The LM5111-1MY is a pulse width modulated (PWM) gate driver integrated circuit (IC) that provides high peak current to control power MOSFETs, IGBTs, or other power devices. It is part of Texas Instruments\' Pulse Width Modulation (PWM) Gate Driver family of products. This device provides maximum flexibility as it can be used in either voltage mode or current modes, and has the ability to synchronize its switching frequency to an external reference clock. The LM5111-1MY is ideal for high current, high efficiency applications such as motor control, power switching, AC/DC conversion, and consumer electronics.

The LM5111-1MY is rated for a maximum supply voltage of 20V, with a quiescent current of 20uA (typical), and a an operating range of -40C to 125C. It has an integrated protection circuitry to prevent over temperature, over current and under voltage conditions. It also has a built in over current limiting (OCL) to prevent power device damage. The LM5111-1MY is a single-channel device that supports both PWM and unipolar logic as a signal input. It is also equipped with an input logic range of 0V to 5V, which allows the device to be used with a wide variety of signal sources.

The LM5111-1MY works by receiving a signal input through its input logic range, which is then amplified and inverted to energize the gate of a power device. The power device is then turned on or off based on the signal. The LM5111-1MY has several features that enable it to work more efficiently. For example, it can operate in either voltage or current mode, which gives it the flexibility to be used in a variety of applications. It also has a built-in frequency synchronization circuit to reduce switching noise and improve system efficiency. The device also features an adjustable peak current limit that can be adjusted to better suit the application.

The LM5111-1MY is designed to provide high peak current to safely drive power devices such as power MOSFETs, IGBTs, or other high current switches. It is ideal for high current and high efficiency applications such as motor control, power switching, AC/DC conversion, and consumer electronics.
