ICL8069BCSA is a voltage reference for the power management integrated circuit (PMIC). It is a tool used to precise electrical control system. This voltage reference plays a critical role in PMIC that can detect and regulate the currents and voltages reliability.

According to the specifications, ICL8069BCSA has a very low temperature offset, low temperature drift and an ultra-low jitter of up to 10-8 (\\1.eV/$K). Among their specs, the ICL8069BCSA enables a precise 4.096V (\\1.8V) reference voltage and a very high stability over temperature. It offers a guaranteed initial accuracy of ±0.1%, a ±0.01%/°C drift accuracy and a temperature compensation range of -40°C to 125°C.

Its application field mainly includes precision smart current and voltage regulation. This voltage reference is also used in consumer electronics and industrial electronic control applications, such as digital power supplies, cell phone chargers, battery powered devices and automotive power systems.

To further understand the working principle of the ICL8069BCSA voltage reference, let us take a look at the manufacturing process. The process begins with the fabrication of an N-type and P-type integrated circuit (IC) on a semiconductor material, usually Silicon. The N-type IC is configured to act as the reference voltage’s positive side, and the P-type IC is wired to let current flow through it and into ground, therefore creating the regulated negative voltage supply.

The two ICs are then connected to each other and supplied with a voltage-driven current (Vbe) to ensure the correct reference voltage. This connection and the current drove by Vbe form a feedback loop that keeps the reference voltage stable. This efficient regulating mechanism is known as the avalanche regulator. AI finally, the ICL8069BCSA includes a bandgap reference source, a Vbe circuitry and compensation circuitry to optimize the temperature drift.

In summary, the ICL8069BCSA is a voltage reference for PMIC. This voltage reference is used in consumer electronics and industrial electronic control applications. Its working principle includes a Vbe feedback loop and an avalanche regulator. By using the ICL8069BCSA, one can achieve the highest reliability and lowest audible noise for the design.
