STHV1600L

Overview

The STHV1600L is a monolithic, high-speed ultrasound transmitter featuring 16 independent channels with integrated digital beamforming. It generates 5-level high-voltage pulses up to ±100 V (0 to 200 V peak-to-peak) suitable for exciting multiple transducer channels. Each channel integrates an active RTZ clamp and a T/R switch, supporting ±2 A or ±4 A peak output currents in 3/5-level configurations. The device operates at frequencies up to 30 MHz and includes embedded volatile memory for transmission patterns. Packaged in a 144-pin LFBGA (10x10 mm), it functions within a 0°C to 80°C temperature range.

Feature Summary

• 16-channel architecture with built-in digital beamforming allowing programmable channel delays with 5 ns resolution.
• High-voltage pulse generation up to ±100 V with ±2 A or ±4 A source/sink current capabilities.
• Integrated active real-time zeroing (RTZ) clamp circuit and T/R switch with 9 Ω ON resistance.
• Embedded 64 kbit volatile memory for storing transmission patterns and waveform compression algorithms.

Applications

• Medical ultrasound imaging systems
• Non-destructive testing (NDT) ultrasound transmission equipment
• Pulse waveform generators
• Piezoelectric transducer drivers

Procurement Notes

Verify the specific ordering suffix 'L' against the official STMicroelectronics datasheet DB3667 Rev 2. Confirm that the package type matches the 144-LFBGA specification and that the operating temperature range meets the 0°C to 80°C requirement. Ensure compatibility with the required serial interface clock speeds up to 200 MHz before procurement.

Selection Notes

Select this component for applications requiring high integration of transmit beamforming and high-voltage pulsing. The device supports both pulsed wave (PW) and continuous wave (CW) modes. Consider the embedded low-voltage capacitors which reduce external Bill of Materials. Verify that the system design accommodates the 144-pin LFBGA package dimensions of 10mm x 10mm x 1.4mm.

Part Context

The STHV1600L belongs to the STHV1600 series of specialized power management ICs designed for ultrasound imaging. It utilizes HV SOI technology to ensure latch-up-free operation. The device replaces traditional analog delay lines by implementing digital beamforming directly on the chip, enhancing portability and precision in ultrasound probe designs.
