Overview
The NIS5132MN3TXG is a cost-effective, resettable electronic fuse produced by onsemi. This device is designed to enhance the reliability of circuits, particularly in applications such as hard drives and motherboard power management. It protects sensitive circuits from excessive input voltage and includes features like an internal overvoltage clamp circuit, which limits the output voltage during transients without shutting down the unit. This allows the load circuit to continue operation even during transient events.

Q & A
- What is the primary function of the NIS5132MN3TXG?
The NIS5132MN3TXG is a resettable electronic fuse designed to protect circuits from excessive input voltage and enhance reliability in applications such as hard drives and motherboard power management.
- What is the input voltage range of the NIS5132MN3TXG?
The input voltage range is from 9 V to 18 V.
- What are the thermal options available for the NIS5132 series?
The NIS5132 series offers both latching and auto-retry thermal options. The MN3 version is a latching version without the overvoltage clamp.
- Does the NIS5132MN3TXG require an external current shunt?
No, the NIS5132MN3TXG does not require an external current shunt.
- What is the typical on resistance of the NIS5132MN3TXG?
The typical on resistance (RDSon) is 44 mΩ.
- What are the ESD ratings for the NIS5132MN3TXG?
The ESD ratings are 2000 V for the Human Body Model (HBM) and 200 V for the Machine Model (MM).
- Is the NIS5132MN3TXG Pb-free and RoHS compliant?
- What is the package type of the NIS5132MN3TXG?
The package type is DFN-10.
- How does the overvoltage clamp circuit function in the NIS5132MN3TXG?
The overvoltage clamp circuit, available in MN1 and MN2 versions, monitors the output voltage and reduces the gate drive of the main FET to limit the output voltage during transients, allowing the load circuit to continue operation. However, the MN3 version does not include this feature.
- What happens during a thermal shutdown in the latching version of the NIS5132MN3TXG?
During a thermal shutdown, the device will shut down and remove power from the load. The output power can be restored by either recycling the input power or toggling the enable pin.
