Application Information
The system connection diagram shown here gives no guarantee to the operation of the application circuit.
When the recommended external circuit components are changed, be sure to consider adequate margins by taking into
account external parts and/or IC’s dispersion including not only static characteristics, but also transient characteristics.
Functional Description
The BD2270HVF is a driver IC that uses an N-channel MOSFET as a high side load switch. This IC incorporates the
following functions.
1. GATE drive
The gate drive voltage of an N-channel MOSFET is generated by a built-in charge pump in the BD2270HFV. The
built-in charge pump in the BD2270HFV generates a voltage three times as high as the power supply voltage at the
GATE terminal. In addition, since this IC has a built-in capacitor for the charge pump, it needs no external parts.
The charge pump operates when the AEN is set to High. When the AEN is set to Low, the GATE terminal voltage is
fixed to the GND level.
2. Output discharge circuit
The output discharge circuit is enabled when the AEN is set to Low. When the discharge circuit is activated, the 200Ω
(Typ.) MOSFET switch located between the DISC terminal and the GND terminal turns ON. Connecting the DISC
terminal and the source side (load side) of the N-channel MOSFET makes it possible to immediately discharge
capacitive load.
3. Soft start function
When the AEN terminal input voltage reaches the High level, the built-in charge pump in the BD2270HFV charges the
gate of the N-channel MOSFET. The turn-on time of the N-channel MOSFET is determined by the GATE capacity. In
addition, connecting a capacitor to the GATE terminal makes it possible to lengthen the rise of turn-on time of the
N-channel MOSFET, thus achieving reduction of the inrush current to a large capacitive load.
4. Analog control input terminal
The AEN input of the BD2270HFV is connected to the built-in hysteresis comparator. Consequently, even analog
signals can control the BD2270HFV, thus facilitating the control of the switch ON-OFF sequence.

Operational Notes
(1) Absolute Maximum Ratings
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. 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
(2) 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.
(3) 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
terminals.
(4) Power supply line
Design the PCB layout pattern to provide low impedance ground and 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.
(5) Ground Voltage
The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no
pins are at a voltage below the ground pin at any time, even during transient condition.
(6) Short between pins and mounting errors
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation
or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins.
(7) Operation under strong electromagnetic field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
(8) 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.
(9) Regarding input pins 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.

(10) GND wiring pattern
When using both small-signal and large-current GND 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 GND traces of
external components do not cause variations on the GND voltage. The power supply and ground lines
must be as short and thick as possible to reduce line impedance.
(11) External 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.
(12) Thermal consideration
Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in
actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions (Pc≥Pd).

Precaution on using ROHM Products
1.
If you intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1),
aircraft/spacecraft, nuclear power controllers, etc.) and whose malfunction or failure may cause loss of human life,
bodily injury or serious damage to property (“Specific Applications”), please consult with the ROHM sales
representative in advance. Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of any
ROHM’s Products for Specific Applications.

2.
ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3.
Our Products are not designed under any special or extraordinary environments or conditions, as exemplified below.
Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the
use of any ROHM’s Products under any special or extraordinary environments or conditions. If you intend to use our
Products under any special or extraordinary environments or conditions (as exemplified below), your independent
verification and confirmation of product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4.
The Products are not subject to radiation-proof design.
5.
Please verify and confirm characteristics of the final or mounted products in using the Products.
6.
In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7.
De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8.
Confirm that operation temperature is within the specified range described in the product specification.
9.
ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1.
When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2.
In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification

Precaution for Electrostatic
This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper
caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be
applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron,
isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control).
Precaution for Storage / Transportation
1.
Product performance and soldered connections may deteriorate if the Products are stored in the places where:
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2
[b] the temperature or humidity exceeds those recommended by ROHM
[c] the Products are exposed to direct sunshine or condensation
[d] the Products are exposed to high Electrostatic
2.
Even under ROHM recommended storage condition, solderability of products out of recommended storage time period
may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is
exceeding the recommended storage time period.
3.
Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads
may occur due to excessive stress applied when dropping of a carton.
4.
Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of
which storage time is exceeding the recommended storage time period.
