AMIS-30600 LIN Transceiver General Description http://onsemi.com PIN ASSIGNMENT RxD 1 8 EN 2 7 VBB 6 LIN 5 GND VCC TxD 3 AMIS− 30600 The single−wire transceiver AMIS−30600 is a monolithic integrated circuit in a SOIC−8 package. It works as an interface between the protocol controller and the physical bus. The AMIS−30600 is especially suitable to drive the bus line in LIN systems in automotive and industrial applications. Further it can be used in standard ISO9141 systems. In order to reduce the current consumption the AMIS−30600 offers a stand−by mode. A wake−up caused by a message on the bus pulls the INH−output high until the device is switched to normal operation mode. The transceiver is implemented in I2T100 technology enabling both high−voltage analog circuitry and digital functionality to co−exist on the same chip. The AMIS−30600 provides an ultra−safe solution to today’s automotive in−vehicle networking (IVN) requirements by providing unlimited short circuit protection in the event of a fault condition. 4 INH Features • LIN−Bus Transceiver ♦ • • • • • • LIN compliant to specification rev. 1.3 and rev. 2.0 ♦ I2T high−voltage technology ♦ Bus voltage $ 40 V ♦ Transmission rate up to 20kbaud ♦ SOIC−150−8 package Protection ♦ Thermal shutdown ♦ Indefinite short circuit protection to supply and ground Load dump protection (45 V) Power Saving ♦ Operating voltage = 4.75 to 5.25 V ♦ Power down supply current < 50 mA EMS Compatibility ♦ Integrated filter and hysteresis for receiver EMI Compatibility ♦ Integrated slope control for transmitter ♦ Slope control dependant from Vbat to enable maximum capacitive load These are Pb−Free Devices (Top View) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 9 of this data sheet. *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. © Semiconductor Components Industries, LLC, 2014 December, 2014 − Rev. 9 1 Publication Order Number: AMIS−30600/D AMIS−30600 V CC V BB 3 7 Thermal shutdown 8 State & Wake−up Control INH 30 k W 2 EN 10 k W COMP 1 RxD 6 Filter VCC 40 k W 4 LIN AMIS−30600 Slope Control TxD 5 PC20050113.3 GND Figure 1.

State Diagrams The AMIS−30600 has a slope which depends of the supply Vbat. This implementation guarantees biggest slope−time under all load conditions. The rising slope has to be slower then the external RC−time−constant, otherwise the slope will be terminated by the RC−time−constant and no longer by the internal slope−control. This would affect the symmetry of the bus−signal and would limit the maximum allowed bus−speed. A capacitor of 10 mF at the supply voltage input VB buffers the input voltage. In combination with the required reverse polarity diode this prevents the device from detecting power down conditions in case of negative transients on the supply line. In order to reduce the current consumption, the AMIS−30600 offers a sleep operation mode. This mode is selected by switching the enable input EN low (see Figure 4). An external voltage regulator can be controlled via the INH output in order to minimize the current consumption of the whole application in sleep mode (see Figure 2). A wake−up caused by a message on the communication bus automatically enables the voltage regulator by switching the INH output high (see Figure 3). In case the voltage regulator control input is not connected to the INH output, or the microcontroller is active respectively, the AMIS−30600 can be set in normal operation mode by EN = H (see Figure 3). http://onsemi.com 4 AMIS−30600 Table 4.
