HV7361GA-G Microchip

HV7360/HV7361 High-Speed 100V 2.5A Two-or-Three-Level Ultrasound Pulsers Features General Description HVCMOS Technology for High Performance HV7360/HV7361 are high-voltage and high-speed pulse generators with built-in fast return-to-zero High Density Integration AC-coupled Pulser damping Field-Effect Transistors (FETs). An added 0V to 100V Output Voltage feature to HV7361 is an integrated two-terminal 2.5A Source and Sink Minimum Pulse Current low-noise T/R switch. These integrated circuits are Up to 35 MHz Operating Frequency designed not only for portable medical ultrasound 2 ns Matched Delay Times image devices but also for NDT and test equipment applications. 2.5V, 3.3V or 5V CMOS Logic Interface Built-in Two-terminal Low-noise Interface for Both HV7360/HV7361 are composed of controller logic HV7361 interface circuits, level translators and AC-coupled Metal Oxide Semiconductor Field-Effect Transistor Low Power Consumption and No Floating Power (MOSFET) gate drivers. They also have high-voltage Supply Rails or Decoupling Capacitors and high-current P-channel and N-channel MOSFETs as output stages. Applications The peak output currents of each channel are Medical Ultrasound Imaging guaranteed to be over 2.5A with up to 100V of pulse Piezoelectric Transducer Drivers swing. The AC coupling topology for the gate drivers Ultrasound Industrial NDT not only saves two floating voltage supplies but also makes the PCB layout easier.
