Infineon TLE8458Gx LIN收发方案
Infineon 公司的TLE8458Gx是集成了低压降电压稳压器LIN-LDO的LIN收发器,适合给MCU供电同时驱动LIN总线,也可像TLE7259-2GE单独使用.典型应用的静态电流只有8uA.LIN收发器兼容LIN 2.1 (20 kBit/s)或 SAE J2602 (10.4 kbit/s), O稳压器5V或3.3V,输出电流可达50mA.本文介绍TLE8458Gx系列主要特性,方框图, 运行模式状态方框图和应用案例.
LIN Transceiver with integrated Low Drop Voltage Regulator LIN-LDO
The TLE8458G and its derivatives TLE8458GV33, TLE8458GU and TLE8458GUV33, 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 TLE8458Gx is pin compatible to stand-alone LIN transceivers like the TLE7259-2GE. 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 uA, while the TLE8458G 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 TLE8458G can be used in all automotive applications.
