Q & A
- What is the primary function of the NIS5021MT2TXG?
The NIS5021MT2TXG is a resettable electronic fuse designed to protect electronic circuits from overcurrent, overvoltage, and thermal failures.
- What are the typical applications of the NIS5021MT2TXG?
Typical applications include hard drives, solid-state drives, servers, motherboards, and fan drives.
- What is the operating temperature range of the NIS5021MT2TXG?
The operating temperature range is from -40°C to 150°C.
- How does the thermal shutdown feature work?
The device shuts down if the die temperature reaches 175°C and can be reset by recycling the input power or toggling the enable pin.
- What is the purpose of the Enable/Fault pin?
The Enable/Fault pin is a tri-state, bidirectional interface used to control the output of the chip and indicate its status, including thermal faults.
- What is the maximum continuous current for the NIS5021MT2TXG on a 4-layer PCB?
The maximum continuous current is 11 A on a 4-layer PCB High-K JEDEC JESD51-7 with >800 mm2, 2 oz. Cu.
- Is the NIS5021MT2TXG ESD protected?
Yes, it has an ESD HBM Rating of 1.5 kV and an ESD CDM Rating of 1.0 kV.
- What is the package type of the NIS5021MT2TXG?
The package type is WDFN10 4x4.
- Is the NIS5021MT2TXG RoHS compliant?
Yes, it is Pb-Free, Halogen Free/BFR Free, and RoHS compliant.
- How does the overvoltage clamp circuit work?
The overvoltage clamp circuit limits the output voltage during transients without shutting down the unit, allowing the load circuit to continue operating.
