AS1923A-BSTT-I

PMIC - Supervisors

The AS1923A-BSTT-I is a type of PMIC (power management IC) supervisor. It is designed to provide power-on reset and watchdog timer functions for microcontrollers and other types of embedded systems. The supervisor includes an integrated voltage detector and a precision timer circuit. It is capable of supporting a wide range of operating voltages and is able to detect supply voltage drops to as low as 1.5V. Additionally, the supervisor has low current consumption, making it suitable for use in applications that require energy efficiency.

Application Fields:

The AS1923A-BSTT-I is used in a wide range of microcontroller-based systems and applications. It is most commonly used in home automation systems, motor control systems, IoT (Internet of Things) devices, and automotive systems. Additionally, it is used in industrial automation systems, power systems, and consumer electronics.

Working Principle:

The AS1923A-BSTT-I works by monitoring the voltage supplied to the system. When the voltage drops below a preset threshold (1.5V), the supervisor will initiate a power-on reset of the system. Additionally, the integrated timer circuit will generate an alert pulse at predetermined time intervals, which can be used to activate the system\'s watchdog timer. The watchdog timer is used to detect when the system has experienced a sudden power loss or a software failure, and will force a system reset if necessary.

The AS1923A-BSTT-I is a low-cost solution that is easy to integrate into existing systems. It is reliable, small in size, and consumes minimal power. These features make it an ideal solution for a variety of applications that require efficient power management.
