HV7360/HV7361
Features
• High-Density Integration AC-coupled Pulser
• 0V to ±100V Output Voltage
• ±2.5A Source and Sink Minimum Pulse Current
• Up to 35 MHz Operating Frequency
• 2 ns Matched Delay Times
• 2.5V, 3.3V or 5V CMOS Logic Interface
• Built-in Two-terminal Low-noise Interface for
HV7361
• Low Power Consumption and No Floating Power
Supply Rails or Decoupling Capacitors
Applications
• Medical Ultrasound Imaging
• Piezoelectric Transducer Drivers
• Ultrasound Industrial NDT
• Pulse Waveform Generator
General Description
The HV7360/HV7361 are high-voltage and high-speed
pulse generators with built-in, fast return-to-zero
damping Field-Effect Transistors (FETs). An added
feature to HV7361 is an integrated two-terminal
low-noise T/R switch. These integrated circuits are
designed not only for portable medical ultrasound
image devices but also for NDT and test equipment
applications.
Both the HV7360/HV7361 are composed of controller
logic interface circuits, level translators and
AC-coupled Metal Oxide Semiconductor Field-Effect
Transistor (MOSFET) gate drivers. They also have
high-voltage and high-current P-channel and
N-channel MOSFETs as output stages.
The peak output currents of each channel are
guaranteed to be over ±2.5A with up to ±100V of pulse
swing. The AC coupling topology for the gate drivers
not only saves two floating voltage supplies but also
makes the PCB layout easier.
