The LM3526M-H/NOPB is a power distribution switch, a type of integrated circuit, that serves the role of controlling power transfer between two circuits, such as a driven and a drive circuit. As part of a power management integrated circuit (PMIC) family of devices, the LM3526M-H/NOPB helps conserve energy, maximize efficiency and speed up the design of smart, energy-saving applications. It also provides key features such as enhanced load and output current regulation and protection, comprehensive voltage monitoring and supervisory functions, and user programmable protection features, allowing for quick and easy system turn-on characteristics.

The LM3526M-H/NOPB features a common source architecture-the source, source enable, and source disable gain the associated power and ground pins of the package. This type of architecture helps reduce the number of parts needed to create a system. The device also incorporates a frequency foldback control circuit and an adjustable dead time control circuit to reduce power dissipation, as well as making it easier to reduce/eliminate unwanted inrush current and ringing on the output side of the part. In addition, the device is designed with a fast single-stage power distribution switch and high-capacity drain current protection.

The functional block diagram of the LM3526M-H/NOPB shows the device’s key components. At the heart of the device is an enable/disable block, which is responsible for providing a logic controlled output enable/disable storage latch. It also features an external voltage supply for the enable/disable control signal. This allows the user to set the appropriate on-off states for the output of the device. The overvoltage and undervoltage protection features are also driven from this block. Additionally, the device features a capacitor monitoring circuit for monitoring capacitor charging time and voltage, as well as an adjustable UV trip level. The device also provides programmable load current regulation and load protection features.

The output of the LM3526M-H/NOPB is provided by two integrated low-side DMOS control translators which also perform logic control of the output on/off. The device provides over-current, under-current, thermal tolerance, and short circuit protection, as well as wide 2:1 load ranges. The output also features an adjustable current limit to provide flexibility in system design. The device also has an adjustable dead time for better load control.

The LM3526M-H/NOPB is an ideal load switch to manage the power needs of motor control, battery management systems, and power supply applications. This device helps streamline the design process by simplifying the power stages and saving board space, while providing key protectional features. It also provides wide 2:1 load ranges and adjustable dead time for better control, as well as enhanced current rating, current limit, and short circuit protection.

The LM3526M-H/NOPB is an excellent choice for use in applications where power supply management is essential. It can be used in a variety of applications such as automotive, consumer, lighting, industrial and medical. The device provides programmable overflow and underflow protection, as well as adjustable load current regulation and load protection features. Its common source architecture helps conserve energy, maximize efficiency and speed up the design of smart, energy-saving applications. Additionally, the LM3526M-H/NOPB features a frequency foldback control circuit and an adjustable dead time control circuit to reduce power dissipation, making it ideal for use in applications where power supply management is essential.
