X4325S8I-2.7

The X4325S8I-2.7 is a CMOS-based System Supervisor with an internal slow start and a reset pulse length of 250ms. It is an ultra-low power device that enables a wide range of applications, including mobile, battery-operated and industrial applications. In addition, it is a power management integrated circuit (PMIC) designed to be used as a supervisory circuit, monitoring system supply and resetting the system if necessary.

In general, this PMIC is used to monitor power supply voltages, providing system reset and brown out protection. The device features an integrated 100ms power-on-reset (POR) timer with a reset pulse length of 250ms. It also has a configuration register allowing the user to select the desired reset pulse length, reset active high or low, reset timeout period, and selectable brown-out threshold. With these options, the X4325S8I-2.7 can be tailored to meet the specific needs of any application.

The X4325S8I-2.7 has a wide range of applications due to its low power consumption and flexibility. It can be used in a wide variety of mobile and battery-operated products such as digital cameras and handheld devices, industrial and automotive applications, and microcontroller systems. In addition, its reset timer and brown-out detection features make it suitable for systems with limited power or limited available board space. The device also can be used to protect microcontrollers from accidental resets due to power disturbances.

The X4325S8I-2.7 works by monitoring the voltage on two input pins, VDD and VCC. VDD is the supply voltage for the device’s internal oscillator and other internal circuitry, while VCC is the supply voltage for the system’s control logic. When VDD or VCC is below the device’s adjustable brown-out threshold, an internal circuit will reset the system by pulling the RESET pin low. The reset pulse length can be programmed to be either 100ms or 250ms, and the active state of the reset can be either high or low.

The X4325S8I-2.7 also features a slow start feature, which is a timed sequence during which the reset pulse is activated. This sequence enables the system to slowly ramp up the supply voltages, and thus prevents sudden inrush currents. In addition, it has an internal watchdog timer to detect any system lockups and reset the system in such cases.

Overall, the X4325S8I-2.7 is an ideal PMIC for a variety of applications due to its low power requirements, high performance, and flexibility in adjusting the reset pulse length and brown-out threshold. It can provide system reset, brown-out protection, and system lock-up detection, and its slow start feature helps prevent sudden inrush currents. Therefore, the X4325S8I-2.7 is an excellent choice for embedded systems and other applications.
