Technical Note
●Description of operations
VCC
BD4153FV/EFV has an independent power input pin for an internal circuit operation in order to activate UVLO, Input logic,
and charge pump, the maximum current through which is rated to 2 mA. It is recommended to connect a bypass capacitor
of 0.1 μF or so to VCC pin.
EN
With an input of 2.3 volts or higher, this terminal turns to “High” level to activate the circuit, while it turns to “Low” level to
deactivate the circuit (with the standby circuit current of 35 μA), discharges each output and lowers output voltage If the input
is lowered to 0.8 volts or less.
V3_IN, V15_IN, and V3AUX_IN
These are the input terminals for each channel of a 3ch switch. V3_IN and V15_IN terminals have two pins each, which
should be short-circuited on the pc board with a thick conductor. And V3AUX IN terminal should be short-circuited to VCC
terminal. Through these three terminals, a big current runs (V3_IN: 1.35A, V3AUX_IN: 0.275 A, and V15_IN: 0.625 A). In
order to lower the output impedance of the power supply to be connected, it is recommended to provide ceramic capacitors
(of B-characteristics or better) between these terminals and ground; 1 μF or so between V3_IN and GND and between
V15_IN and GND, and 0.1 μF or so between V3AUX_IN and GND.
V3, V15, and V3AUX
These are the output terminals for each switch. V3 and V15 terminals have two pins each, which should be short-circuited
on the pc board and connected to an ExpressCard connector with a thick conductor as shortest as possible. In order to
stabilize the output, it is recommended to provide ceramic capacitors (of B-characteristics or better) between these terminals
and ground; 10 μF or so between V3 and GND and between V15 and GND, and 1 μF or so between V3AUX and GND.
CPPE#
The pin used to find whether a PCI-Express signal compatible card is provided or not. Turns to “High” level with an input of
2.3 volts or higher, which means that no card is provided, while it turns to “Low” level when the input is lowered to 0.8 volts or
less, which means that a card is provided. Controls turning ON/OFF of the switch according to the status of the system.
CPUSB#
The pin used to find whether a USB2.0 signal compatible card is provided or not. Turns to “High” level with an input of 2.3
volts or higher, which means that no card is provided, while it turns to “Low” level when the input is lowered to 0.8 volts or
less, which means that a card is provided. Controls turning ON/OFF of the switch according to the system status.
SYSR
The pin used to detect the system status. Turns to “High” level with an input of 2.3 volts or higher, which means that the
system is activated, while it turns to “Low” level when the input is lowered to 0.8 volts or less, which means that the system is
on standby.
PERST_IN#
The pin used to control a reset signal to a card (PERST#) from the system side. (Also referred to as “SysReset#” by
PCMCIA.) Turns to “High” level with an input of 2.3 volts or higher, and turns PERST# to “High” level AND with a “Power
Good” output. Turns to “Low” level and turns PERST# to “Low” level when the input is lowered to 0.8 volts or less.
PERST#
The pin used to provide a reset signal to a PCI-Express compatible card. The status is determined by each output,
PERST#_IN, CPPE# system status, and EN on/off status. Turns to “High” level and activates the PCI-Express compatible
card only if each output is within the “Power Good” threshold with the card kept inserted and with PERST_IN# turned to
“High” level.
PERST#_DELAY
Delay during which the level at PERST# pin turns from Low to High may be set with a capacitor externally applied. The
delay time is determined by the regulated current (2 μA), the reference voltage (0.7 volts) inside the IC and the capacitance
of the capacitor externally applied. The delay time is specified as “at least 1 ms” in “ExpressCard Standard”. It does not
synchronize with PERST_IN#, and it synchronizes only with a “Power Good” output inside the IC. Turns to “Low” level
when SW is turned OFF.
OC
Turns its output to “Low” level if an overcurrent condition is detected. This open drain output may be pulled up to 3.6 volts
power supply via resistor.
OC-Delay
Delay during which the level at OC pin turns from High to Low may be set with a capacitor externally applied. The delay
time is determined by the regulated current (2 μA), the reference voltage (0.7 volts) inside the IC and the capacitance of the
capacitor externally applied. May be used to control with the OC status fed back to the system. If fed back to EN terminal
of this IC, it may be used to turn OFF the output that is provided when an overcurrent condition is detected.

●About heat loss
In designing heat, operate the apparatus within the following conditions.
(Because the following temperatures are warranted temperature, be sure to take margin, etc. into account.)
1. Ambient temperature Ta shall be not more than 125°C.
2. Chip junction temperature Tj shall be not more than 150°C.
Chip junction temperature Tj can be considered under the following two cases.
①Chip junction temperature Tj is found from IC surface temperature TC under actual application conditions:Tj=TC+θj-c×W
＜Reference value＞

Most of heat loss in BD4153FV occurs at the output switch. The power lost is determined by multiplying the on-resistance
by the square of output current of each switch. As BD4153EFV employs the power PKG, the thermal derating
characteristics significantly depends on the pc board conditions. When designing, care must be taken to the size of a pc
board to be used.

