fn7287 rev 1.00 page 1 of 6 august 26, 2004 fn7287 rev 1.00 august 26, 2004 el7412 high speed, four channel power mosfet drivers datasheet the el7412 contains (4) high performance matched drivers. these very high speed driver s 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 ?turbo-driver' circuit that speeds up input stages by tapping the wider voltage swing at the output. improved speed and dr ive 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 reduction in supply currents over bipolar drivers, yet without the delay time problems commonly associated with cmos devices. dynamic switching lo sses are minimized with non- overlapped drive techniques. pinout 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 ? pb-free available 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 el7412 [20-pin so (0.300)] top view note 1: pins 4C7 and 14C17 are electrically connected. manufactured under u.s. patent nos. 5,334,883, #5,331,047 ordering information part number package tape & reel pkg. dwg. # el7412cm 20-pin so (0.300?) - mdp0027 EL7412CM-T13 20-pin so (0.300?) 13? mdp0027 el7412cmz (see note) 20-pin so (0.300?)
