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 V_CCbecomes higher than 1.1V. Thereafter, the supply voltage supervisor

monitors V_CCand keeps RESET active as long as V_CCremains below the threshold voltage V_TH-. An internal timer delays the return of

the output to the inactive state (high) to ensure proper system reset. The delay time ,t_d, starts after V_CChas risen above the threshold

voltage V_TH-. When the supply voltage drops below the threshold voltage V_TH-, the output becomes active (low) again. No external

components are required. All the devices of this family have a fixed-sense threshold voltage V_TH-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 -40^oC to 105^oC.
