PMIC - Gate Drivers are power management circuits that control switching devices such as MOSFETs, IGBTs, and BJTs. These ICs can sense a control signal from a microcontroller or other logic circuit and turn on and off the gate of the switch device. The MIC4124YML-TR is a prime example of such a PMIC.

The MIC4124YML-TR is a four-channel gate driver device primarily intended for driving MOSFETs, IGBTs and gate-turnoff thyristors (GTOs) used in industrial motor and solar applications. It is capable of withstanding transient voltages up to 700V, making it suitable for the high-voltage applications of industrial and solar applications.

The device incorporates four N-channel MOSFET and IGBT gate drivers, each driving an independent output for controlling power to loads or loads paralleled together. Withstand voltage of 600V RMS (50 Hz isolation) is offered by a combination of isolation, operational amplifier, and gate drive circuitry. The high drive capability up to 2A gate current and up to 25A Load Current makes it suitable for high power applications, such as solar power systems, industrial motors and HVAC, as well as portable equipment such as white goods, power tools, and elevator systems.

The MIC4124YML-TR has the ability to drive three level outputs, allowing it to be used to control three-phase outputs. The device is also protected against shoot through and dead short conditions, shorted outputs, and over/ under voltage. It also has a diagnostic output (open drain), which can be used to detect over current and over temperature conditions.

The MIC4124YML-TR can be used in either linear mode or pulse frequency modulation (PFM) mode, with the default mode being linear. The linear mode is used for power control features such as soft start and field adjustment, while the PFM mode is used for load control features such as pre-charge and overload trimming. The MIC4124YML-TR also includes slop compensation, ensuring lossless switching and improved efficiency.

The MIC4124YML-TR can operate over the wide temperature range of -40C to +150C, making it suitable for extreme temperature applications. It is also RoHS compliant, making it suitable for environmentally-friendly applications. The device is also available in a 16-pin TSSOP package, with a wide range of pinouts available to suit specific requirements.

The MIC4124YML-TR is a versatile PMIC Gate Driver suitable for a wide range of industrial and solar applications, including high-voltage and high-power applications. Its wide temperature range and range of available pinouts make it suitable for many different applications, and its robust protection features and slop compensation ensure high efficiency operation.
