The TS822AIZ-AP is a precise, low noise, high voltage reference IC designed for use with battery-powered consumer equipment and general-use applications. The device has a precise star-up voltage of 1.237V and wide-input voltage range (1.2V to 3.6V). The TS822AIZ-AP is a low-dropout, low-noise application-specific reference IC that has a built-in voltage-sense amplifier, temperature-stabilization circuit, and digital-level voltage switch. In addition, the IC features low quiescent current (180uA) and power-on reset support.

The TS822AIZ-AP operates in two modes: low current and high current. In the low current mode, the voltage reference is enabled when the voltage dips below the start-up voltage (1.237V). When the voltage exceeds the start-up voltage, the voltage reference is disabled, resulting in a lower quiescent current. In the high current mode, the reference is enabled when the voltage is above the start-up voltage (1.237V) and disabled when the voltage dips below the start-up voltage.

The voltage-sense amplifier connected to the IC monitors the input voltage level and switches the reference to the appropriate state. The IC also features a built-in temperature-stabilization circuit to ensure that the reference voltage is always maintained in the safe operating range. Additionally, the IC has a digital level voltage switch that can be used to switch the reference voltage from a higher to a lower level when the battery voltage drops below a certain threshold.

The TS822AIZ-AP is a precision voltage reference IC used for various PMIC (power management integrated circuit) and digital signal processing applications, such as portable audio players, mobile phones, battery monitoring and digital video recorders (DVRs). It can also be used in battery-powered consumer electronic devices, such as DVD players, digital cameras and digital video camcorders. The highly stable voltage reference of the TS822AIZ-AP enables accurate and reliable operations in these applications.

In summary, the TS822AIZ-AP is an precision voltage reference IC designed for PMIC and digital signal processing applications, such as portable audio players, mobile phones, battery monitoring and digital video recorders. It has a star-up voltage of 1.237V and a wide-input voltage range (1.2V to 3.6V). It also has a built-in voltage-sense amplifier, temperature-stabilization circuit, and digital-level voltage switch. The IC has a low quiescent current (180uA) and power-on reset support, and offers reliable and accurate operations in its various applications.
