The ABLIC Inc. HDL6V5582 is an eight-channel, high-voltage, high-speed fully-integrated pulser for medical ultrasound imaging applications. The HDL6V5582 consists of logic interface, level translators, MOSFET gate drive buffers with internally-generated floating voltage supplies, and high-voltage, high-current MOSFETs for pulsing and active ground damping for each channel.
Functions
The HDL6V5582 can be used as
- 8-channel, 3-level pulser with active ground damping with 2-input per channel
- 4-channel, 5-level pulser with active ground damping with 3-input per channel
Features
- 0 to ±100V output voltage
- ±1.8A source and sink peak current for pulsing with output blocking high-voltage (HV) diodes
- ±0.5A source and sink peak current for active ground damping with output blocking HV diodes
- 25Ω (±0.5A) active high-voltage clamping without output blocking HV diodes (analog SW type)
- 500Ω (±0.05A) active ground damping without output blocking HV diodes (analog SW type)
- Internally-generated floating voltage supplies to the gate drive buffers
- 3-to-5 decoder with clock/transparent mode control for 5-level operation
- Up to 20MHz operation frequency (@±60V output, 220pF load)
- 1.8V to 5V CMOS logic interface
- 4-mode output drive current control for power saving
- Thermal protection
