S-UM5587P is a 16-channel, 3-level RTZ, high-voltage, high-speed ultrasound pulser. The S-UM5587P comprises logic interfaces, level translators, MOSFET gate drive buffers with floating voltage regulators, high-voltage, high-current MOSFETs, and active T/R switches.

Functions

  • 16channel 3-level pulser with active T/R switch with 2-input per channel

Features

  • 0 to ±100V output voltage
  • ±2A source and sink peak current for pulsing (VPP/VNN)
  • ±1A 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)
  • 10Ω active T/R switch
  • 20MHz output frequency at ±60V output, 220pF load
  • 1.8V to 3.3V CMOS logic interface
  • Noise-cut diodes at each high-voltage output
  • Embedded high-voltage clamp diodes
  • 4-mode output current control
  • Automatic thermal protection with indicator
  • Power-up/down reset function for free power sequencing and for fail-safe in abrupt power drop
  • Latch-up free, low crosstalk between channels by SOI CMOS technology
  • BGA-330(1313)A: 13x13mm BGA package (RoHS compliant)
