TPS2149IDGN Frequently Asked Questions (FAQ)
-
The TPS2149IDGN has a maximum current rating of 2A per channel, but it's recommended to limit the current to 1.5A per channel for optimal performance and thermal considerations.
-
To ensure proper thermal management, it's essential to provide a good thermal path from the device to a heat sink or the PCB. Use thermal vias, thermal pads, and a heat sink if necessary. Keep the device away from other heat sources, and ensure good airflow around the device.
-
The recommended input capacitance value for the TPS2149IDGN is 10uF to 22uF, with an ESR (Equivalent Series Resistance) of less than 100mΩ. This helps to filter out noise and ensure stable operation.
-
Yes, the TPS2149IDGN is designed for hot-swapping applications. It has built-in overcurrent protection, undervoltage lockout, and soft-start features that make it suitable for hot-swapping scenarios.
-
The enable pins (EN1 and EN2) are active-high inputs. To enable a channel, drive the corresponding enable pin high (VCC or logic high). To disable a channel, drive the enable pin low (GND or logic low). Make sure to use a pull-down resistor on the enable pins to prevent unwanted enabling.
