Power management integrated circuits (PMICs) are highly specialized chips designed to convert electric energy and regulate the amount of energy within the device they power. They are an essential component of modern electronics and come in many varieties, such as the STCC02-ED5, which is used in portable electronics, portable medical devices and various industrial applications. This article will discuss the application field and working principle of the STCC02-ED5 PMIC.

Application Field

The STCC02-ED5 is designed to be used in portable electronics and other related industrial applications, such as measurement and control equipment, computer, automotive and telecommunications applications. In particular, it is well-suited to applications where space is at a premium, such as portable medical devices, mobile phones, portable navigation devices and other handheld electronics.

The STCC02-ED5 can be used in both low and high voltage applications, and is capable of delivering up to 8A of current. Its advantages include a variable-focused output voltage between 1.0V and 5.5V and an adjustable current limit. This is made possible by its integrated devices, which include a high-side power switch, a low-side power switch and a high-side/low-side fractional charge pump.

The STCC02-ED5 is also a highly efficient device, offering up to 97% of efficiency for a load current of 2.05 A. Furthermore, it features a low voltage reset circuit and an integrated watchdog timer for added stability.

Working Principle

The STCC02-ED5 is a linear regulator based PMIC. It works by adjusting the output voltage level to meet the required specifications. The device takes in a voltage from an external power source, such as a battery, and it also regulates current that flows through the circuit. This is done by using a voltage reference, an adjustable resistor and a control unit.

When the input voltage falls below the set voltage, the control unit turns on the low-side power switch and switches off the high-side one. This allows the reference voltage to be applied to the adjustable resistor, and the current is regulated accordingly. This process is repeated until the input voltage is raised again and the output voltage is at the desired level.

The STCC02-ED5 PMIC also features protection circuitry that prevents it from being overloaded or shorted. These features make it an ideal choice for portable electronics and related applications. The device is also capable of managing multiple rail voltages, making it well suited for applications with multiple power supplies.

Conclusion

The STCC02-ED5 PMIC is an ideal choice for portable electronics and related industrial applications. It is capable of providing up to 8A of current, with a variable output voltage between 1.0V and 5.5V and adjustable current limit. The device is also highly efficient and offers protection circuitry to prevent it from being overloaded or shorted. The integrated watchdog timer adds stability and makes it an excellent choice for applications with multiple power supplies.
