TLE8458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

TLE8458屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由英飛凌科技股份公司制造生產(chǎn)的TLE8458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 TLE8458G and TLE8458GV33 integrate a low drop voltage regulator and a LIN transceiver on one monolithic

circuit. The device is suitable to supply microcontrollers and driving a LIN bus at the same time. The TLE8458 is

pin compatible to stand-alone LIN transceivers like the TLE7259-3GE. The combination of a voltage regulator and

a LIN transceiver on one circuit decreases the quiescent current for a typical application to a value of 8 μA, while

the TLE8458 is still able to wake-up off a LIN bus signal or a signal change on the local wake-up input WK.

Compliant to all LIN standards and with a wide operational supply range, the TLE8458 can be used in all

automotive applications.

Based on the Infineon Smart Power Technology SPT?, the TLE8458 provides excellent ESD robustness together

with a very high electro-magnetic immunity (EMI). The TLE8458 reaches a very low level of electro-magnetic

emission (EME) within a broad frequency range. The TLE8458 family and the Infineon SPT? technology are AEC

qualified and tailored to withstand the harsh conditions in the automotive environment.
