| EL7242C EL7252C EL7242C EL7252C Dual Input High Speed Dual Channel Power MOSFET Driver Features Logic AND NAND input 3V and 5V Input compatible Clocking speeds up to 10 MHz 20 ns Switching delay time 2A Peak drive Isolated drains Low output impedance Low quiescent current Wide operating voltage 4 5V - 16V General Description The EL7242C EL7252C dual input 2-channel drivers achieve the same excellent switching performance of the EL7212 family while providing added flexibility The 2-input logic and configuration is applicable to numerous power MOSFET drive circuits As with other Elantec drivers the EL7242C EL7252C are excellent for driving large capacitive loads with minimal delay and switching times ``Shoot-thru'' protection and latching circuits can be implemented by simply ``cross-coupling'' the 2channels Connection Diagrams EL7242C Applications Short circuit protected switching Under-voltage shut-down circuits Switch-mode power supplies Motor controls Power MOSFET switching Switching capacitive loads Shoot-thru protection Latching drivers 7242 -
