S-80824CNMC-B8JT2G Integrated Circuits (ICs)

PMIC, the acronym for Power Management Integrated Circuit, is an important and versatile category of integrated circuits designed for managing power in an electronic system or device. As an integral part of today’s computing systems, PMIC’s have been developed to handle several power needs including: voltage regulation, system bus and peripheral power management, standby power, as well as battery charging and fuel gauging. However, in certain applications, other essential functions such as system reset and system, peripheral supply control may need to be addressed. This is where PMIC supervisors such as S-80824CNMC-B8JT2G come in.

S-80824CNMC-B8JT2G is a high-performance power management supervisor IC with various features. It consists of a voltage supervisor, d-pad switch input and a reset output. It is generally used in Smartphone, Tablet, Wearables and Notebook computers. This device acts as a system reset controller and voltage supervision, managing the reset sequence of the system in response to these voltage inputs. It also provides a unique combination of active low/high reset pulse toggle switch, double reset triggers and adjustable reset timeout mechanisms.

Application field

S-80824CNMC-B8JT2G is designed for a variety of applications including those with varying levels of complexity. It is suitable for any device containing processors, microcontrollers, system DRAM or other digital processing or signal conditioning circuits. Especially in high-performance system such as mobile phones and tablet computers, this device can ensure that all system components remain in a known power-on state and also provide critical system initialization and system safety. Additionally, S-80824CNMC-B8JT2G can be used to provide reset signal when high-speed memories need to be initialized or when peripherals need to be reset.

Working principle

The S-80824CNMC-B8JT2G provides a unique combination of voltage supervisors and reset output generation that are distinct from other PMICs. It uses on-chip voltage supervisors to monitor up to three input voltages. The VOL1 and ON pins supply the working voltages of the device, while the OTW pin provides an over-temperature monitoring function. The slew rate of VOL1 and ON pins can be adjusted by an external capacitor to prevent the inrush current and ensure a smoother supply. Whenever the voltage of any input drops below the threshold voltage, an active low reset signal is generated at the RESET pin. Once the external input voltage reaches or exceeds the set threshold, the reset signal is deasserted. The key features of S-80824CNMC-B8JT2G are that it has adjustable reset timeout, active low/high reset pulse toggle switch and double reset triggers. The combination of these functions enables the device to ensure that the system is not startup- after an unexpected power failure, and boosts system reliability.

In conclusion, S-80824CNMC-B8JT2G power management supervisor IC is a versatile and powerful solution, suitable for many applications. Not only can it provide efficient and reliable power manageability but it also provides the essential features of system reset and system, peripheral supply control which are essential in some applications. By the integration of all of the features and the application of advanced circuit design techniques, S-80824CNMC-B8JT2G can help system designers ensure that their products are always in a known power-on state.
