L9638D集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

L9638D属于集成电路（IC）的驱动器接收器收发器。由意法半导体集团制造生产的L9638D驱动器，接收器，收发器该系列产品的主要功能是提供必需的硬件资源，以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异，可能包括诸如瞬态抑制之类的功能，这些功能对于通信用途可能并非绝对必要，但对于可能的使用环境却是明智之选。

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
