Frequently Asked Questions
What is the continuous drain current capacity?
The device can handle a continuous drain current (ID) up to 13.5 A at room temperature (T ≤ 25°C).
How does the TOPFET protect against overload conditions?
It provides both over-temperature and short-circuit load protection, losing power when either threshold is reached. The status of protection is latched until reset by the input.
What is the maximum continuous junction temperature allowed?
The maximum continuous junction temperature (Tj) for normal operation is 150°C.
Is this device compatible with general control logic?
Yes, it operates at a logic level and can be used to derive signals from controlled power MOSFETs using a 5V compatible input voltage (VIS).
What precautions are required when using this product in sensitive systems?
The manual cautions that the products are not designed for use in life support appliances or systems where malfunction could cause personal injury.
