USB Switch ICs

SPST Type

(Single Pole Single Throw)

BH6260MWX

No.11103EAT04

●Description

BH6260MWX is SPST x 2ch and Inverter x 2ch analog switches. Analog SW0 and SW1 pass USB 2.0 high-speed signal.

Analog SW2 and SW3 pass UART signal. Moreover, this is guaranteed from 2.9V to 3.7V as for the range of the

power-supply voltage. Enable signals ENB0, ENB1, EN2, and EN3 can control Analog SW0, SW1, SW2, and SW3.

Furthermore, this is able to pass USB 2.0 high-speed signal without distortion, because of Analog SW0 and SW1 are low

capacitance. The electrostatic discharge protection circuit is built-in in all terminals.

●Features

1) 5Ω switches connect inputs to outputs

2) Low Capacity Analog SW 2ch with clamp Diode

3) 1.8V Output Inverter 2ch

4) 16-Pin SON Package (3.3mm x 1.5mm, Height=0.6mm, 0.4mm pitch)

5) It contributes to the miniaturization because all external is built into.

●Applications

Digital Still Cameras, Digital Video Camcorders, Portable Navigation Devices, TV, Portable DVD Players,

Portable Game Systems, Personal computers, PDA, Mobile phones

●Notes for use

(1) Absolute maximum ratings

If applied voltage (VCC1, VCC2), operating temperature range (Topr), or other absolute maximum ratings are

exceeded, there is a risk of damage. Since it is not possible to identify short, open, or other damage modes, if special

modes in which absolute maximum ratings are exceeded are assumed, consider applying fuses or other physical

safety measures.

(2) Recommended operating range

This is the range within which it is possible to obtain roughly the expected characteristics. For electrical

characteristics, it is those that are guaranteed under the conditions for each parameter. Even when these are within

the recommended operating range, voltage and temperature characteristics are indicated.

(3) Reverse connection of power supply connector

There is a risk of damaging the LSI by reverse connection of the power supply connector. For protection from reverse

connection, take measures such as externally placing a diode between the power supply and the power supply pin of

the LSI.

(4) Power supply lines

In the design of the board pattern, make power supply and GND line wiring low impedance. When doing so, although

the digital power supply and analog power supply are the same potential, separate the digital power supply pattern and

analog power supply pattern to deter digital noise from entering the analog power supply due to the common

impedance of the wiring patterns. Similarly take pattern design into account for GND lines as well. Furthermore, for all

power supply pins of the LSI, in conjunction with inserting capacitors between power supply and GND pins, when using

electrolytic capacitors, determine constants upon adequately confirming that capacitance loss occurring at low

temperatures is not a problem for various characteristics of the capacitors used.

(5) GND voltage

Make the potential of a GND pin such that it will be the lowest potential even if operating below that. In addition,

confirm that there are no pins for which the potential becomes less than a GND by actually including transition

phenomena.

(6) Shorts between pins and misinstallation

When installing in the set board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is

installed erroneously, there is a risk of LSI damage. There also is a risk of damage if it is shorted by a foreign

substance getting between pins or between a pin and a power supply or GND.

(7) Operation in strong magnetic fields

Be careful when using the LSI in a strong magnetic field, since it may malfunction.

(8) Inspection in set board

When inspecting the LSI in the set board, since there is a risk of stress to the LSI when capacitors are connected to

low impedance LSI pins, be sure to discharge for each process. Moreover, when getting it on and off of a jig in the

inspection process, always connect it after turning off the power supply, perform the inspection, and remove it after

turning off the power supply. Furthermore, as countermeasures against static electricity, use grounding in the

assembly process and take appropriate care in transport and storage.

(9) Input pins

Parasitic elements inevitably are formed on an LSI structure due to potential relationships. Because parasitic

elements operate, they give rise to interference with circuit operation and may be the cause of malfunctions as well as

damage. Accordingly, take care not to apply a lower voltage than GND to an input pin or use the LSI in other ways

such that parasitic elements operate. Moreover, do not apply a voltage to an input pin when the power supply voltage

is not being applied to the LSI. Furthermore, when the power supply voltage is being applied, make each input pin a

voltage less than the power supply voltage as well as within the guaranteed values of electrical characteristics.

(10) Ground wiring pattern

When there is a small signal GND and a large current GND, it is recommended that you separate the large current

GND pattern and small signal GND pattern and provide single point grounding at the reference point of the set so that

voltage variation due to resistance components of the pattern wiring and large currents do not cause the small signal

GND voltage to change. Take care that the GND wiring pattern of externally attached components also does not

change.

(11) Externally attached capacitors

When using ceramic capacitors for externally attached capacitors, determine constants upon taking into account a

lowering of the rated capacitance due to DC bias and capacitance change due to factors such as temperature.

(12) Thermal design

Perform thermal design in which there are adequate margins by taking into account the permissible dissipation (Pd) in

actual states of use.
