LIN BUS TRANSCEIVER
1/14
L9638
October 2004 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 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.
