Functional Features

• Power Supply Monitoring: Monitors the input voltage and generates a reset signal when it falls below a certain threshold.
• Adjustable Reset Threshold: Allows the user to set the desired voltage level at which the reset signal is triggered.
• Adjustable Reset Timeout: Provides flexibility in setting the duration for which the reset signal remains active after the input voltage rises above the threshold.
• Power-On Reset Delay: Ensures a stable power supply before releasing the reset signal.
• Low Quiescent Current: Consumes minimal current during normal operation, reducing power consumption.

Advantages

• Provides reliable power supply monitoring and protection.
• Adjustable reset threshold and timeout allow customization for different system requirements.
• Power-on reset delay ensures stability during power-up.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited output current capacity (200mA).
• Requires external components for proper operation.
• Not suitable for high-power applications.

Working Principles

The MC34160P operates by continuously monitoring the input voltage. When the voltage falls below the user-defined threshold, it triggers a reset signal. The reset signal remains active for the duration set by the user using the adjustable reset timeout feature. After the input voltage rises above the threshold and the reset timeout period elapses, the reset signal is deactivated. The power-on reset delay ensures that the reset signal is not released immediately upon power-up, allowing the power supply to stabilize.

Application Field Plans

The MC34160P is commonly used in various electronic systems where reliable power supply monitoring and protection are crucial. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Industrial control systems
3. Automotive electronics
4. Telecommunications equipment
5. Medical devices
6. Consumer electronics

Alternative Models

• MAX823: Similar power supply supervisory circuit with adjustable reset threshold and timeout.
• TPS3839: Power supply supervisor with fixed reset threshold and adjustable reset timeout.
• ADM6315: Microprocessor supervisory circuit with adjustable reset threshold and timeout.

These alternative models offer similar functionality and can be considered as alternatives to the MC34160P based on specific requirements and preferences.
