L9638集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

L9638屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由意法半導(dǎo)體集團制造生產(chǎn)的L9638驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進(jìn)行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

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 (<40?) versus Vs and short circuit protection

■ CMOS compatible TxD, RxD Interface

■ EMI robustness optimised

■ Thermal shutdown and LIN short circuit protection
