HV7360
General Description
The Supertex HV7360 is a high voltage, high-speed, pulse
generator with built-in, fast return to zero damping FETs. This
high voltage and high-speed integrated circuit is designed for
portable medical ultrasound image devices, but can also can
be used for NDT and test equipment applications.
The HV7360 consists of a controller logic interface circuit,
level translators, AC coupled MOSFET gate drivers and high
voltage and high current P-channel and N-channel MOSFETs
as the output stage.
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, it also makes the PCB layout easier.

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
referenced to device ground.

Power-Down Sequence
Note:
Powering up/down in any arbitrary sequence will not cause any
damage to the device. The powering up/down sequence is only
recommended in order to minimize possible inrush current.
