Overview
The S-UM6524 is a low charge injection, 32-channel single-pole single-throw (SPST) high-voltage analog switch IC designed for ultrasound imaging applications. It operates on a single +5 V power supply and supports an analog signal range of 0 V to ±100 V with up to ±150 V voltage overshoot tolerance. The device features a 4 Ω switch on-resistance, 2 A peak analog signal current per channel, and handles analog signal frequencies from 10 kHz to 75 MHz. Logic interface options include a user-selectable serial digital interface or bank interface, powered by a 1.8 V to 5 V CMOS logic supply.
Feature Summary
- Supports ±100 V steady-state analog signals with ±150 V overshoot capability
- Features low charge injection of 15 pC for minimal signal distortion
- Provides embedded thermal protection with a flag indicator output
- Offers selectable serial or bank control interfaces for flexible system integration
Applications
- Ultrasound imaging systems
- Medical diagnostic equipment requiring high-voltage signal routing
- High-density multi-channel signal switching arrays
Procurement Notes
Verify the specific package variant against the official datasheet before ordering. Confirm that the design environment meets the specified operating temperature and humidity storage conditions. Ensure proper ESD handling protocols are followed during installation. Cross-reference the pin configuration map with your PCB layout to guarantee correct terminal alignment.
Selection Notes
Select this component when designing systems requiring high-voltage analog switching without external high-voltage power supplies. Evaluate the 4 Ω on-resistance and 75 MHz frequency response against your signal bandwidth requirements. Consider the available serial or bank interface modes based on your microcontroller's I/O constraints and trace routing limitations.
Part Context
This component belongs to ABLIC's high-voltage analog switch family, specifically engineered for medical ultrasound transducer arrays. It integrates 32 independent channels into a compact BGA package, replacing multiple discrete switches. The design focuses on minimizing parasitic capacitance and charge injection to preserve signal integrity in sensitive acoustic detection circuits.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts if considering alternative vendors. Check absolute maximum ratings and pinout definitions carefully before substituting any other high-voltage analog switch IC.
