PMIC - Gate Drivers

The MCP14A0451T-E/MS is a high-speed MOSFET driver, designed by Microchip Technology. It consists of two independent, high-side and low-side pre-drivers with line-side output circuitry, housed in a 2-mm × 2-mm MLPQ-10 package. The driver can handle current up to 2 A and features under-voltage lockout, active clamping and symmetric shoot-through protection. This driver is suitable for a wide range of applications and provides fast switching with minimal ringing.

Application Field

The MCP14A0451T-E/MS high-speed MOSFET driver is suitable for operating at a high-side and low-side power switch and load switch. It can be used as a phase-control of an inductive load, DC/DC converter, motor drive, LED light dimming and low power switch used for non-inductive applications. This driver is also applicable for SMPS (switching-mode power supply) application, solar controller, medical equipment, automotive and industrial applications.

Working Principle

The MCP14A0451T-E/MS high-speed MOSFET driver comprises of two independent, high-side and low-side pre-drivers. The high-side driver is an integrated circuit which is capable of driving an N-channel MOSFET. It operates by sinking a current pulse into the gate of the MOSFET, allowing a current to flow between the source and drain. The low-side driver is an integrated circuit which is capable of driving a P-channel MOSFET. It operates by sourcing a current pulse into the gate of the MOSFET, allowing a current to flow between the source and drain.

This driver also features a wide input voltage range from 6 V to 24 V. It is also temperature and load independent. This allows the driver to efficiently handle fast switching and performance for applications in a wide range of temperature and load conditions. Furthermore, this driver support soft start and can start up or turn a load off in less than 10 nanoseconds. It also offers superior transient suppression through its active clamp circuit and symmetric shoot-through protection.

The MCP14A0451T-E/MS is powered by a 3.3 V supply and offers great ESD immunity. Its high speed MOSFET driver is suitable to drive common-mode EMI filters, over-current protection circuits, traffic control systems and electric vehicle charging. Its low output on-resistance and fast switching speed make it suitable for isolated EMI filter designs and high power converter applications.

In sum, the MCP14A0451T-E/MS high-speed MOSFET driver has proven to be an efficient and reliable solution for a wide range of applications. Its high switching speed, low output on-resistance, wide voltage range and superior transient protection features are a few of its standout features. It is also capable of providing great ESD immunity and operation in a wide range of temperature and load conditions.
