Mounted on a FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%).
The voltage difference between inverting input and non-inverting input is the differential input voltage.
Then input pin voltage is set to more than VSS.
(Note 6) An excessive input current will flow when input voltages of more than VDD+0.6V or less than VSS-0.6V are applied.
The input current can be set to less than the rated current by adding a limiting resistor.
Caution: 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.

Datasheet
Description of Electrical Characteristics
Described below are descriptions of the relevant electrical terms used in this datasheet. Items and symbols used are also
shown. Note that item name and symbol and their meaning may differ from those on another manufacturer’s document or
general document.
1. Absolute Maximum Ratings
Absolute maximum rating items indicate the condition which must not be exceeded. Application of voltage in excess of absolute
maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of characteristics.
(1) Supply Voltage (VDD/VSS)
Indicates the maximum voltage that can be applied between the VDD terminal and VSS terminal without
deterioration or destruction of characteristics of internal circuit.
(2) Differential Input Voltage (VID)
Indicates the maximum voltage that can be applied between non-inverting and inverting terminals without damaging
the IC.
(3) Input Common-mode Voltage Range (VICM)
Indicates the maximum voltage that can be applied to the non-inverting and inverting terminals without deterioration
or destruction of electrical characteristics. Input common-mode voltage range of the maximum ratings does not assure
normal operation of IC. For normal operation, use the IC within the input common-mode voltage range characteristics.
(4) Power Dissipation (PD)
Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25°C
(normal temperature). As for package product, PD is determined by the temperature that can be permitted by the IC in
the package (maximum junction temperature) and the thermal resistance of the package.
2. Electrical Characteristics
(1) Input Offset Voltage (VIO)
Indicates the voltage difference between non-inverting terminal and inverting terminals. It can be translated into the
input voltage difference required for setting the output voltage at 0 V.
(2) Input Offset Current (IIO)
Indicates the difference of input bias current between the non-inverting and inverting terminals.
(3) Input Bias Current (IB)
Indicates the current that flows into or out of the input terminal. It is defined by the average of input bias currents at
the non-inverting and inverting terminals.
(4) Supply Current (IDD)
Indicates the current that flows within the IC under specified no-load conditions.
(5) Maximum Output Voltage(High) / Maximum Output Voltage(Low) (VOH/VOL)
Indicates the voltage range of the output under specified load condition. It is typically divided into maximum output
voltage high and low. Maximum output voltage high indicates the upper limit of output voltage. Maximum output
voltage low indicates the lower limit.
(6) Large Signal Voltage Gain (AV)
Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting terminal
and inverting terminal. It is normally the amplifying rate (gain) with reference to DC voltage.
AV = (Output voltage) / (Differential Input voltage)
(7) Input Common-mode Voltage Range (VICM)
Indicates the input voltage range where IC normally operates.
(8) Common-mode Rejection Ratio (CMRR)
Indicates the ratio of fluctuation of input offset voltage when the input common mode voltage is changed. It is
normally the fluctuation of DC.
CMRR = (Change of Input common-mode voltage)/(Input offset fluctuation)
(9) Power Supply Rejection Ratio (PSRR)
Indicates the ratio of fluctuation of input offset voltage when supply voltage is changed.
It is normally the fluctuation of DC.
PSRR = (Change of power supply voltage)/(Input offset fluctuation)
(10) Output Source Current/Output Sink Current (ISOURCE / ISINK)
The maximum current that can be output from the IC under specific output conditions. The output source current
indicates the current flowing out from the IC, and the output sink current indicates the current flowing into the IC.
(11) Output Rise Time/Output Fall Time (tR / tF)
Indicates the time required for an output voltage step to change from 10% to 90% of its final value.
(12) Rising Propagation Delay Time/Falling Propagation Delay Time (tPLH / tPHL)
Indicates the time to reach 50% of the output voltage after the step voltage is applied at the input pin.

Power Dissipation
Power dissipation (total loss) indicates the power that the IC can consume at TA=25°C (normal temperature). As the IC
consumes power, it heats up, causing its temperature to be higher than the ambient temperature. The allowable
temperature that the IC can accept is limited. This depends on the circuit configuration, manufacturing process, and
consumable power.
Power dissipation is determined by the allowable temperature within the IC (maximum junction temperature) and the
thermal resistance of the package used (heat dissipation capability). Maximum junction temperature is typically equal to the
maximum storage temperature. The heat generated through the consumption of power by the IC radiates from the mold
resin or lead frame of the package. Thermal resistance, represented by the symbol θJA°C/W, indicates this heat dissipation
capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance.
Figure 49(a) shows the model of the thermal resistance of a package. The equation below shows how to compute for the
Thermal resistance (θJA), given the ambient temperature (TA), maximum junction temperature (TJmax), and power dissipation
(PD).
θJA = (TJmax-TA) / PD °C/W
The Derating curve in Figure 49(b) indicates the power that the IC can consume with reference to ambient temperature.
Power consumption of the IC begins to attenuate at certain temperatures. This gradient is determined by Thermal
resistance (θJA), which depends on the chip size, power consumption, package, ambient temperature, package condition,
wind velocity, etc. This may also vary even when the same of package is used. Thermal reduction curve indicates a
reference value measured at a specified condition. Figure 49(c) to (f) shows an example of the derating curve for BU7251G,
BU7251SG, BU7252xxxx, and BU7252Sxxx.

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.
2.
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.
Ground Voltage
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.
Thermal Consideration
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in
deterioration of the properties of the chip. The absolute maximum rating of the PD stated in this specification is when
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum
rating, increase the board size and copper area to prevent exceeding the PD rating.
6.
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.
7.
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.
Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9.
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 – continued
12.
Regarding the Input Pin of the IC
In the construction of this IC, P-N junctions are inevitably formed creating parasitic diodes or transistors. The
operation of these parasitic elements can result in mutual interference among circuits, operational faults, or physical
damage. Therefore, conditions which cause these parasitic elements to operate, such as applying a voltage to an
input pin lower than the ground voltage should be avoided. Furthermore, do not apply a voltage to the input pins when
no power supply voltage is applied to the IC. Even if the power supply voltage is applied, make sure that the input pins
have voltages within the values specified in the electrical characteristics of this IC.
13.
Unused circuits
When there are unused comparators, it is recommended that they are
connected as in Figure 49, setting the non-inverting input terminal to a
potential within the in-phase input voltage range (VICM).
14.
Input Voltage
Applying VDD +0.3V to the input terminal is possible without causing
deterioration of the electrical characteristics or destruction, regardless of
the supply voltage. However, this does not ensure normal circuit
operation. Please note that the circuit operates normally only when the
input voltage is within the common mode input voltage range of the
electric characteristics.
VDD
VSS
Figure 49. Example of Application Circuit
for Unused Comparator
15.
Power Supply(single/dual)
The voltage comparator operates when the voltage supplied is between VDD and VSS. Therefore, the single supply
voltage comparator can be used as dual supply voltage comparator as well.
16.
Output capacitor
If a large capacitor is connected between the output pin and VSS pin, current from the charged capacitor will flow into
the output pin and may destroy the IC when the VDD pin is shorted to ground or pulled down to 0V. Use a capacitor
smaller than 0.1µF between output pin and VSS pin.
17.
Oscillation by output capacitor
Please pay attention to the oscillation by output capacitor and in designing an application of negative feedback loop
circuit with these ICs.
18.
Latch Up
Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur latch up and
protect the IC from abnormaly noise.
