As heat pumps have been further improved in efficiency and reliability, they can now be used in a wider range of environmental conditions. As an important market, Littelfuse is also focusing on heat pump applications. In order to help you better understand heat pump applications and market trends, we have specially prepared a presentation for your reference. Here are some of Littelfuse's latest components for the next generation of heat pumps.


01

CoolMOS™ Power MOSFET

  • Using HiPerDyn™ FRED

  • Can be used in buck and boost topologies

  • With electrical isolation back surface

  • 2500V electrical isolation

  • N-channel enhancement mode

  • Low RDSon, High VDSS MOSFET

  • Ultra-low gate charge

02

IXD604 4A Dual Low Side Ultra Fast

MOSFET Drivers

The IXDD604/IXDF604/IXDI604/IXDN604 dual high-speed gate drivers are ideal for driving the latest IXYS MOSFETs and IGBTs. Both outputs can source and sink 4A of current, with voltage rise and fall times of less than 10ns. Each driver input is virtually immune to latch-up, and proprietary circuitry eliminates cross-conduction and current "shoot-through". The IXD_604 series features low propagation delays, as well as fast, matched rise and fall times, making it ideal for high-frequency and high-power applications.


03

TMOV Series Thermally Protected Varistors

The TMOV and iTMOV thermally protected varistors represent the latest advancements in integrated circuit protection technology. Both versions consist of a radial leaded MOV (metal oxide varistor) with an integrated thermally activated element that is designed to disconnect when overheated under conditions such as abnormal overvoltage, limited current, etc. covered in UL 1449. iTMOV varistors differ from TMOV varistors by the introduction of a third lead, which is intended to indicate that the MOV has been disconnected from the circuit. This lead also facilitates connection to a monitoring circuit.

04

USP18967 Series - with copper plated housing

NTC thermistor pipe temperature sensor

Littelfuse offers copper plated clamp-on pipe probe housings for a variety of temperature sensing applications. If the dimensions of this product do not meet your requirements, please feel free to contact us for a more suitable solution.

Features and functions:

  • Tight tolerances

  • Moisture-proof

  • Equipped with the ability to clamp onto 0.875" diameter pipe

    Copper plated clip

  • Maximum operating temperature: 105°C
