High-Speed Four Channel MOSFET Driver From Supertex Delivers Sharper Images for 
Medical Ultrasound Applications 
MD1823 Features a Clock Input Pin to Help Realign the Input Control
Pins to a Master Clock Signal, Minimizing Delay Time Errors and Clock
Jitter 
SUNNYVALE, CA -- (Marketwired) -- 11/05/13 --  Supertex (NASDAQ:
SUPX), a recognized leader in high voltage analog and mixed signal
integrated circuits (ICs), today introduced the MD1823, a high-speed
four channel MOSFET driver designed to drive high voltage N- and
P-channel MOSFETs for medical ultrasound imaging applications and
other applications requiring a high output current for a capacitive
load.  
The MD1823 features a clock input pin to help realign the input
control pins to a master clock signal. This will help minimize delay
time errors and clock jitter. A logic input pin, BPS, can be tied
high for users not wanting to use the clock realignment feature (if
BPS = 1, the clock and registers are ignored). Additionally, MD1823
only uses two input pins for the three level RTZ ultrasound pulser
MOSFET gate driver. This feature reduces the FPGA I/O requirement,
which simplifies the PCB layout.  
"The MD1823 MOSFET driver allows for a much improved discrete
ultrasound pulser design," states Jimes Lei, Director of Applications
Engineer for Supertex. "The added clock input will minimize time
delay errors and jitter to achieve a sharper image." 
The MD1823 is available in a lead(Pb)-free/RoHS compliant 16-lead 3x3
QFN package (MD1823K6-G). Samples are available from stock. Lead-time
for production quantities is 4-6 weeks, ARO. Pricing is US$1.17 each
in 1K quantities.
