Automotive ICs MLX80001 4-Channel LIN Transceiver Intelligent Drivers and Actuators Features Hall ICs The MLX80001 is a 4 channel physical layer device for applications using the Local Interconnect Network (LIN) protocol. The device is designed in accordance to the physical layer definition of the LIN Protocol Specification Package 2.0 and the SAE J2602 standard .The IC furthermore can be used in ISO9141 systems. Because of the very low current consumption of the MLX80001 in the recessive state it’s suitable for ECU applications with hard standby current requirements. An advanced sleep mode capability allows a shutdown of a complete master node. 4 Channel enhanced Master Transceiver • Slew rate selection for 10.4kbps (J2602) and 20kbps (LIN 2.x) for optimized radiated emission behavior BUS ICs • Compatible to LIN 2.x and J2602 • High EMI immunity • Disable of slew rate control for fast programming or test modes • High impedance LIN in case of loss of ground , loss of battery and under voltage condition • LIN terminals proof against short-circuits and transients in the automotive environment Silicon MEMS Protections • LIN short to ground protection • ±5kV ESD protection pin LIN, ±4kV ESD protection on any other high voltage pin Power consumtion CMOS Imaging • Thermal overload protection • Only 20µA typical power consumption in sleep mode • Remote wake up via LIN traffic Bus ICs Other Features • Integrated 1k master termination resistors and decoupling diodes • 5V and 3.3V compatible digital inputs without any external component required • Automotive Temperature Range of –40°C to 125°C • Small MLF 5x5 20pin package • Available as lead-free and ROHS compliant IR Temperature • Control output for voltage regulator Applications VS • LIN Master Nodes with multiple LIN Bus connections • Body Control Module INH Vs 20 Hall ICs WakeFilter TxD4 MODE0 MODE1 GNDD TxD1 VS Rec-Filter RxD1 Receiver 1K LIN1 TSHD MR VCC Driver control 14 MLX80001 13 3 MLPQ5x 5 4 channel2 LIN2 channel3 LIN3 channel4 LIN4 TxD2 TxD3 RxD4 TxD4 12 11 5 channel1 RxD2 RxD3 BUS Ics 15 2 6 Filter TxD1 1 RxD1 LIN1 GNDL Intelligent Drivers and Actuators 200K 16 Charge pump RCO 17 Sleep timer INH RxD3 TxD3 GNDA TxD2 10 RxDx time out Wake-up Control 18 MODE1 Pinout - MLPQ 5x5 20 UV/POR 9 Mode Control Vs monitor/ POR LIN2 RxD2 MODE0 Temp.
