LDFMPUR Frequently Asked Questions (FAQ)
-
STMicroelectronics recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the LDFMPUR. The input and output tracks should be kept short and away from noise sources. A good decoupling scheme is also essential.
-
The LDFMPUR requires a power-up sequence of VCC, then VDD, and finally EN. The EN pin should be tied to VCC through a resistor. The device should be configured through the I2C interface, following the protocol outlined in the datasheet.
-
The maximum current rating of the LDFMPUR output stages is 100mA per channel. However, the total current drawn from the device should not exceed 500mA to prevent overheating.
-
First, verify that the power-up sequence is correct and the device is properly configured. Check the I2C communication using a logic analyzer or oscilloscope. If issues persist, try resetting the device or checking for short circuits or overheating.
-
The LDFMPUR is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. It is recommended to use a heat sink or thermal management system to keep the device within its operating temperature range.
