General Description  
The APX823/APX824/APX825A family of supervisors provides circuit initialization and timing supervision, primarily for DSP and  
processor-based systems.  
During power-on, RESET is asserted when supply voltage VCC becomes higher than 1.1V. Thereafter, the supply voltage supervisor  
monitors VCC and keeps RESET active as long as VCC remains below the threshold voltage VTH-. An internal timer delays the return of  
the output to the inactive state (high) to ensure proper system reset. The delay time ,td, starts after VCC has risen above the threshold  
voltage VTH-. When the supply voltage drops below the threshold voltage VTH-, the output becomes active (low) again. No external  
components are required. All the devices of this family have a fixed-sense threshold voltage VTH- set by an internal voltage divider.  
The APX823/APX825A devices incorporate a manual reset input, MR . A low level at MR causes RESET to become active. The  
APX824/APX825A devices include a high-level output RESET. APX823/APX824/APX825A have a watchdog timer that is periodically  
triggered by a positive or negative transition at WDI. When the supervising system fails to retrigger the watchdog circuit within the  
time-out interval, ttout, RESET becomes active for the time period td. This event also reinitializes the watchdog timer. Leaving WDI  
unconnected disables the watchdog.  
In applications where the input to the WDI pin may be active (transitioning high and low) when the APX823/APX824/APX825A asserting  
RESET , the APX823/APX824/APX825A does not return to a non-reset state when the input voltage is above Vt.  
The product spectrum is designed for supply voltage of 2.5V, 3V, 3.3V and 5V. The circuits are available in a SOT25 and SOT26  
packages. The APX823/APX824/APX825A devices are characterized for operation over a temperature range of -40oC to 105oC.
