Microchip HV7360 High Speed Ultrasound Pulser
Microchip HV7360 is a high voltage, high-speed, pulse generator with built-in, fast return to zero damping FETs. Microchip HV7360 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.
