The ACT8930QJ133-T is an integrated power management and system controller. This device is used to monitor, control and optimize power consumption through the power stages of a system. It has been specifically designed for quad-core and octa-core applications. It has a wide range of features and is suitable for power-constrained applications, like mobile applications and portable/wearable devices.The ACT8930QJ133-T integrates several power control and protection functions in a single package, including; power-on reset (POR), power good reset (PGR), low voltage alert (LVA), over voltage alert (OVA), over temperature alert (OTA), software reset (SWR), and short circuit protection (SCP). It also includes several power-up sequencing functions, such as delayed wake-up, low battery operation and adjustable current limit.The ACT8930QJ133-T is able to control power stages for multiple supply systems. It provides individual monitoring, protection and control features for up to 8 threads (Non-HDMI/DVI digital standards). Each power supply thread can have up to 16 channels, fror a total of 128 channels. The device can receive digital I2C commands through predefined pins, and it supports dual-power operation for improved system reliability.The ACT8930QJ133-T includes an on-chip 32-bit ARM Cortex-M4 processor, allowing the system designer to write and execute software instructions according to their needs. The device provides both software and hardware-based power management schemes. For example, it supports Dynamic Voltage and Frequency Scaling (DVFS) and Static Voltage Scaling (SVS) strategies. The ACT8930QJ133-T is designed to work best in systems with high die temperature requirements. It features low-voltage operation and industry-leading low current consumption. It has also been designed to work best with low-noise switching solutions. The device supports both active-clamp PFC and passive PFC power factor correction techniques, as well as PCMOS soft-start and other power-good reset techniques.In summary, the ACT8930QJ133-T is a power management device with a wide range of features, suitable for power-constrained applications. It integrates multiple power control and protection functions in a single package, supports up to 8 threads and up to 16 channels, and offers both software and hardware-based power management schemes. It is ideal for applications that require both high efficiency and low noise operation.
