MCP1403/4/5 4.5A Dual High-Speed Power MOSFET Drivers Features General Description High Peak Output Current: 4.5A (typ.) The MCP1403/4/5 are a family of dual-inverting, dual- non-inverting, or complimentary output drivers. They Low Shoot-Through/Cross-Conduction Current in can delivery high peak currents of 4.5A typically into Output Stage capacitive loads. These devices also feature low shoot- Wide Input Supply Voltage Operating Range: through current, matched rise/fall times and - 4.5V to 18V propagation delays. High Capacitive Load Drive Capability: The MCP1403/4/5 drivers operate from a 4.5V to 18V - 2200 pF in 15 ns single power supply and can easily charge and - 5600 pF in 34 ns discharge 2200 pF gate capacitance in under 15 ns Short Delay Times: 40 ns (typ.) (typ). They provide low enough impedances in both the Low Supply Current: on and off states to ensure the MOSFETs intended state will not be affected, even by large transients. The - With Logic 1 Input 1.0 mA (typ.) input to the MCP1403/4/5 may be driven directly from - With Logic 0 Input 150 A (typ.) either TTL or CMOS (3V to 18V). Latch-Up Protected: Will Withstand 1.5A Reverse The MCP1403/4/5 dual-output 4.5A driver family is Current offered in both surface-mount and pin-through-hole Logic Input Will Withstand Negative Swing o o packages with a -40 C to +125 C temperature rating. Up To 5V The low thermal resistance of the thermally enhanced Packages: 8-Pin SOIC, PDIP, 8-Pin 6x5 DFN, DFN package allows for greater power dissipation and 16-Pin SOIC capability for driving heavier capacitive or resistive loads. Applications These devices are highly latch-up resistant under any conditions within their power and voltage ratings. They Switch Mode Power Supplies are not subject to damage when up to 5V of noise Pulse Transformer Drive spiking (of either polarity) occurs on the ground pin. All Line Drivers terminals are fully protect against Electrostatic Motor and Solenoid Drive Discharge (ESD) up to 4 kV.
