PMIC - Gate Drivers have a broad range of applications, and an important component in the field is the LM5109ASD Gate Driver. This driver provides a highly integrated switching solution for controlling n-channel power MOSFETs in a wide variety of applications, including motor drives, DC-DC converters, and load switches.
The LM5109ASD is a highly integrated gate driver that integrates high-side and low-side outputs for full H-bridge configurations. It includes a low-side floating power MOSFET, a high-side reset MOSFET, a 200mA low-side gate driver, a 500mA high-side gate driver, and a versatile control interface. The LM5109ASD supports up to 60V operation and its operating temperature range is -40°C to +125°C.
The LM5109ASD has several features that make it suitable for various applications. First, it is designed with a low offset deadtime that minimizes switching losses and a wide 4.2V to 60V operating range. Second, it features an overvoltage protection that guards against power switch failure caused by unexpected overvoltage conditions. Third, it has a High-side PWM for dynamic current limit control that allows the user to limit the peak current flow in the power switch, protecting it against overload and short-circuit conditions.
In terms of operating principles, the LM5109ASD uses two high- and two low-side NFET gate drivers to switch a full H-bridge MOSFET design. The integrated logic level output pins are designed to control the H-Bridge based on logic level input signals with very minimal response time. The low-side gates are active-low outputs, while the high-side gates are active high. Each of the four channels has an enable line, allowing each of them to be independently enabled or disabled as needed.
The LM5109ASD also features a slew rate control to adjust the rate at which the output voltage is changed. It further provides a latch-off current limit detection, which is an important safety feature that helps avoid damaging gate drivers. The LM5109ASD also includes a background current sensing to facilitate performance monitoring and feedback.
The LM5109ASD Gate Driver is suitable for a wide range of applications, and is ideal for IoT, automotive and industrial applications. It features adjustable current limits, short-circuit protection, overvoltage protection, and a wide operating temperature range. Its applications include motor drives, DC-DC converters, and load switches.
