NCP5109ADR2G

The NCP5109ADR2G is a high-performance logic-level non-inverting gate driver for very low-side and high-side N-channel power switches. This power module is often used to drive low-voltage and high-voltage loads such as motor drivers, relays, solenoids, and other high-power applications. NCP5109ADR2G is classified as a PMIC (Power Management IC) - Gate Drivers, which makes switching power and managing the energy flow more efficient by providing unidirectional control between a voltage and load.

The NCP5109ADR2G features an advanced N-channel gate driver configuration, making it ideal for gate-controlled power switch applications. It is designed for low-side switch applications and controlling of high-side switches up to 500V. The driver utilizes a built-in under-voltage lockout and internal current limit, making the NCP5109ADR2G a reliable, cost-effective, and high-performance device for applications that require short-circuit protection and/or fault monitoring. It also features an integrated thermal protection feature that disables the device when the internal temperature exceeds a certain threshold.

The NCP5109ADR2G’s advanced gate control structure is designed to provide excellent turn-on and turn-off slew rate control, while reducing the stress on the gate-drive-output (GDO) pin due to minimizing the spike levels. This is accomplished by using an optimized gate-drive current to maintain excellent switching performance. The NCP5109ADR2G also features high levels of ESD protection on all pins, allowing for safer designs and improved reliability.

The NCP5109ADR2G is available in a small 8-pin SOIC package and is optimized for high operating frequencies up to 100 kHz. Additionally, it has a low supply current rating of only 8µA, making it one of the most efficient gate drivers on the market. The IC is designed to ensure high efficiency and superior performance in switching applications.

The NCP5109ADR2G is commonly used for low-side switch applications. It can be used to drive DC-DC converters and power supplies, motor controllers, and light source drivers. It is ideal for controlling high-side switches up to 500V and can be used in applications with high power similar to motor starters, solenoids, relay & signal lights, LED lighting, and many more. Additionally, it is also well-suited for switched capacitor power supplies, point-of-load regulators, and high-efficiency DC loads.

Overall, the NCP5109ADR2G is a high-performance non-inverting gate driver. It provides unidirectional control between voltage and load and provides excellent switching performance with low supply current, ESD protection, and an integrated thermal protection feature. The NCP5109ADR2G is commonly used for low-side switch applications and is ideal for controlling high-side switches up to 500V.
