HV738
General Description
The Supertex HV738 is a four-channel, monolithic, high voltage, high
speed pulse generator. It is designed for portable medical ultrasound
applications. This high voltage and high speed integrated circuit
can also be used for piezoelectric, capacitive or MEMS sensing in
ultrasonic nondestructive detection and sonar ranger applications.
The HV738 consists of a controller logic interface circuit, level
translators, MOSFET gate drivers and high power P-channel and
N-channel MOSFETs as the output stage for each channel.
The output stages of each channel are designed to provide peak
output currents over ±1.1A for pulsing, when in mode 4, with up to
±65 volt swings. When in mode 1, all the output stages drop the
peak current to ±140mA for low-voltage CW mode operation to
decrease the power consumption of the IC. The P and N type of
power FETs gate drivers are supplied by two floating 8.0VDC power
supplies referenced to VPP and VNN. This direct coupling topology
of the gate drivers not only eliminates two high voltage capacitors
per channel, but also makes the PCB layout easier.
