Working Principles
The DS1232LPS is designed to monitor the supply voltage of a system. When the voltage falls below the reset threshold, the IC asserts an active-low reset signal. This ensures that the system remains in a known state during power-up and power-down events. The reset output remains asserted until the supply voltage rises above the threshold and the reset timeout period elapses.
