The ABLIC Inc. HDL6V5582 is an eight-channel, high-voltage, high-speed fully-integrated pulser for medical ultrasound imaging applications. The HDL6V5582 consists of logic interface, level translators, MOSFET gate drive buffers with internally-generated floating voltage supplies, and high-voltage, high-current MOSFETs for pulsing and active ground damping for each channel.

Functions

The HDL6V5582 can be used as

  • 8-channel, 3-level pulser with active ground damping with 2-input per channel
  • 4-channel, 5-level pulser with active ground damping with 3-input per channel

Features

  • 0 to ±100V output voltage
  • ±1.8A source and sink peak current for pulsing with output blocking high-voltage (HV) diodes
  • ±0.5A source and sink peak current for active ground damping with output blocking HV diodes
  • 25Ω (±0.5A) active high-voltage clamping without output blocking HV diodes (analog SW type)
  • 500Ω (±0.05A) active ground damping without output blocking HV diodes (analog SW type)
  • Internally-generated floating voltage supplies to the gate drive buffers
  • 3-to-5 decoder with clock/transparent mode control for 5-level operation
  • Up to 20MHz operation frequency (@±60V output, 220pF load)
  • 1.8V to 5V CMOS logic interface
  • 4-mode output drive current control for power saving
  • Thermal protection
  • Latch-up free, less crosstalk between channels (SOI CMOS technology)
  • 52-lead 8mm x 8mm QFN package (RoHS compliant)
