Dual Input, High Speed, Dual Channel Power MOSFET Driver

The EL7242/EL7252 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 EL7242/EL7252 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 2-channels.
