Gate driver refers to a power electronic circuit that isolates and provides a high-power signal to control one or more gate driver switches. It is used to drive and control large gate-controlled semiconductor switches such as IGBTs and power MOSFETs. The gate driver can reduce the current consumed on the gate of the power switch and increase the efficiency of the power device, and provides a safe and reliable connection between the controller and the power device.

The MCP1406-E/P is a gate driver for basic gate driving current requirements that is suitable for a wide variety of applications. The MCP1406-E/P features a high current output stage, high current gate drive, wide gate voltage range, and low quiescent current when disabled.

The MCP1406-E/P application field ranges from general DC-DC converter applications to high-power charging applications in battery management systems, industrial automation, power factor correction, power supplies, and industrial motor applications. The MCP1406-E/P is also suitable for general purpose AC-DC converter applications such as lighting control, home appliance, and industrial control applications.

The working principle of the MCP1406-E/P is simple. It has two outputs, each of which is dedicated to driving MOSFETS or IGBTs at low voltage. The two outputs are activated by a single gate driver output at either +V GATE or -V GATE .

When the gate driver output is high, the gate source of the IGBT is connected to +V GATE , the channels of the respected output is enabled, and current is delivered to the gate of the IGBT. When the gate driver output is low, the gate source of the IGBT is connected to -V GATE , the channels of both outputs are disabled and the respective gate of the IGBT is pulled down.

The MCP1406-E/P also features an internal bipolar transistor output stage designed to provide high-current drive capability. The output stage has an integrated current-limit protection feature that limits the maximum current delivered to the gate of the IGBT – protecting it from overcurrent or short-circuit conditions.

The MCP1406-E/P also features a wide gate voltage range that can support both MOSFETs and IGBTs. This feature allows the device to be used in a wide range of applications.

The MCP1406-E/P is also designed to minimize quiescent current when disabled, reducing power consumption and extending the life of the switch. Internal bias regulation and overvoltage protection provide an added layer of protection.

In summary, the MCP1406-E/P is a high current output, high current gate driver suitable for use in a wide range of applications. It features a wide gate voltage range, low quiescent current when disabled, current-limit protection, and overvoltage protection – making it a great choice for applications that require high-power switching solutions.
