Introduction

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.

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)
