詳細說明

The DS1232 MicroMonitor Chip monitors three vital conditions for a microprocessor: power supply, software execution, and external override. First, a precision temperature-compensated reference and comparator circuit monitors the status of VCC. When an out-of-tolerance condition occurs, an internal power fail signal is generated which forces reset to the active state.FEATURES■ Halts and restarts an out-of-control microprocessor■ Holds microprocessor in check during power transients■ Automatically restarts microprocessor after power failure■ Monitors pushbutton for external override■ Accurate 5% or 10% microprocessor power supply monitoring■ Eliminates the need for discrete components■ Space-saving, 8-pin mini-DIP■ Optional 16-pin SOIC surface mount package■ Industrial temperature -40°C to +85°C available, designated N

常見問題解答

What is DS1232N?

The DS1232N is a precision voltage monitor and microprocessor supervisory circuit designed by Maxim Integrated. It is commonly used to monitor the power supply voltage of microcontroller-based systems and to provide a reset signal during power-up and power-down conditions.

How Does DS1232N Work?

The DS1232N works by continuously monitoring the power supply voltage of a microcontroller or digital system. When the voltage drops below a preset threshold, the DS1232N asserts a reset signal to initialize or reset the microcontroller, ensuring proper operation and system integrity. It helps prevent erratic behavior and software glitches during power fluctuations.

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: Power supply voltage input pin.
  • GND: Ground pin.
  • MR: Manual reset input pin.
  • RESET_OUT: Active-low reset output pin.
  • Delay: Delay capacitor pin for adjusting the reset timeout delay.

What are the Pros and Cons of DS1232N?

Pros:

  • Reliable Power Monitoring: Ensures stable and reliable operation by monitoring the power supply voltage.
  • Manual Reset Input: Allows for external manual reset capability, providing flexibility in system control.
  • Low Power Consumption: Operates with very low power, suitable for battery-powered applications.
  • Simple Configuration: Requires minimal external components and straightforward configuration for ease of use.
  • Robust Design: Offers built-in hysteresis for noise immunity and reliable reset operation.

Cons:

  • Fixed Threshold: The voltage threshold for the reset signal is fixed and may not be adjustable in some applications.
  • Single Voltage Monitoring: Monitors a single power supply voltage and may not be suitable for systems with multiple supply rails.
  • Package Size: The 8-pin DIP package may require more board space compared to surface-mount packages.

Are There Any Equivalents/Alternatives to DS1232N for Recommendation?

  • The MAX1232 from Maxim Integrated is a similar microprocessor supervisory circuit offering comparable features.
  • Alternatives to the DS1232N include the ADM708 from Analog Devices and the TPS3600 from Texas Instruments.
