Introduction to ZSM380CSTZ

The ZSM380CSTZ is a high-performance power monitoring integrated circuit (PMIC) from ZMDI that can be used in a wide range of applications, including automotive, industrial, medical, and consumer electronics. It is specifically designed to monitor the input (Vmains) and output (Vout) voltages of any fixed- or variable-supply DC/DC or AC/DC converters. It can also be used in mixed-signal systems to detect current, power, temperature, and load events.

Application Field and Working Principle of ZSM380CSTZ

The ZSM380CSTZ is best suited for applications requiring the continuous monitoring of supply voltages, such as variable-voltage DC/DC and AC/DC converters. It can also be used to detect short-term transients in Vmains or Vout, or to detect an over-temperature condition.The working principle of the ZSM380CSTZ is as follows. The input can be either a DC voltage (Vmains) or an AC voltage (Vout). The PMIC is designed to monitor the input voltage and to output a reset signal if the voltage exceeds the specified limit. This reset signal can be used to drive the enable pin of a DC/DC or AC/DC converter, or can be used as an interrupt to a microprocessor. The PMIC also has built-in under- and overvoltage, overcurrent, and over-temperature protection. The protection thresholds are set by programming external resistors. The ZSM380CSTZ can be used to detect any transients in Vmains, Vout, and temperature, and can be used to generate a reset signal.In addition, the ZSM380CSTZ features adjustable watchdog timeout, which can be used to monitor the processor and detect a software or hardware failure. The device also features a supply fault alarm with adjustable threshold and a blanking time delay.

Summary

The ZSM380CSTZ is a high-performance power monitoring integrated circuit (PMIC) from ZMDI. It is specifically designed to monitor the input (Vmains) and output (Vout) voltages of any fixed- or variable-supply DC/DC or AC/DC converters, and is best suited for applications requiring continuous monitoring of supply voltages. It also has built-in under- and overvoltage, overcurrent, and over-temperature protection, and features adjustable watchdog timeout, supply fault alarm, and a blanking time delay. Overall, the ZSM380CSTZ offers reliable, cost-effective protection and monitoring for a wide range of applications, making it an ideal power management solution.
