The SLG7NT128V is part of STMicroelectronics’ family of System Basis Chips (SBCs) designed to provide a complete solution for products in the vehicle, industry and consumer sectors. The SLG7NT128V integrated circuit (IC) is a highly integrated power management and analog switch IC that combines several features such as reverse battery protection, low-dropout (LDO) regulators, low offset linear regulators, and over-current/over-temperature protection circuits. This makes it an ideal fit for automotive and industrial use and other applications that require reliable power management combined with protection and user flexibility.

The SLG7NT128V can be divided into three main blocks: the power management block, the control block, and the channel control block. The power management block is responsible for the system’s power management and provides the LDO voltage regulation, over-current and over-temperature protection, and reverse battery protection that is required for many automotive and industrial applications. This block also has level shifting and a low offset linear regulator for supplying low-dropout voltages.

The control block of the SLG7NT128V is responsible for controlling all power management blocks, detecting faults, and controlling the voltage output from block to block. This block controls the main enable function, the charge pump, and the application-specific operating parameters, such as the maximum voltage and current output levels, the desired output pulse duration, and the frequency of output pulses. The control block also contains several dedicated logic functions such as addressing, SPI mode selection, open/closed loop functions, and ramp time control.

The third block is the channel control block, responsible for controlling the switches within the SLG7NT128V and providing protection against over-voltages, over-currents, and over-temperatures. This block contains protection circuitry, isolation circuitry, and circuit functions that allow the user to set up different operating parameters for each of the channels depending on their application. It also provides the user with a wide range of options for configuring the channels, including setting the output voltage, current, and pulse width.

In addition to the blocks described above, STMicroelectronics has designed the SLG7NT128V to provide flexibility and user-adjustable feature set. This allows the user to customize their function according to their specific application requirement. The user can select from a variety of operating parameters on each block and can also customize the ramp time for over-temperature, over-current, and over-voltage protection.

Overall, the SLG7NT128V is an extremely well-rounded IC that provides several features essential for reliable power management in automotive and industrial applications. It provides robust protection against reverse battery, overload, and over-temperature conditions, as well as a wide range of user-adjustable features. Combined with its flexibility, cost-effectiveness, and STMicroelectronics’ impressive long-term reliability, the SLG7NT128V is sure to be an ideal choice for many applications.
