General Description
The Supertex HV732 is a single, complete, high-voltage,
high-speed, ultrasound transmitter pulser. It is designed for
medical ultrasound imaging applications.
The HV732 consists of a control logic circuit, level translators,
MOSFET gate drive buffers, clamp circuits, and high current,
high voltage MOSFETs as the ultrasound transmitter pulser
output stage. The output stage also has damping transistors
which allows a faster return-to-zero (RTZ) waveform. For
applications that requires the high voltage supplies, V
V
is provided. This keeps the high voltage output transistors off
during the rapid change in supply voltage.
In the output stage there are two pairs of MOSFETs. Each pair
consists of a P-channel and an N-channel MOSFET. They are
designed to have the same impedance, and can provide peak
currents of over ±2.0 amps. The built-in MOSFET gate driver
outputs swing 0 to 12V on PDR and NDR pins. The P-channel
damp output swings 0 to 12V on the DMPO pin.
