Supertex inc. MD1211 High Speed, Dual MOSFET Driver General Description Features The Supertex MD1211 is a high speed dual MOSFET driver. 10ns average rise and fall time with 1000pF load It is designed to drive high voltage N and P-channel MOSFET 2.0A peak output source/sink current transistors for medical ultrasound and other applications 1.8 to 5.0V input CMOS compatible requiring a high output current for a capacitive load. The high- 4.5 to 13V total supply voltage speed input stage of the MD1211 can operate from 1.8 to Dual matched channels 5.0V logic interface with an optimum operating input signal Reduced clock skew range of 1.8 to 3.3V. The level translator uses a proprietary Low input capacitance circuit, which provides DC coupling together with high-speed Green packaging operation. Applications Medical ultrasound imaging Piezoelectric transducer drivers Non-Destructive Testing (NDT) PIN diode driver High speed level translator Clock/line drivers Typical Application Circuit VDD 0.47F +100V VLL 1.0F OUTA Level 10nF INA Shifter To Piezoelectric 10nF Transducer Level INB -100V Shifter OUTB 1.0F MD1211 Supertex TC6320TG GND Supertex inc. 1235 Bordeaux Drive, Sunnyvale, CA 94089 Tel: 408-222-8888 www.supertex.com MD1211 Ordering Information Pin Configuration Package 8 VLL 1 VDD 8-Lead SOIC (Narrow Body) Device 4.90x3.90mm body 1.75mm height (max) INA 2 7 OUTA 1.27mm pitch MD1211 MD1211LG-G GND 3 6 VDD -G indicates package is RoHS compliant (Green) INB 4 5 OUTB 8-Lead SOIC (LG) (top view) Product Marking Absolute Maximum Ratings YY = Year Sealed YYWW Parameter Value WW = Week Sealed M1211 L = Lot Number Logic supply voltage -0.5V to +5.5V LLLL = Green Packaging Main supply voltage -0.5V to +13.5V Package may or may not include the following marks: Si or Logic input levels -0.5V to V +0.5V LL 8-Lead SOIC (LG) Maximum junction temperature +125C Storage temperature -65C to +150C Operating temperature -20C to +85C Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability.
