Part # Distributor Manufacturer Product Category Description
TC646B Microchip Technology, Inc. Microchip Technology, Inc. Not Provided coming out of shutdown mode, auto-shutdown mode, or following a transient fault. A logic low applied to VIN, pin 1, causes fan shutdown. The TC646B also features Microchip Technology's proprietary FanSense ™ technology for increasing system reliability. In normal fan operation, a pulse train...
TC646 Microchip Technology, Inc. Microchip Technology, Inc. Not Provided a transient fault. In normal fan operation, a pulse train is present at SENSE, pin 5. The TC646 also features Microchip Technology's proprietary FanSense ™ TM technology for increasing system reliability. A missing-pulse detector monitors this pin during fan operation. A stalled, open...
TC649B Microchip Technology, Inc. Microchip Technology, Inc. Not Provided coming out of shutdown mode, auto-shutdown mode, or following a transient fault. A logic low applied to VIN, pin 1, causes fan shutdown. The TC649B also features Microchip Technology's proprietary FanSense ™ technology for increasing system reliability. In normal fan operation, a pulse train...

  • Surge Filter Recommendations for 4W up to 50W Modules
    This design note describes an electrical schematics that enables GAIA Converter DC/DC module to. be protected against surges generally occuring in railways applications. Surges are short term high transient voltage on the input bus that are mainly generated by lightning. strokes, arcing faults
  • Surge Filter Recommendations for 50W up to 200W Modules
    This design note describes an electrical schematics that enables GAIA Converter DC/DC module to. be protected against surges generally occuring in railways applications. Surges are short term high transient voltage on the input bus that are mainly generated by lightning. strokes, arcing faults
  • Integrating FETs for Power over Ethernet Applications (.pdf)
    . In this white paper we'll take a closer look at the precautions that must be taken when integrating FETs with PoE controllers: FET current carrying requirements, DC current levels, and Protecting Against faults and start-up transient conditions.
  • Digitally Addressable DALI Dimming Ballast App.
    . The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI). Other features include EMI filtering, transient protection and lamp FAULT protection.
  • Considerations for Selecting Littelfuse MOVs and Fuses for Industrial Motor Applications (.pdf)
    in these locations in terms of suitably high energy and surge current values. Similarly, in selecting a load Fuse, it must obviously be of a value that will allow normal operation, including the allowance for certain fault conditions, but at the same time not open for the transient surges that the MOV
  • Code Design for Dependable Systems - Preface
    that can induce transient. errors. Transient errors are a dominant concern in today 's digital systems. Error control. coding is the most efficient and effective way to tolerate these errors, and is expected to. become ever more important in future VLSI systems. The challenge is to choose among many
  • Improved Method for Arc Flash Hazard Analysis
    Conventional arc flash hazard calculators use simple formulae to calculate the flash protection boundary and the incident energy density, but these methods do not represent the effects of the power supply system correctly. A new method is described which models the transient response of a 3-phase
