S-UM5588

Specialized ICS Overview

The S-UM5588 is an octal programmable 5-level high-voltage ultrasound transmit beamformer manufactured by ABLIC Inc. It integrates control logic, waveform memory, delay calculators, gate drive buffers with floating voltage regulators, high-voltage MOSFETs, and active T/R switches. The device supports output voltages from 0 to ±100V and provides ±2A source/sink current for the first two high-voltage pulses. It features a 1.8V to 3.3V LVCMOS logic interface, 100MHz write/50MHz read SPI, and dual-edge 100MHz clock support for 5ns channel-to-channel delay resolution. Packaged in a 68-lead QFN (10x10mm) with an exposed pad.

Specialized ICS Procurement Notes

Verify package configuration matches the 68-QFN (10x10mm) specification. Confirm that the supplier documentation explicitly identifies the component as the S-UM5588 model. Ensure handling procedures account for moisture sensitivity and the requirement to solder the exposed thermal pad to ground for proper operation and thermal management.

Specialized ICS Selection Notes

Select this component when an octal channel configuration with independent programmable delays is required. Verify that the system power supplies can provide the necessary ±100V high-voltage rails and ±5V logic supplies. Ensure the host controller supports the required SPI interface speeds and LVDS or CMOS clock inputs for precise timing control.

Specialized ICS Part Context

This component belongs to ABLIC's specialized IC lineup for ultrasound applications. It functions as a digital transmit beamformer, distinct from simple pulsers by integrating waveform memory and delay calculation capabilities directly on-chip. The device is designed to replace discrete high-voltage switching solutions with a single integrated circuit.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure compatibility with the 68-VFQFN package dimensions and verify that replacement devices support the same ±100V output range and octal channel architecture.

Specialized ICS FAQ

What is the maximum output frequency supported by the S-UM5588?

The device supports an output frequency of up to 20MHz when operating at ±60V output with a 220pF load.

How is the channel-to-channel delay time controlled?

Channel-to-channel delay is controlled via registers with a resolution of 5ns using a dual-edge 100MHz LVDS or LVCMOS clock. The range is 0 to 1.275μs per channel.

What protection features are included in the S-UM5588?

The device includes automatic thermal protection with an indicator, power-up/down reset for fail-safe operation, latch-up free design, and high-voltage clamp diodes between outputs and power rails.
