Manufacturer:NS Description:The microprocessor monitor circuitry of the LM1875T provides three basic functions. 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 the reset to the active state. When VCC returns to an in-tolerance condition, the reset signals are kept in the active state for 250 ms to allow the power supply and processor to stabilize. The second microprocessor monitor function is pushbutton reset control. The LM1875T debounces a pushbutton input and guarantees an active reset pulse width of 250 ms. The third function is a watchdog timer. The LM1875T has an internal timer that forces the reset signals to the active state if the strobe input is not driven low prior to watchdog time-out. |
