The MCP14E3/MCP14E4/MCP14E5 device is A 4.0-A buffer /MOSFET driver family. Double inverting, double non inverting, and complementary outputs are standard logical options. The MCP14E3/MCP14E4/MCP14E5 drivers are capable of operating on a single power supply from 4.5V to 18V, and can easily charge and discharge a 2200 pF gate capacitor in less than 15ns(typical). They provide low impedance in both ON and OFF states to ensure that the intended state of the MOSFETs is not affected, even by large transients.
Package Types
The MCP14E3/ MCP14E4/MCP14E5 input can be driven directly from TTL or CMOS (2.4V to 18V). Additional control over the MCP14E3/MCP14E4/ MCP14E5 output is possible by using separate enable functions. Pins ENB_A and ENB_B are active at a high level and internally pulled up to VDD. The pin may float in the water during standard operation.
The MCP14E3/MCP14E4/MCP14E5 dual-output 4.0-A driver family is available in surface mount and pinhole packaging and is rated for temperatures from -40°C to +125°C. The low thermal resistance of the Thermal Enhanced DFN package allows greater power dissipation capacity to drive heavier capacitive or resistive loads. These devices are highly resistant to latching under any conditions within their power and voltage ratings.
Functional Block Diagram
They are not damaged when noise spikes (of any polarity) of up to 5V occur on the ground pins. They can accept, without damage or logical confusion, that up to 1.5A reverse current is forced back into their output. All terminals are fully protected from electrostatic discharge (ESD) up to 4 kV.
