Description:INH, EN, WK, bus and pin wake-up, <10 µA sleep current, supports LIN 1.2–2.2A, SAEJ2602, operates on 3.3 V / 5 V, max 20 kbit/s, RoHS & halogen-free, qualified for use until 2037.
Infineon provides a recommended PCB layout in the application note AN2015-11, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The input capacitor selection depends on the input voltage, current, and frequency. A general guideline is to choose a capacitor with a capacitance value between 1-10 μF, a voltage rating above the maximum input voltage, and a low ESR (Equivalent Series Resistance) to minimize voltage ripple and ensure stable operation.
The maximum allowed voltage drop across the internal voltage regulator is typically around 1.5 V to 2 V, depending on the specific application and operating conditions. Exceeding this voltage drop may affect the device's performance and reliability.
The TLE7259-3LE is rated for operation up to 150°C, but it's essential to consider the device's power dissipation, thermal resistance, and cooling mechanisms to ensure reliable operation in high-temperature environments. Consult the datasheet and application notes for specific guidance.
Start by checking the input voltage, current, and temperature to ensure they are within the specified operating ranges. Verify the PCB layout and component selection meet the recommended guidelines. Use oscilloscopes or logic analyzers to monitor the device's signals and identify potential issues. Consult the datasheet, application notes, and Infineon's support resources for further guidance.
