High Volume Pressure Sensor

For Disposable Applications

Motorola has developed a low cost, high volume, miniature pressure sensor package

which is ideal as a sub–module component or a disposable unit. The unique concept of

the Chip Pak allows great flexibility in system design while allowing an economic solution

for the designer. This new chip carrier package uses Motorola’s unique sensor die with

its piezoresistive technology, along with the added feature of on–chip, thin–film

temperature compensation and calibration.

NOTE: Motorola is also offering the Chip Pak package in application–specific

configurations, which will have an “SPX” prefix, followed by a four–digit number, unique

to the specific customer.

Features

• Low Cost

• Integrated Temperature Compensation and Calibration

• Ratiometric to Supply Voltage

• Polysulfone Case Material (Medical, Class V Approved)

• Provided in Easy–to–Use Tape and Reel

Application Examples

• Medical Diagnostics

• Infusion Pumps

• Blood Pressure Monitors

• Pressure Catheter Applications

• Patient Monitoring

NOTE: The die and wire bonds are exposed on the front side of the Chip Pak

(pressure is applied to the backside of the device). Front side die and wire protection

must be provided in the customer’s housing. Use caution when handling the devices

during all processes.

Motorola’s MPX2300DT1/MPX2301DT1 Pressure Sen-

sors have been designed for medical usage by combining

the performance of Motorola’s shear stress pressure sensor

design and the use of biomedically approved materials.

Materials with a proven history in medical situations have

been chosen to provide a sensor that can be used with

confidence in applications, such as invasive blood pressure

monitoring. It can be sterilized using ethylene oxide. The

portions of the pressure sensor that are required to be

biomedically approved are the rigid housing and the gel

coating.

The rigid housing is molded from a white, medical grade

polysulfone that has passed extensive biological testing

including: tissue culture test, rabbit implant, hemolysis,

intracutaneous test in rabbits, and system toxicity, USP.

A silicone dielectric gel covers the silicon piezoresistive

sensing element. The gel is a nontoxic, nonallergenic elasto-

mer system which meets all USP XX Biological Testing Class

V requirements. The properties of the gel allow it to transmit

pressure uniformly to the diaphragm surface, while isolating

the internal electrical connections from the corrosive effects

of fluids, such as saline solution. The gel provides electrical

isolation sufficient to withstand defibrillation testing, as speci-

fied in the proposed Association for the Advancement of

Medical Instrumentation (AAMI) Standard for blood pressure

transducers. A biomedically approved opaque filler in the gel

prevents bright operating room lights from affecting the per-

formance of the sensor. The MPX2301DT1 is a reduced gel

option.

Preferred devices are Motorola recommended choices for future use and best overall value.
