PMIC (Power Management Integrated Circuit) plays an important role in the functioning of Printed Circuit Boards (PCBs). To ensure a system’s stability and reliability, modern PMICs include not only power components, but also supervisors. Among these, XC6123C535MR-G is a unique supervisor that combines Power-On Reset (POR) and Electric Static Protection (ESD). This article will discuss the application field and working principle of XC6123C535MR-G.

XC6123C535MR-Gis packaged in a 8-Leadmini-STP, making it suitable for applications that require small size suchas portable devices, PDAs and Cellular phones. This PMIC supervisk ideal for voltage monitoring and resetting purpose in those kinds of gadget. Triple outputs keep the input voltage or frequency stablewithin a predetermined limit. The outputs that can be adjusted are intended for supervising critical power rails, live insertion and external hard reset signals. In addition, a manual reset inputas well as an adjustable watchdog timer is featured with Watchdog Timeout (WDT) outputs.

In terms of working principle, XC6123C535MR-G is an open drain POR (power-on reset) supervisor with an internal logic circuit used to detect power supply levels. It is designed with the most advanced manufacturing breakdown protection function and live insertion circuit. The adjustable voltage threshold is determined using an externally connected resistor and will provide a Reset Low assertion shortly after power is applied and after the power crosses the threshold. Outputs from the Reset Low pin will deassert when the power level rises above the time-delayed reset voltage.

The ESD (Electric Static Protection) feature of XC6123C535MR-G is also remarkable. It can offer improved protection against electrostatic discharge (ESD) events up to IEC 61000-4-2 Level 4. This helps protect electronic circuits against ESD damage, which would otherwise degrade the device’s performance and produce unexpected results. Every package of the supervisor is subjected to a qualitative ESD test.

As a highly integrated supervisor, XC6123C535MR-G has many powerful features to provide the highest standards of security and protection. Together with its excellent ESD protection feature and adjustable Reset Low threshold, XC6123C535MR-G offers unmatched performance in small size applications that require voltage monitoring and resetting. Its comprehensive feature set also renders it ideal for critical power rails, live insertion and external hard reset signaling.
