Microchip Technology, Inc. PMIC - Power Management - Specialized HV7321K6-G

The HV7321K6-G is a 4-channel, high-voltage ultrasound pulser designed for medical imaging and non-destructive testing applications. It supports output voltages up to ±80V and can deliver a peak output current of ±2.5A. The device features five output levels, including a return-to-zero (RTZ) mode, and integrates transmit/receive (T/R) switches along with output protection and clamp diodes. This pulser operates in both transparent and re-timing modes, with a re-timing clock frequency capability of up to 220 MHz, which helps minimize output jitter when interfacing with field-programmable gate arrays (FPGAs). The HV7321K6-G is compatible with LVCMOS input logic levels of 2.5V and 3.3V, making it suitable for direct interfacing with digital control systems. It is packaged in a compact 9mm x 9mm 64-lead VQFN format, facilitating integration into space-constrained designs.
