ESD PMMA in Medical Devices: Safety and Protection

In the highly sensitive world of medical technology, material selection can mean the difference between reliable operation and catastrophic failure. Electrostatic Discharge (ESD) Poly(methyl methacrylate) (PMMA) has emerged as a game-changing material for medical device manufacturing, offering unparalleled protection against electrostatic hazards while maintaining the clarity and durability…

Philip puts out the high-performance electrostatic protection diode

Philip electronics corporation has put out the two-way electrostatic protection (ESD) of a series of single wire The diode, in order to prevent the instant pulse voltage under static and 30kV to MP3 player and damage of the cellular telephone. Philip new series PESD5V0S1Bx includes the minimum protection diode PESD5V0S1BL in the industry, have ultramicro static pincers bit function that capsulate and outstanding. This apparatus takes up the minimum mother board space, has offered the design flexibility of maximum to design engineer. The semiconductor is becoming smaller, more intensive and more complicated, especially on the definite apparatus of space, but the overall system is easier to be influenced by static pulse. Philip's new electrostatic protection diode series are directed against the space of mother board and all definite application systems of power consumption, adopt ultramicroly and capsulate, and drain is low to 5nA. The electrostatic protection diode is for causing the high frequency of the signal distortion and terminal application trouble to employ the apparatus but the design because of too much protection devices parasitic capacitance, its electric capacity of apparatus is only 35pF. The semiconductor of Philip protects the manager Rochus Kraehe of product market of diode to represent: " Heavy-duty equipment from portable equipment such as the cellular telephone to LCD TV, until multi-place design and high value electronic product of production in Asia more and more, the electrostatic protection diode is essential. Because of this understanding, Philip has expanded the diode product series of electrostatic protection, so as to ensure to continue meeting our requirements for of Asian customer. " The two-way electrostatic protection diode of Philip can bear the static pulse up to 30kV, up to IEC 61000-4-2 (4 grades) The standard, thus has offered the remarkable electrostatic protection characteristic to user. The new device includes 1.0 x 0.6 x 0.5 mm pin SOD882 surface mounting encapsulated PESD5V0S1BL, PESD5V0S1BB that SOD323 encapsulated PESD5V0S1BA and SOD523 capsulated. Stock Philip's new electrostatic protection diode series have already gone into operation. www.philips.com

It accords with LIN2.0 standard and up to the protective physical interface device (Fig.) of 17kV static that the instrument of Dezhou introduces

A few days ago, Dezhou instrument claimed to be employed and put out an independent interconnection network of local area (LIN) to the car The transceiver, can realize that reach 17kV (international electronic technical committee) high And 12kV (dummy) Electrostatic protection (ESD) . This device already can offer for LIN bus line again through the transient test of ISO7637- error protection of 40V to 40V, this makes it get off the ideal choice of the network in the low speed car as severe environment. But TPIC1021 use with the intersection of group and the intersection of microcontroller and system in resistance-capacitance oscillator in conjunction, this realize the intersection of group and of new generation the intersection of car body and application in LIN, such as door module, window regulator of the window, seat control, intelligence sensor and intellectual drive mechanism,etc.. (More details, please see: www.ti.com/sc04220. )

TPIC1021 accords with LIN physical layer norm 2.0 revised edition, and car engineer's association (SAE) J2602 operational procedure suggestion put forward to LIN. The electrostatic protection of this device is up to 17kV (IEC) And 12kV (HBM) ,It is more than twice of the similar device, this reduces demand for the external protection assemble. TPIC1021 accords with LIN 2.0 specified data rate, up to every second 20.0 kBit, and behave on the low data rate that SAE J2602 proposes well too. Low power consumption ( Sleep) The mode can reduce current consumption and electromagnetic radiation to the greatest extent (EME) . TPIC1021 can control LIN bus line to press pendulum rate according to LIN 2.0 standard. In order to offer the electromagnetic antijamming capability of maximum (EMI) ,Radio frequency (RF) caused on the input filter reducible LIN bus of the transceiver Interference. More key characteristics " Main timing function (time-out) on TxD pin ; " Waking up (wake-up) on RxD pin Request; " Can wake up, input into, from the intersection of LIN and bus line (external switch) Or host computer microcontroller unit (MCU) Wake up; " Link with MCU through 5V or 3.3V I/O pin, perfect with TI microcontroller to cooperate; " Supplied power by Vsup (the vehicle carried battery) ,So LIN transceiver does not need outside Vcc again; " Low resistance INH switch control system stabilizator, can make TPIC1021 realize waking from LIN bus line or external switch up, but the other parts of the system are still in the standby mode; " Low electromagnetic radiation (EME) ,Electromagnetic disturbance ability of highly resistance (EMI) ; " Accord with ISO 7637 standard, the transient voltage that can bear the car environment is destroyed. Stock situation and pricing TPIC1021D has already begun to supply, can authorize the retail trader to order in batches through TI and at present, TPIC1021D adopts eight pins small-scaly (S08) Capsulation. When the batch is a thousand, propose the unit price of the retail is 0.55 dollars. TI has product series various in style, not merely can strengthen the characteristic, safety and comfortableness of the car, can also reduce the impact on environment at the same time. The products of TI include overall and integrated LIN subsystem and independent TPIC1021 device.
