UDN2981A-T Frequently Asked Questions (FAQ)
-
The maximum current rating of the UDN2981A-T is 1.5A per channel, with a total current limit of 3A for all channels combined.
-
To ensure proper thermal management, it is recommended to provide a heat sink or thermal pad to dissipate heat, and to keep the device away from other heat sources. The maximum junction temperature is 150°C.
-
The minimum input voltage required for the UDN2981A-T is 4.5V, although it is recommended to use a minimum of 5V for optimal performance.
-
Yes, the UDN2981A-T is rated for operation up to 125°C, making it suitable for high-temperature applications. However, it is recommended to derate the current output at higher temperatures to prevent overheating.
-
It is recommended to use a voltage regulator or a voltage clamp to protect the UDN2981A-T from overvoltage conditions. For undervoltage protection, a voltage supervisor or a reset IC can be used to ensure the device is not operated outside of its specified voltage range.
