Microchip MCP14A0452 | Demoboard Digital power kit (PFC) 50W
4.5A MOSFET Driver With Low Threshold Input and Enable
Overview
| Topology | Power Factor Correction |
| Input voltage | 12-26 V |
| Switching frequency | 10-1000 kHz |
| Output 1 | 42 V / 1.3 A |
| IC revision | 5 |
Description
The MCP14A0451/2 devices are high-speed MOSFETdrivers that are capable of providing up to 4.5A of peakcurrent while operating from a single 4.5V to 18Vsupply. There are two output configurations available;inverting (MCP14A0451) and non-inverting(MCP14A0452). These devices feature low shootthroughcurrent, fast rise and fall times, and shortpropagation delays which make them ideal for highswitching frequency applications.The MCP14A0451/2 family of devices offer enhancedcontrol with Enable functionality. The active-highEnable pin can be driven low to drive the output of theMCP14A0451/2 low, regardless of the status of theInput pin. An integrated pull-up resistor allows the userto leave the Enable pin floating for standard operation.These devices are highly latch-up resistant under anycondition within their power and voltage ratings. Theycan accept up to 500 mA of reverse current beingforced back into their outputs without damage or logicupset. All terminals are fully protected againstelectrostatic discharge (ESD) up to 2 kV (HBM) and200V (MM).
Features
- High Peak Output Current: 4.5A (typical)
- Wide Input Supply Voltage Operating Range: 4.5V to 18V

- Latch-Up Protected: Withstands 500 mA Reverse Current
- Space-Saving Packages:
- 8-Lead MSOP
- 8-Lead SOIC
- 8-Lead 2 x 2 DFN
Typical applications
- Switch Mode Power Supplies / Pulse Transformer Drive / Line Drivers
- Motor and Solenoid Drive
