The DS1232N is an IC component designed for use in microprocessor systems as a monitor for detecting power supply voltage levels and generating a system reset signal whenever these levels deviate from the desired range. It acts as a supervisor circuit to ensure proper operation and protection of the microprocessor.
Key Features of the DS1232N are as follows:
1. Power Supply Voltage Monitoring: The DS1232N continuously monitors the power supply voltage using an internal comparator. If the supply voltage falls below a predefined threshold, typically 4.55V, the chip detects a power failure condition.
2. Reset Generation: Upon detection of a power failure or a voltage drop below the threshold, the DS1232N generates a reset signal. This reset signal remains active for a specified period, typically 250ms, after the supply voltage has returned to an acceptable level.
3. Manual Reset Input: The IC provides a manual reset input pin to allow users to forcefully trigger a system reset. When this pin is asserted (pulled low), the reset line is activated independently of the power supply conditions, enabling a manual restart whenever required.
4. Active-High and Active-Low Reset Output: The DS1232N offers two reset output pins, one active-high and one active-low, allowing compatibility with different microprocessor systems. The active-high reset output signals a system reset when it is asserted, while the active-low reset output signals a reset when it is de-asserted
