MCP1407T-E/MF

MCP1407T-E/MF is a high-side power MOSFET driver manufactured by Microchip Technology. It has a high voltage drive capability and is capable of driving up to +18V gate voltages. This makes it suitable for driving a wide variety of power MOSFETs, IGBTs, and other high-voltage devices, as well as providing diagnostics and gate protection features.

MCP1407T-E/MF is available in two packaging types: a 16-pin SOIC (MCP1407T-E/MF) and a 16-pin TSSOP (MCP1407T-E/MF). The SOIC package is best suited for applications that require a smaller size, whereas the TSSOP package is better for high-density applications. Both packages are electrically similar and have the same operating temperature range. The MCP1407T-E/MF is rated for operation over a temperature range of -40 °C to +125 °C.

MCP1407T-E/MF can be used to drive high-side power stages in a variety of applications. It has two primary modes of operation, High-side N-channel MOSFET Driver and Low-side N-channel MOSFET Driver, each with its own advantages. In the High-side N-channel MOSFET Driver mode, it can drive both N-channel MOSFETs and IGBTs, allowing for faster switching times and allowing the power stage to consume less power. In the Low-side N-channel MOSFET Driver mode, it prevents short-circuits from occurring when power is applied and removed from the load. This prevents damage to the devices and helps increase their reliability.

The MCP1407T-E/MF is a 4-channel device, with two channels for the high-side drive, and two channels for the low-side drive. Each of the high-side drive channels can be individually enabled or disabled, allowing for a wide range of flexibility when setting up the power stages. The low-side drive channels are only enabled when the high-side channels are both enabled. The two channels can also be used together in a push-pull configuration, which allows for even faster switching times and reduced power consumption.

The MCP1407T-E/MF also features built-in drivers to monitor the thermal dissipation of the power devices, allowing for the adjustment of the gate threshold voltage and providing warning when the devices start to overheat. In addition, it provides built-in ESD protection for both the high-side and low-side devices, preventing damage from electrostatic discharge and keeping the devices operating reliably. Finally, it also has a built-in dynamic gate pull-down circuit, which helps keep devices shut off even in the case of a fault.

In conclusion, the MCP1407T-E/MF is a versatile power stage driver that can be used in a wide range of applications. Its wide voltage range and dynamic features make it ideal for driving high-side power stages. It also features built-in protection and monitoring features, ensuring the reliability and longevity of the power devices.
