ZSH330C

Block diagram of ZSH330C Supervisors as per Zener, Figure 1.

The ZSH330C supervisor, which is designed and manufactured by Zener, is designed to provide long-term reliability and accurate voltage detection for digital ICs and power ICs. It consists of an input circuit, an output circuit, and a counter and logic block.

The input circuit consists of an external voltage clamping diode connected to a voltage detector. When a voltage is applied to the diode, a voltage waveform is generated that is transmitted through the detector and a timer circuit. The voltage waveform will be compared with the expectations of the system to determine if the voltage is within the expected range.

The output circuit is made up of a transformer, a diode and a protection circuit. This circuit is responsible for the output stage protection from the overvoltage and undervoltage events. The transformer is used to transfer the input voltage to the output level. The protection circuit is responsible for providing short-circuit and overcurrent protection for the output device.

The counter and logic block is responsible for the operation of the supervisor. It contains a counter that keeps track of the number of cycles that have gone by since the supervisor was powered up. This is used to trigger the reset signal if the applied voltage is out of tolerance. It also contains logic that allows the supervisor to be programmed such that it can be used in different applications.

Applications of ZSH330C Supervisors include long-term reliable system power-down circuits, low voltage reset, low battery alerting and system reset circuits. It is also used in charge controllers, battery-operated systems, power modules, LED drivers and many other power management applications. Some of the key features of the device include: accurate voltage supervision, low power consumption, overvoltage protection, undervoltage protection, low standby current, multiple levels of supervision and a wide operating range.

ZSH330C Supervisors provide reliable and accurate voltage supervision for applications that require constant monitoring and timely response from the system. They are designed to provide a long-term reliable power-down solution and can be used in a variety of applications. Moreover, the device provides multiple levels of protection and wide operating temperatures, enabling it to be used in harsh environment applications.
