Introduction to AS1907C18-T

AS1907C18-T is an integrated circuit (IC) from the family of PMIC supervising chips. This device is designed to work in applications where the system boot up and run-time sequencing needs to be monitored. These type of chips are able to detect and reset any fault conditions during low-power system initialization, ensuring correct system initialization and run-time sequencing.

Applications of AS1907C18-T

The AS1907C18-T is specifically designed to work in applications where multiple power domains require sequencing or supervised powerdown. This device is suitable in microprocessor systems, graphics cards, network equipment, and storage controllers. The supervision and power sequencing offered by this device can improve system reliability and maximize battery life. Besides the main application in systems with multiple power domains, the AS1907C18-T is also suitable in applications where timeouts and system reset functions are needed. Its support for multiple reset functions makes it suitable for safety critical applications.

Working Principle of AS1907C18-T

The AS1907C18-T works by monitoring up to five power supplies. During power-up, the device monitors the power supply levels, to assure that the supplies are enabled in sequence, if required. During power-down, the device monitors the power supply levels to assure that the supplies are disabled in the proper order. The AS1907C18-T can work in conjunction with the system\'s microprocessor. The device has an integrated level shifter that is able to interface with and drive the system\'s microprocessor, helping to ensure proper system initialization and sequencing. The device is capable of driving a number of reset signals to the system processor, including Manual Reset (MRST), PLTRST#/RST#, CPU Reset/Clock, Port Reset (PRST) and Watch Dog Timer (WDT). The AS1907C18-T also has a number of functions dedicated to improving system reliability, such as under-voltage lockout, thermal protection, and brown-out detection. In addition, the device provides a number of features for improving system performance, such as multiple voltage management functions and watchdog timer reset.
