Intrinsically Safe Boost Protection Module A.BPEX

Intrinsically Safe Boost Protection Module A.BPEX

The A.BPEX module is designed to provide an intrinsic safe protection for step-up (boost) DC-DC power supplies, which is commonly used in modern electronic devices. The unit limits the possible voltage supplied by the step-up converter in case of converter malfunction, thus making the design intrinsically safe against faults in the commercial DC-DC converter. There are several variants of the module, which allows the developer to select the appropriate tripping voltage level on the input (4.9 to 25 V) and the output (4.9 to 53 V) of the power supply. The module is produced in a 28.2 × 22.5 × 5 mm dual line SMD package.

Features:

  • Limits the possible voltage supplied bya step-up (boost) DC-DC converter in case of converter malfunction
  • Protects the DC-DC converter’s surrounding circuitry from over-voltage
  • Quad over-voltage (crowbar) protection
  • Separate protection for converter’s input circuitry (Part A)
  • Separate protection for converter’soutputcircuitry (Part B)
  • Input crowbar can trigger outputprotection
  • 0 to 60 V operating voltage range
  • 4.9 to 25 V tripping voltage for Part A*
  • 4.9 to 53 V tripping voltage for Part B*
  • Very low series resistance (max. 20mΩ)
  • Very low self-capacitance (max. 440nF)
  • No voltage increasing circuitry inside the module
  • IEC and ATEX certified component: Zone 1 and Zone 2, Zone 21 and Zone 22
  • Package dimensions (W × L × H): 28.15mm × 22.5mm × 4.9mm
  • RoHS Compliant, Pb free

* Depends on the selected part number
