin changes according to the input logic of input IN2 pin, and the output logic of
OUT1 pin changes according to the input logic of input IN1 pin.
・When VCC2 pin voltage is 4.2V (Typ) or more and VCC2 pin voltage changes from 4.0V (Typ) or less to 4.2V (Typ)
or more, the output logic of OUT1 pin changes according to the input logic of input IN1, and the output logic of OUT2
pin changes according to the input logic of input IN2 pin.

Operational Notes
1.
2.
Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply pins.
Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog
block. 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.
4.
Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
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.
Thermal Consideration
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, increase the
board size and copper area to prevent exceeding the maximum junction temperature rating.
6.
7.
Recommended Operating Conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.
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.
8.
9.
Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
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.
10. 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.
11. 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.

Operational Notes
12. 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.

13. Ceramic Capacitor
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
