General Description
The Supertex HV748 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 HV748 consists of a controller logic interface circuit, level
translators, MOSFET gate drives 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 ±1.8A for pulsing, when in mode 4, with up
to ±75 volt swings. When in mode 1, all the output stages drop
the peak current to ±400mA 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 9.0VDC
power supplies reference 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.
