Power ICs, or PMICs, are key components in modern electronic systems. They provide essential functions such as power regulation, protection, and monitoring. Supervisors are an important subcategory of power management ICs (PMICs). Supervisors monitor system environment conditions such as voltage and temperature, and assert system reset, power-good, and other alert signals to ensure proper system performance. The DS1233DZ-10 is a supervisor from Maxim Integrated that manages system reset operations in critical control applications.

Features

• Configurable reset timeout duration
• Flexible reset thresholds
• Generates open drain reset output
• Powered by 3.2 to 5.5V supply voltage
• Operating temperature range: -40˚C to +125˚C
• Supports configurable reset pulse widths

Applications

• HVAC systems
• Renewable energy systems
• Industrial controls
• Network infrastructure
• Medical systems

Working Principle

Reset management ICs like the DS1233DZ-10 offer application-specific customization, making them essential for unpredictable or time-varying environments, like those faced by renewable energy, industrial, and medical systems. The DS1233DZ-10 is an I²C/SMBus-compatible device with several configurable parameters. It can be programmed to generate a reset signal if an input voltage exceeds a set threshold or if a selected timeout period, set by the user, elapses. To accommodate a range of reset policies, the DS1233DZ-10 also supports flexible reset pulse widths, power-good debounce times, and enable/disable thresholds.

Conclusion

The DS1233DZ-10 from Maxim Integrated is an I²C/SMBus-compatible supervisor that provides application-specific customization. Its features and design enable superior protection and monitoring of system activity in a broad range of control applications such as HVAC systems, renewable energy systems, industrial controls, and more. Configurable parameters include reset thresholds, timeout periods, reset pulse widths, power-good debounce times, and enable/disable thresholds, giving users the power to design their own tailored reset policies.
