GENERAL DESCRIPTION
The ADM823/ADM824/ADM825 are supervisory circuits that
monitor power supply voltage levels and code execution integrity
in microprocessor-based systems. In addition to providing
power-on reset signals, an on-chip watchdog timer can reset the
microprocessor if it fails to strobe within a preset timeout
period. A reset signal can also be asserted by an external pushbutton, through a manual reset input. The three parts feature
different combinations of watchdog input, manual reset input,
and output stage configuration, as shown in Table 1.
These parts are available in a choice of seven reset threshold
options ranging from 2.19 V to 4.63 V. The reset and watchdog
timeout periods are fixed at 140 ms (minimum) and 1.6 sec
(typical), respectively.
The ADM823/ADM824/ADM825 are available in 5-lead SC70
and SOT-23 packages and typically consume only 5 µA, making
them suitable for use in low power, portable applications.

ADM823/ADM824/ADM825
CIRCUIT DESCRIPTION
The ADM823/ADM824/ADM825 provide microprocessor
supply voltage supervision by controlling the reset input of the
microprocessor. Code execution errors are avoided during
power-up, power-down, and brownout conditions by asserting a
reset signal when the supply voltage is below a preset threshold.
Errors are also avoided by allowing supply voltage stabilization
with a fixed timeout reset pulse after the supply voltage rises
above the threshold. In addition, problems with microprocessor
code execution can be monitored and corrected with a watchdog
timer (ADM823/ADM824). By including watchdog strobe
instructions in microprocessor code, a watchdog timer can
detect whether the microprocessor code breaks down or becomes
stuck in an infinite loop. If this happens, the watchdog timer
asserts a reset pulse that restarts the microprocessor in a known
state. If the user detects a problem with the system’s operation, a
manual reset input is available (ADM823/ADM825) to reset the
microprocessor with an external push-button, for example.
RESET OUTPUT
The ADM823 features an active low, push-pull reset output, and
the ADM824/ADM825 feature dual active low and active high
push-pull reset outputs. For active low and active high outputs,
the reset signal is guaranteed to be logic low and logic high,
respectively, for VCC ≥ 1 V.
The reset output is asserted when VCC is below the reset
threshold (VTH), when MR is driven low, or when WDI is not
serviced within the watchdog timeout period (tWD). Reset
remains asserted for the duration of the reset active timeout
period (tRP) after VCC rises above the reset threshold, after MR
transitions from low to high, or after the watchdog timer times
out. Figure 15 illustrates the behavior of the reset outputs.
VCC
VTH
The ADM823/ADM825 feature a manual reset input (MR)
which, when driven low, asserts the reset output. When MR
transitions from low to high, reset remains asserted for the
duration of the reset active timeout period before deasserting.
The MR input has a 52 kΩ internal pull-up so that the input is
always high when unconnected. An external push-button
switch can be connected between MR and ground so that the
user can generate a reset. Debounce circuitry for this purpose is
integrated on chip. Noise immunity is provided on the MR
input and fast, negative-going transients of up to 100 ns (typical)
are ignored. A 0.1 µF capacitor between MR and ground
provides additional noise immunity.
WATCHDOG INPUT
The ADM823/ADM824 feature a watchdog timer that monitors
microprocessor activity. A timer circuit is cleared with every
low-to-high or high-to-low logic transition on the watchdog
input pin (WDI), which detects pulses as short as 50 ns. If the
timer counts through the preset watchdog timeout period (tWD),
reset is asserted. The microprocessor is required to toggle the
WDI pin to avoid being reset. Failure of the microprocessor to
toggle WDI within the timeout period, therefore, indicates a
code execution error, and the reset pulse generated restarts the
microprocessor in a known state.
In addition to logic transitions on WDI, the watchdog timer is
also cleared by a reset assertion due to an undervoltage condition on VCC or by MR being pulled low. When reset is asserted,
the watchdog timer is cleared and does not begin counting again
until reset is deasserted. The watchdog timer can be disabled by
leaving WDI floating or by three-stating the WDI driver.

APPLICATIONS INFORMATION
WATCHDOG INPUT CURRENT
WATCHDOG SOFTWARE CONSIDERATIONS
To minimize the watchdog input current (and minimize overall
power consumption), leave WDI low for the majority of the
watchdog timeout period. When driven high, WDI can draw as
much as 160 µA. Pulsing WDI low-high-low at a low duty cycle
reduces the effect of the large input current. When WDI is
unconnected, a window comparator disconnects the watchdog
timer from the reset output circuitry so that reset is not asserted
when the watchdog timer times out.
In implementing the microprocessor watchdog strobe code,
quickly switching WDI low-to-high and then high-to-low
(minimizing WDI high time) is desirable for current consumption
reasons. However, a more effective way of using the watchdog
function can be considered.
NEGATIVE-GOING VCC TRANSIENTS
To avoid unnecessary resets caused by fast power supply
transients, the ADM823/ADM824/ADM825 are equipped with
glitch rejection circuitry. The typical performance characteristic
in Figure 12 plots VCC transient duration vs. the transient magnitude. The curves show combinations of transient magnitude
and duration for which a reset is not generated for 4.63 V and
2.93 V reset threshold parts. For example, with the 2.93 V
threshold, a transient that goes 100 mV below the threshold and
lasts 8 µs typically does not cause a reset, but if the transient is
any larger in magnitude or duration, a reset is generated. An
optional 0.1 µF bypass capacitor mounted close to VCC provides
additional glitch rejection.
A low-high-low WDI pulse within a given subroutine prevents
the watchdog timing out. However, if the subroutine becomes
stuck in an infinite loop, the watchdog cannot detect this condition because the subroutine continues to toggle WDI. A more
effective coding scheme for detecting this error involves using a
slightly longer watchdog timeout. In the program that calls the
subroutine, WDI is set high (see Figure 18). The subroutine sets
WDI low when it is called. If the program executes without error,
WDI is toggled high and low with every loop of the program.
If the subroutine enters an infinite loop, WDI is kept low, the
watchdog times out, and the microprocessor is reset.

Both active low and active high reset outputs are guaranteed to
be valid for VCC as low as 1 V. However, by using an external
resistor with push-pull configured reset outputs, valid outputs
for VCC as low as 0 V are possible. For an active low reset output,
a resistor connected between RESET and ground pulls the output
low when it is unable to sink current. For an active high reset
output, a resistor connected between RESET and VCC pulls the
output high when it is unable to source current. A large resistance such as 100 kΩ should be used so that the reset output is
not overloaded when VCC is above 1 V.
