HDL6M06502B

Specialized ICS Overview

The HDL6M06502B is a 16-channel high-voltage analog switch IC from ABLIC Inc., designed for ultrasound imaging applications. It integrates four banks of single-pole, single-throw (SPST) switches controlled by logic inputs. The device operates on a single +5V supply with a 1.8V to 5V CMOS logic interface. Key electrical parameters include an analog signal voltage range of 0V to ±100V and a peak current capability of 2A per channel. The main switch on-resistance is typically 8 Ω, while the ground clamp switch resistance is 20 Ω. The IC features low off-isolation (-52dB at 5MHz) and supports signal frequencies up to 20MHz.

Specialized ICS Procurement Notes

Verify package marking codes against official datasheet specifications to confirm authenticity. Ensure storage conditions remain within 5–35°C and 40–70% relative humidity to maintain moisture-proof integrity. Check for RoHS compliance documentation if required by local regulations. Confirm that the thermal pad is properly soldered to ground during assembly to ensure correct substrate voltage operation.

Specialized ICS Selection Notes

Select this component when designing ultrasound front-ends requiring high-voltage switching without external high-voltage power supplies. The unique pin configuration facilitates PCB trace routing by separating probe-side and AFE-side connections. Ensure the application environment does not exceed the operating junction temperature of +150°C or the absolute maximum analog signal range of ±105V.

Specialized ICS Part Context

This device belongs to ABLIC Inc.'s high-voltage analog switch family, specifically engineered for medical imaging systems. It replaces discrete high-voltage switch solutions by integrating multiple channels and control logic into a single 52-lead QFN package. The design simplifies board layout and reduces component count in multi-probe ultrasound architectures.

Specialized ICS Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing control logic levels and voltage tolerances before considering alternative components.

Specialized ICS FAQ

What is the function of the DS_ASW input?

The DS_ASW input controls the ground clamp switch. When held High, it always disables the 20 Ω ground clamp switch. When Low, the ground clamp switches alternate on/off with the main switches.

Is power supply sequencing required between VDD and VLL?

No power supply sequencing is required. The device can operate even if VLL differs from VDD, though applying VDD voltage to VLL is recommended for single 5V operation.

How is the IC substrate voltage handled?

The IC substrate voltage (V_SUB) is 0V. The thermal pad on the bottom of the package must be soldered to the ground plane to ensure proper operation and thermal management.
