Description

The Supertex HV7370 is a four-channel, monolithic high voltage, high-speed damper. It is designed for working with the HV738, HV748 or HV758 for medical ultrasound waveform generators requiring fast return-to-zero applications. The HV7370 consists of a controller logic interface circuit, level translators, MOSFET gate drives and high current power Pchannel and N-channel MOSFETs as the output stage for each channel.

The output stages of each channel of HV7370 are designed to provide peak output currents of over ±0.85A for damping to ground,with up to ±100V swing. The control from inputs to outputs uses direct coupling topology, which not only saves components and PCB layout space, but also makes the damping frequency function down to DC.
