Device Overview

Summary

HV7350 is an eight channel monolithic 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. HV7350 consists of a controller logic interface circuit, level translators, MOSFET gate drives, and high current power P-channel and N-channel MOSFETs as the output stage for each channel. The output peak currents of each channel are guaranteed to be over ±1.0A with up to ±60V pulse swings as well as return-to-zero (RTZ) mode. The gate drivers for the output MOSFETs are powered by built-in linear 5.0V regulators referenced to VPP and VNN. This direct coupling topology of the gate drivers not only saves four floating voltage supplies or AC coupling capacitors per channel, but also makes the PCB layout smaller and easier. An input clock pin is available to realign all the logic input control lines to a master clock. Precise logic timing is always essential in any ultrasound systems.
