The recommended PCB footprint for the SI3443CDV-T1-E3 is a 5-pin SOT23 package with a 1.5mm x 2.5mm body size. A minimum pad size of 0.5mm x 0.5mm is recommended for each pin.
To ensure proper biasing, connect the input pin (VIN) to a stable voltage source between 2.5V and 5.5V. The output pin (VOUT) should be decoupled with a 1uF ceramic capacitor to ground. Additionally, ensure the input and output capacitors are placed close to the device to minimize parasitic inductance.
The SI3443CDV-T1-E3 is rated for operation from -40°C to 125°C. However, it's recommended to derate the output current by 50% when operating above 85°C to ensure reliable operation.
Yes, the SI3443CDV-T1-E3 is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, it's essential to follow the recommended operating conditions and derating guidelines to ensure reliable operation.
To troubleshoot issues, start by verifying the input voltage and output voltage levels. Check for proper decoupling, correct pin connections, and ensure the device is operated within the recommended temperature range. If issues persist, consult the datasheet or contact Vishay Intertechnologies' technical support for further assistance.
