XC6123E434MR-G

PMIC (power management integrated circuits) are an important component in modern electronic designs, providing a range of regulated voltages and currents, as well as power sequencing and runtime power supply monitoring. Supervisors are a specialized type of PMIC that are used to monitor and control system signals, such as reset signals and power-on-reset signals. The XC6123E434MR-G is a popular supervisor from ON Semiconductor that offers a variety of features and functions, making it suitable for a wide range of applications.

The XC6123E434MR-G is a 3.3V or 5V supervisor with a wide operating voltage range of 2.4V to 5.5V. It features an automatic power-on reset with programmable timeout, reset output delay and manual reset input. It also has an adjustable reset threshold voltage, from 1.2V to 2.3V, and an adjustable active high reset timeout, from 0.3ms to 30 seconds. In addition, the XC6123E434MR-G includes an active high reset output, an active low power good output, and open drain and push-pull outputs. It also has a low quiescent current of only 1.5 µA. This makes it a great choice for low-power systems and battery-powered applications.

The XC6123E434MR-G is primarily used as a watchdog timer and power-on reset generator. It monitors the system voltage level and, if the voltage drops below the reset threshold or the reset timeout period is exceeded, it will generate a reset signal. This prevents system lockups and helps ensure reliable power-up and recovery from sleep/hibernate states. The XC6123E434MR-G also provides an active low power good signal that indicates when the system is up and running. It can be used to signal the start of the system boot-up process or to gate clocks in power management designs.

The XC6123E434MR-G is a great choice for system designs that require reliable supervision and reset signal generation. Its adjustable reset threshold and programmable timeout make it a versatile choice for a variety of application areas, including embedded systems, consumer electronics, test and measurement equipment, automotive systems and industrial systems. It is also well suited for battery-powered designs, due to its low quiescent current.

In summary, the XC6123E434MR-G is a versatile supervision IC that provides reliable reset signal generation and power good indication. Its adjustable threshold and programmable timeout make it suitable for a wide range of applications, including battery-powered designs. It is an ideal choice for system designs that require reliable supervision.
