HV7361GA-G

The HV7360/HV7361 are high-voltage and high-speed pulse generators with built-in, fast return-to-zero damping Field-Effect Transistors (FETs). An added feature to HV7361 is an integrated two-terminal low-noise T/R switch. These integrated circuits are designed not only for portable medical ultrasound image devices but also for NDT and test equipment applications. Both the HV7360/HV7361 are composed of controller logic interface circuits, level translators and AC-coupled Metal Oxide Semiconductor Field-Effect Transistor (MOSFET) gate drivers. They also have high-voltage and high-current P-channel and N-channel MOSFETs as output stages. 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 but also makes the PCB layout easier.
