X5329S8Z-2.7 is a highly integrated central processor voltage supervisor designed with PMIC (power management integrated circuit) and supervisors. This product, developed by Chongqing Company, consists of a high-performance window watchdog circuit, a supervisor circuit, an analog voltage detector and a power-on reset circuit.

The X5329S8Z-2.7 application field includes a wide range of applications such as personal computer power management, mainboard power supply, automotive electronics, and communication equipment. This voltage supervisor is an ideal solution for the efficient, low-cost and reliable voltage monitoring.

The working principle of X5329S8Z-2.7 is divided into different stages. Firstly, when the power of the main power supply is turned on, the main power supply starts to output its voltage. The output voltage is monitored by the window watchdog circuit and the supervisor circuit in this voltage supervisor, and whenever the voltage is out of the predetermined ranges, the supervisor circuit generates an active reset signal.

Secondly, the analog voltage detector contains high-precision voltage reference, to provide an accurate and reliable voltage output. It monitors the input voltage against an adjustable threshold voltage, and it can monitor 5-channel (ground current monitor, PFET current monitor, independent open-drain output power state). When the set voltage levels exceed the threshold voltage, the voltage detector will detect it and output an external reset signal. Moreover, the voltage detector also contains an adjustable delay time that allows the user to set the minimum reset delay time.

Thirdly, the power-on reset circuit controls the reset signals from the supervisor and voltage detector. This circuit is designed with a low active reset inrush current, a high active reset stand-by current and a low active reset stand-by current. When the voltage levels are in the normal range, the active reset signal will be disabled and the X5329S8Z-2.7 will remain in a low power consumption state.

To sum up, the X5329S8Z-2.7 is an ideal voltage supervisor with a wide application field and a highly integrated circuit design. Its window watchdog circuit, supervisor circuit, analog voltage detector and power-on reset circuit offers efficient, low-cost and reliable voltage monitoring, greatly reducing the energy consumption of the system.
