The AK6921FBB is a power management IC (PMIC) for Supervisors. This PMIC is designed primarily for battery-operated systems and meets the need for a variety of power management applications. It integrates a number of functions required of battery-operated applications.

The AK6921FBB PMIC includes a supervisory circuit, voltage detector, RTC timer, oscillator, SRAM, and other peripheral circuits. The supervisory circuit is a circuit that monitors the voltage level and system operating conditions, and alerts the user (for example, through an interrupt) when a fault is detected. It also performs a reset of the system or the power rail when a fault is detected.

The voltage detector is a circuit that detects an input voltage that is greater than or equal to its detect voltage. This function is used to detect the power-on state or detect the input voltage applied by the user.

The RTC timer is a circuit that uses a quartz crystal as an oscillator to keep track of time. The AK6921FBB includes a 32.768 kHz crystal and provides a 16-bit timer that can be used to generate alarms at specific intervals.

The oscillator circuit is a circuit that periodically issues a clock signal. The clock frequency is determined by the values of the external components connected to the oscillator circuit. The AK6921FBB includes an on-chip oscillator circuit that can generate a clock signal of up to 30MHz.

The SRAM is a non-volatile memory which is used to store data and can retain its values during power-down. The AK6921FBB includes an 8-bit, 1024-byte SRAM.

The AK6921FBB PMIC has a wide range of applications in battery-operated systems. It is specifically designed to be used in systems that require battery management and power monitoring. These systems may include wearables, healthcare devices, consumer electronics, and industrial/automotive systems.

The AK6921FBB PMIC is able to provide a number of features including a supervisory circuit, voltage detector, RTC timer, oscillator, and SRAM. These features enable the and allow the user to monitor the voltage level and detect faults in the system, detect the power-on state, generate alarms at specified intervals, generate a clock signal of up to 30MHz and store data in non-volatile memory even when the power is off. This makes the AK6921FBB an ideal choice for powering battery-operated systems.
