ABLIC Inc. Specialized ICs S-UM5587

The S-UM5587 is a 16-channel programmable 3-level high-voltage ultrasound transmit beam-former designed for advanced ultrasound applications. It features an output voltage range of 0 to ¬±100V and can source and sink currents of ¬±2A, with a peak current of ¬±1A for the active ground clamp. The device supports a 20MHz output frequency at ¬±60V with a 220pF load and provides symmetrical pulse waveforms to minimize harmonic distortion. The S-UM5587 includes a comprehensive set of functionalities such as waveform memory, a delay calculator, and a logic interface compatible with 1.8V to 3.3V LVCMOS levels. It offers a common delay time range from 0.2Oºs to 41Oºs and a channel-to-channel delay time range of 0 to 2.55Oºs, with a resolution of 5ns. The device is housed in a RoHS-compliant BGA-330(1313)A package measuring 13x13mm. Additional features include automatic thermal protection, noise-cut diodes at high-voltage outputs, and a power-up/down reset function for safe operation. The S-UM5587 is suitable for applications requiring precise control of high-voltage ultrasound transmission, making it a valuable component for engineers in the field.
