TLE7529

The TLE7529 is designed as one kind of LIN transceiver that works as an interface between the protocol controller and the physical bus. This device offers a sleep operation mode to reduce the current consumption and in this mode the voltage regulator can be switched off by the TLE7529 to minimize the current consumption of the whole application. And it also offers a very good EMC performance within a broad frequency range independent from battery voltage.

Features of the TLE7529 are:(1)suitable for 12V and 24V boardnet;(2)bus short to GND handling;(3)very low leakage current in unpowered state;(4)overtemperature protection;(5)very low current consumption in sleep mode;(6)support of K-line function;(7)bus short to VBAT protection;(8)control output for voltage regulator;(9)for 3.3 V and 5 V C I/O;(10)wake up source recognition (local/remote);(11)compatible to LIN specification 1.2, 1.3 and 2.0;(12)transmission rate up to 20 kBaud.

The absolute maximum ratings of the TLE7529 can be summarized as:(1)battery supply voltage:-0.3 to 40 V;(2)bus input voltage versus GND:-40 to +40 V;(3)bus input voltage versus Vs:-40 to +40 V;(4)wake input versus GND:-40 to +40 V;(5)wake input versus Vs:-40 to +40 V;(6)logic voltages at EN, TxD, RxD:-0.3 to 5.5 V;(7)junction temperature:-40 to 150 °C;(8)electrostatic discharge voltage Jedec norm:-2 to 2 kV;(9)output current at INH:-150 to 80 mA.
