EL7412C High Speed Four Channel Power MOSFET Drivers Features Excellent response times Matched rise and fall times Reduced clock skew Low output impedance Low input capacitance High noise immunity Improved clocking rate Low supply current Wide operating voltage range Applications Full bridge drivers Clock line drivers CCD Drivers Ultra-sound transducer drivers Power MOSFET drivers Switch mode power supplies Class D switching amplifiers Ultrasonic and RF generators Pulsed circuits Ordering Information Part No Temp Range Pkg Outline EL7412CM b40 C to a85 C 20 Lead MDP0027 Thermal SOL General Description The EL7412C contains (4) high performance matched drivers These very high speed drivers are capable of delivering peak currents of 2 0 amps into highly capacitive loads and are ideally suited for ‘‘Full bridge’’ and ultrasound applications The high speed performance is achieved by means of a proprietary ‘‘Tur- bo-Driver’’ circuit that speeds up input stages by tapping the wider voltage swing at the output Improved speed and drive capability are enhanced by matched rise and fall delay times The matched delays maintain the integrity of input-to-output pulse-widths to reduce timing errors and clock skew problems This improved performance is accompanied by a 10 fold reduc- tion in supply currents over bipolar drivers yet without the delay time problems commonly associated with CMOS devices Dynamic switching losses are minimized with non-overlapped drive techniques Connection Diagram 20 Lead Thermal SOL Package Note 1 Pins 4 – 7 and 14 – 17 are electrically connected 7412 – 1 Manufactured under U S Patent Nos 5 334 883 5 331 047 Note All information contained in this data sheet has been carefully checked and is believed to be accurate as of the date of publication however this data sheet cannot be a ‘‘controlled document’’ Current revisions if any to these specifications are maintained at the factory and are available upon your request We recommend checking the revision level before finalization of your design documentation 1994 Elantec Inc 1 page EL7412C High Speed Four Channel Power MOSFET Drivers Typical Performance Curves Contd Average Supply Current vs Voltage and Frequency Average Supply Current vs Capacitive Load Rise Fall Time vs Load 7412 – 11 7412 – 12 Rise Fall Time vs Supply Voltage 7412 – 13 7412 – 14 5 5 Page
