Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground.


Description

The Supertex HV739 is a single channel monolithic 200V 3.0A high-speed pulser. It is designed for NDT and medical ultrasound applications. This high voltage and high-current integrated circuit can also be used for other piezoelectric, capacitive or MEMS sensor in ultrasonic transducer and sonar ranger applications.

HV739 consists of controller logic interface circuit, voltage level translators, MOSFET gate drives and high current power P-channel and N-channel power MOSFETs as the output stage.

The output stage of HV739 is designed to provide output peak currents over 3.3A with up to 200V swing. The P- and Nchannel power FETs gate drivers are supplied by two fl oating 10 to 12VDC power supplies referenced to VPP and VNN. This direct coupling topology of the gate drivers not only saves two high voltage capacitors per channel, but also makes the PCB layout easier.
