Dual Input, High Speed, Dual Channel Power MOSFET Driver Features 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.
