DS1233DZ-15+ PMIC - Супервизоры от Maxim Integrated

The DS1233DZ-15+ is a precision voltage supervisor and reset controller manufactured by Maxim Integrated, designed to ensure reliable operation of microcontrollers and other digital systems. This device is particularly useful in applications where power supply fluctuations can lead to system instability or data corruption.

Key Features:

1. Voltage Monitoring: The DS1233DZ-15+ monitors the supply voltage and provides a reset signal when the voltage falls below a predetermined threshold. This ensures that the microcontroller or digital logic does not operate under unsafe voltage conditions.

2. Reset Threshold: The device has a fixed reset threshold of 4.63V, making it suitable for 5V systems. This threshold is critical for ensuring that the system only starts operating when the voltage is stable and within the specified range.

3. Active-Low Reset Output: The reset output is active-low, meaning that it goes low when a reset condition is detected. This output can be connected directly to the reset pin of a microcontroller, ensuring that the microcontroller is held in a reset state until the supply voltage is stable.

4. Reset Timeout: The DS1233DZ-15+ features a built-in reset timeout period, which is typically around 200 milliseconds. This delay allows the power supply to stabilize after a power-up or brownout condition before releasing the reset signal.

5. Low Power Consumption: The device is designed to operate with low power consumption, making it suitable for battery-powered applications. This efficiency helps extend the battery life of portable devices.

6. Temperature Range: The DS1233DZ-15+ operates over a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial and automotive applications where temperature variations can be significant.

7. Package Type: The device is available in a compact 8-pin SOIC (Small Outline Integrated Circuit) package, which is ideal for space-constrained designs.

8. Applications: Common applications for the DS1233DZ-15+ include microcontroller reset circuits, power supply monitoring, automotive electronics, and any system where reliable power management is critical.

Electrical Characteristics:

• Supply Voltage Range: The device operates from a supply voltage of 4.5V to 5.5V.
• Reset Threshold Voltage: 4.63V (typical).
• Reset Timeout Period: Approximately 200 ms (typical).
• Quiescent Current: Typically low, ensuring minimal impact on battery life.

Conclusion:

The DS1233DZ-15+ from Maxim Integrated is a robust and reliable solution for voltage supervision and reset control in digital systems. Its combination of precise voltage monitoring, low power consumption, and wide operating temperature range makes it an excellent choice for a variety of applications, ensuring that electronic systems operate safely and effectively under varying power conditions.
