NEW PRODUCT

3.6A 12V RESETTABLE ELECTRONIC FUSE

Description

The NIS5132 is a self-protected resettable electronic fuse designed

for consumer applications such as hard disk drive to industrial

application to enhance system reliability against catastrophic and

shutdown failures.

To support a wide range of demanding applications, the design has

been optimized to operate over the supply range of 9.0V to 18V. For

robustness and protections, the device integrates a low Rdson

NMOS buffer power device along with an under voltage lockout,

overvoltage clamp, a current limit, a dv/dt control and a thermal

shutdown circuits. The overvoltage circuit limits the output voltage

without shutting the device down to allow the load to continue

operating during over voltage. Thermal shutdown can be either

latching type (NIS5132MN1) or auto-retry type (NIS5132MN2).

Features

• 9.0 to 18V operating input voltage

• Integrated NMOS power device with R

DS(ON)

of 30mΩ typical

• Internal current limit - no external current sense resistor in load

path

• Under voltage lockout

• Over voltage clamp (NIS5132MN1 and NIS5132MN2)

• Thermal shutdown

• -40°C to +150°C operating junction temperature

• ESD ratings : HBM ＞ 1500V; MM 200V

• Small low profile U-DFN3030-10 packages

• Lead-Free Finish; RoHS Compliant (Notes 1 & 2)

• Halogen and Antimony Free. “Green” Device (Note 3)

Pin Assignments

Applications

• Hard drives

• Mother board power management

• Printer load power management

Notes: 1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free,

"Green” and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)

and <1000ppm antimony compounds.
