L9638D013TR

LIN总线收发器 LIN BUS TRANSCEIVER

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
