NIS5112
Electronic Fuse
The NIS5112 is an integrated switch utilizing a high side N−channel
FET driven by an internal charge pump. This switch features a
SENSEFETt which allows for current sensing using inexpensive
chip resistors instead of expensive, low impedance current shunts.
It is designed to operate in 12 V systems and includes a robust
thermal protection circuit.
Features
• Integrated Power Device
• Power Device Thermally Protected
• No External Current Shunt Required
• Enable/Timer Pin
• Adjustable Slew Rate for Output Voltage
• 9 V to 18 V Input Range
• 30 mW Typical
• Internal Charge Pump
• These are Pb−Free Devices
Typical Applications
• Hard Drives
