The MCP14A0451 is an inverting high-speed MOSFET driver capable of sourcing or sinking 4.5A peak current from a 4.5V to 18V supply. It features an active-high enable pin with integrated pull-up, low-voltage threshold input with hysteresis, and latch-up protection against 500mA reverse current. The device supports output rise and fall times of 9.5ns and 9ns respectively into a 2200pF load, with propagation delays of 16ns (tD1) and 19.5ns (tD2). It is available in 8-lead MSOP, 8-lead SOIC, and 8-lead 2x2 WDFN packages with an exposed thermal pad for improved heat dissipation. The operating temperature range is -40°C to +125°C, and all pins are protected against 2kV HBM and 200V MM electrostatic discharge.
The MCP14A0451/2 devices are high-speed MOSFET drivers that are capable of providing up to 4.5A of peak current while operating from a single 4.5V to 18V supply. There are two output configurations available; inverting (MCP14A0451) and non-inverting (MCP14A0452). These devices feature low shoot through current, fast rise and fall times, and short propagation delays which make them ideal for high switching frequency applications. The MCP14A0451/2 family of devices offer enhanced control with Enable functionality. The active-high Enable pin can be driven low to drive the output of the MCP14A0451/2 low, regardless of the status of the Input pin. An integrated pull-up resistor allows the user to leave the Enable pin floating for standard operation. These devices are highly latch-up resistant under any condition within their power and voltage ratings. They can accept up to 500 mA of reverse current being forced back into their outputs without damage or logic upset. All terminals are fully protected against electrostatic discharge (ESD) up to 2 kV (HBM) and 200V (MM).
