General Description
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 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.
