AUIPS6011STRL Application Field and Working PrinciplePMIC (Power Distribution Switches, Load Drivers) is a group of components and sub-systems used in power-controlled applications. It includes power switches, current limiters, voltage regulators, and other related components. All these components work together to afford a comprehensive power management solution for electrical applications. AUIPS6011STRL is one of the components produced by Texas Instruments and is based on the company’s latest Automotive Digital Power System (ADPS) technology.The AUIPS6011STRL power switch is designed specifically for automotive applications that require high current, heavy-duty load-switching and current limitation. It is suitable for applications such as power steering, electronic power steering (EPS) systems, electric power steering (EPS) systems, electric power windows, and other high voltage loads. It is capable of switching up to 1.5A and can be configured to switch between 0.75V and 60V. It can support a wide range of automotive loads and its current limitation capability makes it an excellent choice for EPS systems.The AUIPS6011STRL is based on the integrated Automotive Digital Power System (ADPS) technology from Texas Instruments. ADPS combines high performance level requirements and configurability, allowing it to be reliably adapted to automotive application needs. Thanks to its advanced technology, the AUIPS6011STRL has lower RDS(on) values and improved EMC performance. This makes it a more reliable and cost-effective choice for automotive applications.The AUIPS6011STRL consists of two distinct parts—a power switch and an internal control block. The power switch is composed of two N-MOS transistors, an I/O buffer, a sense network, and a load driver IC. The MOS transistors have integrated high-side and low-side terminals that enable the switch to switch between 0.75V and60V. The sense network is used to detect the voltage present at the switch node and the I/O buffer provides input/output protection to avoid over-currents. The internal control block is used to control and monitor the power switch. It includes an internal latch IC, an H-bridge driver, and an ESD protection circuit.The AUIPS6011STRL is programmed using the serial peripheral interface (SPI) and is easily addressed by using the standard SPI protocol. It has the ability to be used in a variety of applications and is programmable to be either latch or toggle mode. This allows the switch to be used in different applications such as load-switching or current-limiting devices. It also offers a wide range of fault thresholds and a wide range of load currents, which allows its use as a fault detection and load drive device in automotive applications.Overall, the AUIPS6011STRL power switch is a highly configurable and reliable power switch that can be used in a variety of automotive applications. It is based on TI’s advanced ADPS technology and is suitable for applications where high current and low-voltage switching is required. It features an internal controlblock with an integrated latch IC, H-bridge driver, and ESD protection circuit. It is programmable with SPI and is capable of being used in both latch and toggle mode.
