PMIC (Power Management Integrated Circuit) is an advanced technology used to regulate the power and manage the power supply needs for a device. PMICs are integrated circuits that provide an interface between the device\'s power source and the device\'s circuitry. The LM5113SDE/NOPB is a Gate Driver from Texas Instruments, it can drive high side, low side, and both high and low side N-channel MOSFETs or IGBTs in power conversion applications. This integrated circuit is ideal for use in high-reliability, high-power designs with small, efficient footprints.

The LM5113SDE/NOPB is a fully integrated, low-voltage Gate Driver IC designed to drive high, low and both high and low-side MOSFETS and IGBTs in power conversion applications. It has over-current and over-temperature protection along with an adjustable dead time. This device also contains an integrated 500nA (typical) current source input to regulate gate drive and these protections are programmable. With its wide 8V to 72V operating voltage range and high switching frequency, it is ideal for use in applications ranging from solar microinverters and AC/DC converters to DC/DC converters, battery chargers and automotive applications.

The LM5113SDE/NOPB is a versatile Gate Driver IC and as such offers several benefits to the user. Its wide 8V to 72V operating voltage range enables it to be used in many different applications, from automotive to solar microinverters, ensuring an efficient design is possible whatever the application. Additionally, the device’s integrated 500nA (typical) current source input helps regulate gate drive for better control and reliability. The wide switching frequency allows for high speed switching with minimized switching losses. Additionally, the device has over-current and over-temperature protection, making it suitable for high reliability applications.

The working principle of the LM5113SDE/NOPB is quite straightforward. The device uses a fast, high side and a slow, low side Driver to turn on and off its respective MOSFET or IGBT. When the output voltage (Vout) of the device is close to the input voltage (Vin), the high side Driver turns on. This turns on the high side MOSFET or IGBT and closes the circuit. When Vout is lower than Vin, the low side Driver turns on, which allows for the current to move from Vout back to Vin, completing the circuit. The device is able to provide a current limit and back EMF protection.

The LM5113SDE/NOPB can be used in a variety of applications such as solar microinverters, AC/DC or DC/DC converters, battery chargers, automotive applications, and general-purpose MOTs and stepper motor control. The device is capable of driving MOSFETs or IGBTs in high, low, and both high and low-side configuration. Additionally, the device is capable of controlling up to 12VPK of current, making it suitable for most automotive and industrial applications. The device is also highly reliable and offers an adjustable dead-time.

In summary, the LM5113SDE/NOPB is a versatile and reliable gate driver IC. With its wide 8V to 72V operating voltage range, integrated current source input, and high switching frequency, the device is suitable for use in high-reliability, high-power designs with small, efficient footprints. The device is capable of driving MOSFETs or IGBTs in high, low, and both high and low-side configurations, with current up to 12VPK.
