詳細說明

The DS1232N+ is a MicroMonitor™ Chip that plays a crucial role in monitoring the power supply, software execution, and external override for a microprocessor. It incorporates a precision temperature-compensated reference and comparator circuit to keep a close eye on the status of VCC. In the event of an out-of-tolerance condition, the chip generates an internal power fail signal, triggering a reset to the active state. Following this, when VCC returns to an in-tolerance condition, the reset signals remain in the active state for a minimum of 250ms. This allows both the power supply and processor to stabilize, ensuring optimal performance and reliability

主要特徵

  • High-temperature operation up to 125°C
  • Silicon-based protection against ESD and surge pulses
  • Fault-tolerant operation during power transients
  • Simplified design with no external components needed
  • Compact size for space-saving applications

常見問題解答

What is DS1232N+?

The DS1232N+ is a precision watch dog timer IC (Integrated Circuit) designed by Maxim Integrated. It is used for monitoring and resetting microcontroller or system operation, ensuring proper functioning and reliability.

How Does DS1232N+ Work?

The DS1232N+ operates by continuously monitoring the system and generating a reset signal if it does not receive a periodic control input within a specified time window. This helps prevent system lock-up or malfunctions by initiating a reset sequence when necessary.

How Many Pins does DS1232N+ have and What are the Functions of the Pinout Configuration?

The DS1232N+ is housed in an 8-pin DIP (Dual Inline Package) package. The pinout configuration includes:

  • VCC: Supply voltage pin.
  • GND: Ground pin.
  • GND: Ground pin.
  • MR: Reset input pin.
  • OUT: Reset output pin.
  • Delay: Delay pin for setting the timeout period.
  • Timing Capacitor: Connects to an external timing capacitor for setting the timeout period.

What are the Pros and Cons of DS1232N+?

Pros:

  • Reliable System Reset: Ensures system reliability by monitoring and resetting operation.
  • Simple Integration: Easy to integrate into systems for added protection.
  • Low Power Consumption: Operates with low power consumption, suitable for battery-powered devices.
  • Wide Operating Voltage Range: Supports a wide voltage range for versatile applications.

Cons:

  • Single Functionality: Designed specifically for watchdog timer functionality, may not offer additional features.
  • External Components: Requires an external timing capacitor for setting the timeout period.

Are There Any Equivalents/Alternatives to DS1232N+ for Recommendation?

  • The MAX6369 from Maxim Integrated is a similar watchdog timer IC.
  • Alternatives to the DS1232N+ include the MC3422 from ON Semiconductor and the TPS3430 from Texas Instruments.
