MOSFET Driver Delivers 5A for DC/DC converters
upper and lower MOSFET gates from rail-to-rail over a voltage range of 4V to 6.5V and operates from a supply voltage up to 38V. Additionaly the driver can sink up to 5A, source up to 3.2A, and drive multiple MOSFETs in parallel for higher current applications, it also includes an integrated bootstrap schottky diode. The top MOSFET has a rise time of 8ns and a fall time of 7ns and the bottom MOSFET has rise time of 7ns and a fall time of 4ns. Adaptive shoot-through protection is integrated to prevent the upper and lower MOSFETs from conducting simultaneously.The device has a 3-state PWM input for power stage shut-down that is compatible with single and multi-phase controllers, employing a three-state output feature, and has a separate supply for the input logic to match the signal swing of the controller IC and undervoltage lockout circuits on both the driver and logic supplies. The device is offered in a 3mm x 3mm DFN-12 package and operates over a -40°C to 85°C temperature range with prices starting at $1.35 for 1000-piece quantities.
