The LM5107SDX is a member of Texas Instruments’ Wide-Input-Voltage, Self-Powered High-Side Gate Driver (HGD) with configurable dead-time protection. It combines the industry’s widest 3.2V to 18V input voltage range and configurable dead-time protection with a low quiescent current of 2mA. It’s designed to drive gate of power field-effect transistors (FETs) and bipolar transistors, and shows versatility for operating motors, pumps, valves, etc. It is part of the wide range of application fields with guaranteed safety.

The LM5107SDX has a push-pull gate driver designed to drive any N-ple FET combination including a single N-FET, N+1 FET, or an N-FET with an anti-parallel diode connected. The push-pull configuration means the FETs will be driven with very high efficiency. This is because the FETs can be switched “hard” with minimal power loss, as opposed to “soft” switching which wastes power as heat due to charging and discharging the power nodes of the FETs.

The high side gate driver is rated for 2A peak current and comes with an adjustable dead time. This allows for an optimized circuit for switching speeds and prevents shoot through causing current spikes on the power devices. The adjustable dead time can also provide added protection against damage from over voltage spikes or load transients.

The LM5107SDX also offers superb protection features. It has an internal foldback current limit circuit which provides protection from failure from over-current conditions. It also has an integrated thermal shutdown circuit which will protect the device from failure due to overheating.

The LM5107SDX also features a low quiescent current of 2mA which ensures it\'s power efficient and cost effective. This allows it to be used in applications which require a long battery life or low power consumption.

The LM5107SDX has a wide input voltage range of 3.2V to 18V which makes it versatile and suitable for many different applications. It\'s ideal for automotive, industrial and consumer applications and does not need any external components other than a standard power supply.

The LM5107SDX HGD has a wide range of working principles which make it easy to use and suitable for many different applications. It uses a high-side gate drive configuration which allows it to drive N-FET or N+1 FET configurations. It also offers configurable dead-time protection, low quiescent current and wide input voltage range making it an ideal choice for powering motors, pumps, valves, etc.

In summary, Texas Instruments’ LM5107SDX HGD offers a wide range of features that make it an ideal choice for a wide range of industrial, automotive and consumer applications. It’s wide input voltage range, configurable dead-time protection, low quiescent current, and push-pull configuration make it very versatile and reliable. It also offers superb protection features such as an internal foldback current limit circuit and integrated thermal shutdown circuit, making it a safe and cost effective choice for powering motors, pumps, valves, etc.
