Introduction

The ISL60002BIB812-TK is a voltage reference commonly used in a variety of applications. It is usually implemented as part of a PMIC (Power Management Integrated Circuit) but can also be used in other applications to make sure that the correct voltage is applied to the required components. This device provides highly stable and accurate output voltages, in particular when compared to more inexpensive and lower quality voltage references. The intent of this article is to explain the application field and working principles of the ISL60002BIB812-TK.

ISL60002BIB812-TK Application Field

The main application field for the ISL60002BIB812-TK is for use as part of a PMIC, however it can also be used for other applications. The device is highly stable and accurate, which makes it well suited to many applications. A few of these applications are as follows:

• Digital Signal Processing (DSP) and Analog Signal Processing (ASP) applications.
• Power Electronics and Power Management applications.
• Portable and Wearable Devices applications.
• High Voltage Protection applications.

The device also has a wide range of operating conditions and performance parameters that suit a variety of applications, including low current drain and low leakages current, as well as low noise and high accuracy.

Working Principle

The working principle of the ISL60002BIB812-TK is relatively simple, even though it provides precise and accurate results. The device is based on a bandgap voltage reference principle, which uses a circuit to create a stable reference voltage. The bandgap reference method uses a circuit to compare two different wires that have opposing temperature coefficients. This voltage reference comes in two different form factors, the Flip Chip (FC) and the Quad Flat No-Lead (QFN).The FC form factor of the device uses a 1.2V bandgap voltage reference with a +/- 10mV accuracy over temperature, and a maximum of 100ppm drift over temperature. The QFN package has a 1.25V bandgap voltage reference with a +/- 20mV accuracy over temperature and a maximum drift of 150ppm over temperature. Both the FC and QFN packages include an internal temperature sensor that compensates for temperature variations and ensures accurate voltage reference outputs of +/- 1%.

Conclusion

In conclusion, the ISL60002BIB812-TK is a voltage reference commonly used in a variety of applications, mainly as part of a PMIC. Its main application field is Digital Signal Processing (DSP) and Analog Signal Processing (ASP) applications, Power Electronics and Power Management applications, Portable and Wearable Devices applications, and High Voltage Protection applications. The device is based on a bandgap voltage reference principle, which uses a circuit to create a stable reference voltage. It is available in two different form factors, the Flip Chip (FC) and the Quad Flat No-Lead (QFN), both of which provide precise and accurate reference voltage outputs.
