DESCRIPTION
●The L9638 is a monolithic integrated circuit for LIN-bus interface function between the protocol handler in the controller and the physical bus in automotive applications. As well as it can be used in standard ISO 9141 systems.
●FEATURES
●■ Single-wire transceiver for LIN-protocol
●■ Transmission rate up to 20 kbaud
●■ Operating power supply voltage range 6V ≤ Vs ≤ 26V (40V for transients)
●■ Low quiescent current in sleep mode (typ.10µA)
●■ Wake-up through LIN-bus, Enable input (from µC CMOS compatible) or Wake-up input (edge driven)
●■ Wide input and output range -24V ≤ VLIN ≤ Vs
●■ Integrated pull/down/up resistors for LIN, TxD, RxD, EN, INH
●■ Inhibit output with low resistance (<40Ω) versus Vs and short circuit protection
●■ CMOS compatible TxD, RxD Interface
●■ EMI robustness optimised
●■ Thermal shutdown and LIN short circuit protection
