NIS5132 Green 3.6A 12V RESETTABLE ELECTRONIC FUSE Description Pin Assignments The NIS5132 is a self-protected resettable electronic fuse designed for consumer applications such as hard disk drives, to industrial ( Top View ) applications to enhance system reliability against catastrophic and shutdown failures. GND 1 Source 10 2 2 To support a wide range of demanding applications, the design has dv/dt 2 9 Source been optimized to operate over the supply range of 9.0V to 18V. For NIS5132MN1 Enable/Fault 3 8 Source robustness and protections, the device integrates a low Rdson NIS5132MN2 I NMOS buffer power device along with an undervoltage lockout, LIMIT 4 7 Source overvoltage clamp, a current limit, a dv/dt control and a thermal NC 5 6 Source 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 U-DFN3030-10 latching type (NIS5132MN1) or auto-retry type (NIS5132MN2).

If an additional delay is required, connect a capacitor from this pin to the ground. Tri-state bi-directional interface pin: The output can be disabled by pulling this pin to ground through an open drain or an open collector. 3 Enable/Fault Additionally, this pin output goes to an intermediate state to indicate that the device is in thermal shutdown state. This pin can also be connected together with other NIS5132 devices to cause a system-wide simultaneous shutdown during thermal events. Current limit setting pin: 4 I LIMIT A resistor between Source pins and this pin sets the overload and short-circuit current limit thresholds. 5 NC No connect The internal NMOS power devices Source pins: 6 to 10 Source These pins are the Source of internal power device and also the output terminal of the electronic fuse Exposed PAD V Positive input voltage to the device DD 2 of 12 NIS5132 May 2016 Diodes Incorporated www.diodes.com Document number: DS36457 Rev. 4 - 2
