DS1232N+ Analog Devices

The DS1232N+ with Supervisory Circuits MicroMonitor Chip is a part manufactured by Analog Devices. It is a highly integrated non-volatile, low-power CMOS Supervisory Circuit designed specifically for portable and power-sensitive applications. It allows for frequent monitoring of system parameters. It combines a Low-Oscillator, AT (Accurate Timing) circuit, Power-On Reset output, Backup Circuit, Watchdog Timer and Timer functions. The DS1232N+ monitors the main power supply voltage and generates power-on reset (POR) alerts as soon as the main supply voltage drops below a preset threshold. It also offers an on-chip, highly accurate oscillator for generating periodic watchdog signals if a master controller fails to respond to automatically reset the system. This helps to improve system reliability and avoids system failures due to software locks. Its advanced design allows it to operate from a wide range of supply voltages, making it suitable for a variety of applications.