Technical Note
●Note For Use
1.Absolute maximum ratings
For the present product, thoroughgoing quality control is carried out, but in the event that applied voltage, working
temperature range, and other absolute maximum rating are exceeded, the present product may be destroyed. Because
it is unable to identify the short mode, open mode, etc., if any special mode is assumed, which exceeds the absolute
maximum rating, physical safety measures are requested to be taken, such as fuses, etc.
2.GND potential
Bring the GND terminal potential to the minimum potential in any operating condition.
3.Thermal design
Consider allowable loss (Pd) under actual working condition and carry out thermal design with sufficient margin provided.
4.Terminal-to-terminal short-circuit and erroneous mounting
When the present IC is mounted to a printed circuit board, take utmost care to direction of IC and displacement. In the
event that the IC is mounted erroneously, IC may be destroyed. In the event of short-circuit caused by foreign matter that
enters in a clearance between outputs or output and power-GND, the IC may be destroyed.
5.Operation in strong electromagnetic field
The use of the present IC in the strong electromagnetic field may result in maloperation, to which care must be taken.
6.Built-in thermal shutdown protection circuit
The present IC incorporates a thermal shutdown protection circuit (TSD circuit). The working temperature is 175°C
(standard value) and has a -15°C (standard value) hysteresis width. When the IC chip temperature rises and the TSD
circuit operates, the output terminal is brought to the OFF state. The built-in thermal shutdown protection circuit (TSD
circuit) is first and foremost intended for interrupt IC from thermal runaway, and is not intended to protect and warrant the
IC. Consequently, never attempt to continuously use the IC after this circuit is activated or to use the circuit with the
activation of the circuit premised.
7.Capacitor across output and GND
In the event a large capacitor is connected across output and GND, when Vcc and VIN are short-circuited with 0V or GND
for some kind of reasons, current charged in the capacitor flows into the output and may destroy the IC. Use a capacitor
smaller than 1000 μF between output and GND.
8.Inspection by set substrate
In the event a capacitor is connected to a pin with low impedance at the time of inspection with a set substrate, there is a
fear of applying stress to the IC. Therefore, be sure to discharge electricity for every process. As electrostatic
measures, provide grounding in the assembly process, and take utmost care in transportation and storage. Furthermore,
when the set substrate is connected to a jig in the inspection process, be sure to turn OFF power supply to connect the jig
and be sure to turn OFF power supply to remove the jig.
9.IC terminal input
+
The present IC is a monolithic IC and has a P substrate and P isolation between elements.
With this P layer and N layer of each element, PN junction is formed, and when the potential relation is
GND>terminal A>terminal B, PN junction works as a diode, and
terminal B>GND terminal A, PN junction operates as a parasitic transistor.
The parasitic element is inevitably formed because of the IC construction. The operation of the parasitic element gives
rise to mutual interference between circuits and results in malfunction, and eventually, breakdown. Consequently, take
utmost care not to use the IC to operate the parasitic element such as applying voltage lower than GND (P substrate) to
the input terminal.

Technical Note
10. GND wiring pattern
If there are a small signal GND and a high current GND, it is recommended to separate the patterns for the high current
GND and the small signal GND and provide a proper grounding to the reference point of the set not to affect the voltage at
the small signal GND with the change in voltage due to resistance component of pattern wiring and high current. Also for
GND wiring pattern of component externally connected, pay special attention not to cause undesirable change to it.
11. Electrical characteristics
The electrical characteristics in the Specifications may vary depending on ambient temperature, power supply voltage,
circuit(s) externally applied, and/or other conditions. It is therefore requested to carefully check them including transient
characteristics.
12. Capacitors to be applied to the input terminals
The capacitors to be applied to the input terminals (VCC, V3_IN, V3AUX_IN and V15_IN) are used to lower the output
impedance of the power supply to be connected. An increase in the output impedance of the power supply may result in
destabilization of input voltages (VCC, V3_IN, V3AUX_IN and V15_IN). It is recommended to use a low ESR capacitor
with less temperature coefficient (change in capacitance vs. change in temperature), 0.1 μF more or less for VCC and
V3AUX_IN while 1 μF more or less for V3_IN and V15_IN, but it must be thoroughly checked at the temperature and with
the load of the range expected to use because it significantly depends on the characteristics of the input power supply to
be used and the conductor pattern of the pc board.
13. Capacitors to be applied to the output terminals
To the output terminals (V3, V3_AUX, and V15), the output capacitors should be connected between the respective output
terminal and GND. It is recommended to use a low ESR capacitor with less temperature coefficient, 1 μF more or less for
V3 and V15 terminals while 1μF more or less for V3_AUX, but it must be thoroughly checked at the temperature and with
the load of the range expected to use because it significantly depends on the temperature and the load conditions.
14. Not of a radiation-resistant design.
15. .Allowable loss Pd
With respect to the allowable loss, the thermal derating characteristics are shown in the Exhibit, which we hope would be
used as a good-rule-of-thumb. Should the IC be used in such a manner to exceed the allowable loss, reduction of current
capacity due to chip temperature rise, and other degraded properties inherent to the IC would result. You are strongly
urged to use the IC within the allowable loss.
16. In the event that load containing a large inductance component is connected to the output terminal, and generation of
back-EMF at the start-up and when output is turned OFF is assumed, it is requested to insert a protection diode.
OUTPUT PIN
17. Operating ranges
If it is within the operating ranges, certain circuit functions and operations are warranted in the working ambient
temperature range. With respect to characteristic values, it is unable to warrant standard values of electric
characteristics but there are no sudden variations in characteristic values within these ranges.
18. We are certain that examples of applied circuit diagrams are recommendable, but you are requested to thoroughly confirm
the characteristics before using the IC.In addition, when the IC is used with the external circuit changed, decide the IC with
sufficient margin providedwhile consideration is being given not only to static characteristics but also variations of external
parts and our IC including transient
19. Wiring to the input terminals (V3 IN, V3AUX IN, and V15 IN) and output terminals (V3, V3AUX and V15) of built-in FET
should be carried out with special care. Unnecessarily long and/or thin conductors used in wiring may result in
degradation of characteristics including decrease in output voltage.
20. Heatsink
Heatsink is connected to SUB, which should be short-circuited to GND. Solder the heatsink to a pc board properly, which
offers lower thermal resistance.
