DESCRIPTION

· The ABLIC Inc. HDL6V5541 is a four-channel, unconditional five-level, high-voltage, high-speed pulser designed for medical ultrasound imaging applications.

· It includes logic interfaces, level translators, MOSFET gate drive buffers, high-voltage, high-current MOSFETs, and active T/R switches.

· Features a 3-to-6 decoder with user-selectable clock/transparent mode control.

FEATURES

· 0 to ±100V output voltage with ±2.0A source and sink peak current without output blocking high-voltage diodes.

· ±1.4A source and sink peak current with ±0.6A active clamping with output blocking high-voltage diodes.

· ±1.0A source and sink peak current for active ground damping with output blocking high-voltage diodes.

· 500Ω (±50mA) active ground damping without output blocking high-voltage diodes (Analog SW type).

· Mutually symmetrical positive and negative pulse waveforms for low 2nd order distortion.

· 3-to-6 decoder with clock/transparent mode control.

· 10Ω active T/R switch with logic-input/direct-input mode control.

· Up to 20MHz operation frequency (@±60V output, 220pF load).

· 1.8V to 5V CMOS logic interface.

· Noise-cut low-voltage diodes at each output.

· 4-mode output drive current control for power saving.

· Thermal protection.

· Latch-up free, low crosstalk between channels by SOI CMOS technology.

· 64-lead 9x9mm QFN package (RoHS compliant).

APPLICATIONS

· Medical ultrasound imaging systems.
