LTC1727EMS8-2.5#PBF

Power Management Integrated Circuits (PMICs) are semiconductor devices that power electronic systems. Designed to manage all of the electrical power supply and distribution needs of a system, PMICs are typically tasked with tasks including voltage regulation, charging and battery management. Supervisors are a type of PMIC that provide system reset and power-on reset signals. The LTC1727EMS8-2.5#PBF, for instance, is a supervisor IC that is suited for notebook, desktop and server applications.

LTC1727EMS8-2.5#PBF Application Field

The LTC1727EMS8-2.5#PBF is a multi-function supervisor IC with superior flexibility for system power sequencing, reset generator, and watchdog timer. These features make it well suited for notebook, desktop, server, and industrial applications. This model is the first low-side version of the supervisor family, providing solutions for customers that need power control and protection at lower cost and complexity.

This IC provides several functional blocks, such as an analog module, a power-sequencing module, a reset generation module, and a watchdog timer module. It also offers several options to configure the functionality of the IC, including power sequence timing, user-defined toggle-pin states, and reset assertion level. In addition, the IC also provides provisions for additional reset sources. The power sequencing module can be used to regulate the order for powering on various subsystems and devices in a safe and reliable way.

LTC1727EMS8-2.5#PBF Working Principle

The LTC1727EMS8-2.5#PBF uses a three-phase power sequencing strategy to regulate the order for powering on various subsystems and devices. It starts with supplying power to the analog module, which is then followed by the power-sequencing module. The analog module then outputs a power-on reset signal to the reset generation module, which then switches on the target system. The user can configure the reset generation module to assert reset at a fixed voltage or power-cycle the reset signal. The watchdog timer module provides a failsafe system reset in case of malfunction.

The LTC1727EMS8-2.5#PBF also provides an analog calibration module that enables the user to monitor and adjust the power-on reset voltage of the reset generator. This feature allows the user to tweak the reset voltage based on system requirements. Moreover, the IC also includes a chip enable pin that allows the system to shift the reset signal to an additional source.

Overall, the LTC1727EMS8-2.5#PBF is a flexible, cost-efficient supervisor IC that provides superior system power sequencing, reset generator and watchdog timer features. It is best suited for notebook, desktop and server applications.
