PMIC (Power Management Integrated Circuit) - Gate Drivers are mainly used in MOSFETs to control very high-voltage positive and negative power switches. Gate Drivers provide necessary gate current to drive power switches and protect the switches from damage due to short circuit. The MCP1405-E/P is a gate driver with integrated protection measures, powerful gate driving capability and very low power consumption for a wide range of applications.

MCP1405-E/P is available in TO-220 and SO-8 packages. It integrates a 30V NMOS and a 30V PMOS power transistor, providing separate gate driving and protection for both the P-channel and N-channel MOSFETs. It can serve as a SPDT switch or as an inverter to drive two power switches. It operates from -40C to +125C and is AEC-Q100 Grade 3 qualified. It features a shutdown functionality that allows low quiescent currents, adjustable deadtime and programmable switching frequency to help systems enter Eco-modes.

The MCP1405-E/P can be used in a variety of applications. These include automotive high-side and low-side switches, high-side/low-side switches used in electric vehicles, brushed and Brushless DC motor control, solar inverter systems, home appliances, power factor correction (PFC) and AC-DC rectifiers. It is also suitable for hand-held and portable devices such as smartphones, tablets and laptop computers, as well as power converters used in the telecommunications and industrial automation sectors.

MCP1405-E/P operates on a simple 5V supply voltage. Its working principle is based on the connected PMOS and NMOS transistors, which are driven by a switching control logic. The logic control signals control the gate source drives and the protection devices. The protection devices are responsible for sensing any overcurrent conditions in the output side of the driver and switching off the gate drive output when the overcurrent conditions occur. The output of the driver is further amplified by the PNP Transistor, resulting in a powerful gate drive. The driver features a high current capability, allowing it to drive highly efficient MOSFETs that require higher gate voltages.

MCP1405-E/P is an efficient and reliable gate driver that offers cost savings and improved performance over traditional discrete gate drivers. It is well suited for a wide range of applications in which high switching frequency and short dead time are required. Its integrated protection measures provide excellent protection against short circuits, resulting in increased reliability. Its low power consumption allows it to be suitable for use in low-power applications such as hand-held and portable devices. With its AEC-Q100 qualification, the MCP1405-E/P is an ideal choice for use in automotive applications.
