Octal ±100V 1.8A 3-Level Ultrasound Pulser HDL6V5583

The ABLIC Inc. HDL6V5583 is an octal, high-voltage, high-speed fully-integrated pulser for medical ultrasound imaging applications. The HDL6V5583 consists of logic interface, level translators, MOSFET gate drive buffers with embedded/external-selectable floating voltage regulators, and high-voltage, high-current MOSFETs for pulsing and active ground clamping for each channel. The HDL6V5583 is pin-compatible with HDL6V5582/5583E.
