Microchip HV7360GA-G High-speed â±100v 2.5a two-or-three-level ultrasound pulser Datasheet

HV7360/HV7361
High-Speed ±100V 2.5A Two-or-Three-Level Ultrasound Pulsers
Features
General Description
HVCMOS® Technology for High Performance
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
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.

•
•
•
•
Applications
Both 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.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
