Power Management Integrated Circuits (PMICs) – Supervisors

A power management integrated circuit (PMIC) supervisor is a semiconductor circuit designed to supervise power supply and other power rail related functions in a system. Supervisors usually consist of voltage monitors, power-on reset (POR) circuits, system reset generation, and voltage sequencing and tracking.

S-80828CLNB-B6NT2G is an example of a PMIC supervisor. It is an 8-channel power-sequence supervisor circuit designed for applications with multiple power rails. It features adjustable voltage thresholds for reset assertion and deassertion, an external reset input pin, open drain reset output pins, a power-on reset (POR) circuit and seven additional configurable reset pins. It is designed to help ensure system stability during a system power-up and power-down sequence, and it can detect short and open circuits in the power supply rails.

Application Field

The S-80828CLNB-B6NT2G is a popular power management IC (PMIC) supervisor because it provides a high level of functionality and a very economical price. It is suitable for use in a wide range of systems, including consumer electronics, automotive power systems, communications systems, and various industrial control systems.

The S-80828CLNB-B6NT2G provides superior power sequencing and tracking in order to help ensure system stability. It also provides a variety of configurable reset options along with adjustable voltage thresholds, making it suitable for a wide range of applications.

Working Principle

The basic working principle of the S-80828CLNB-B6NT2G is to provide the system with reliable voltage monitoring and power-on reset functionality. The chip contains eight voltage monitors, each of which can be configured to provide reset assertion and deassertion voltages. When the voltage at any of the monitored points rises to the configured threshold voltage, the corresponding reset output pin is asserted, setting the system reset output pins to the logical “low” state.

When the voltage at any monitored point drops below the configured threshold voltage, the corresponding reset output pin is deasserted, setting the system reset output pins to the logical “high” state. The S-80828CLNB-B6NT2G also contains a power-on reset (POR) circuit, which provides an extra level of security for the system by ensuring that the reset output pins are correctly asserted or deasserted at system power-up and -down.

In addition to providing voltage monitoring and reset functionality, the S-80828CLNB-B6NT2G can be configured to provide seven configurable reset outputs for different system functions. These outputs are designed to provide reset signals in response to various system conditions, such as low voltage or over-temperature conditions.
