The ABLIC Inc. HDL6M05586 is an octal, 5-level RTZ, high-voltage, high-speed ultrasound pulser. The HDL6M05586 comprises logic interfaces, level translators, MOSFET gate drive buffers with floating voltage regulators, high-voltage, high-current MOSFETs, and active T/R switches.


  • Octal 5-level pulser with active T/R switch with 3-input per channel


  • 0 to ±100V output voltage
  • ±1.6A source and sink peak current for the 1st and 2nd high-voltage pulses (VPP1/VNN1,VPP2/VNN2)
  • ±1.6A source and sink peak current for active ground clamp
  • 250Ω (±0.1A) active ground clamp without blocking diode for anti-leakage (Analog SW type)
  • Embedded floating voltage regulators
  • Symmetrical positive and negative pulse waveforms for low 2nd order harmonic distortion
  • Up to 200MHz LVDS/LVCMOS clock (transparent mode available)
  • 12Ω active T/R switch with 2-bit turn-on timing control
  • 20MHz output frequency @±60V output, 220pF load
  • 1.8V to 5V CMOS logic interface
  • Noise-cut diodes at each high-voltage output
  • Embedded high-voltage clamp diodes
  • 4-mode output current control for the 2nd high-voltage rail
  • Automatic thermal protection with indicator
  • Power-up/down reset function for free power sequencing and for fail-safe in abrupt power drop
