GENERAL DESCRIPTION
TheADM6316/ADM6317/ADM6318/ADM6319/ADM6320/
ADM6321/ADM6322 are supervisory circuits that monitor
power supply voltage levels and code execution integrity in
microprocessor-based systems. As well as providing power-on
reset signals, an on-chip watchdog timer can reset the micro-
processor if it fails to strobe within a preset timeout period. A
reset signal can also be asserted by an external push-button
through a manual reset input. The seven parts feature different
combinations of watchdog input, manual reset input, and
output stage configuration, as shown in Table 1.
Each part is available in a choice of 26 reset threshold options
ranging from 2.5 V to 5 V in 100 mV increments. There are also
four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms
(minimum) and four watchdog timeout options of 6.3 ms, 102 ms,
1600 ms, and 25.6 sec (typical).
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/
ADM6321/ADM6322 are available in 5-lead SOT-23 packages
and typically consume only 3 μA, making them suitable for use
in low power portable applications.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322
CIRCUIT DESCRIPTION
The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/
ADM6321/ADM6322 provide microprocessor supply voltage
supervision by controlling the microprocessor’s reset input.
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 and 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 (ADM6316/ADM6317/
ADM6318/ADM6320/ADM6321). If the user detects a problem
with the system’s operation, a manual reset input is available
(ADM6316/ADM6317/ADM6319/ADM6320/ADM6322) to
reset the microprocessor by means of an external push-button,
for example.
MANUAL RESET INPUT
The ADM6316/ADM6317/ADM6319/ADM6320/ADM6322
feature a manual reset input (
) which, when driven low,
transitions from low to high,
MR
asserts the reset output. When
MR
reset remains asserted for the duration of the reset active
timeout period before deasserting. The input has a 52 kΩ,
MR
internal pull-up so that the input is always high when uncon-
nected. An external push-button switch can be connected
between
and ground so that the user can generate a reset.
MR
Debounce circuitry for this purpose is integrated on-chip. Noise
immunity is provided on the input, and fast, negative-going
MR
transients of up to 100 ns (typical) are ignored. A 0.1 μF capacitor
between and ground provides additional noise immunity.
MR
WATCHDOG INPUT
RESET OUTPUT
The ADM6316/ADM6317/ADM6318/ADM6320/ADM6321
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.
The ADM6316 features an active-low, push-pull reset output,
while the ADM6317/ADM6321/ADM6322 have active-high,
push-pull reset outputs. The ADM6318/ADM6319 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 down to 1 V.
The reset output is asserted when VCC is below the reset
threshold (VTH), when
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
is driven low, or when WDI is not
MR
As well as logic transitions on WDI, the watchdog timer is also
cleared by a reset assertion due to an undervoltage condition on

out. Figure 16 illustrates the behavior of the reset outputs.

being pulled low. When reset is asserted, the
MR
watchdog timer is cleared and does not begin counting again
until reset deassserts. The watchdog timer can be disabled by
leaving WDI floating or by three-stating the WDI driver.

OPEN-DRAIN RESET OUTPUT
Figure 17. Watchdog Timing Diagram
The ADM6320/ADM6321/ADM6322 have an active-low, open-
drain reset output. This output structure requires an external
pull-up resistor to connect the reset output to a voltage rail no
higher than 6 V. The resistor should comply with the micro-
processor’s logic low and logic high voltage level requirements
while supplying input current and leakage paths on the
RESET
line. A 10 kΩ resistor is adequate in most situations.

APPLICATION INFORMATION
WATCHDOG INPUT CURRENT
WATCHDOG SOFTWARE CONSIDERATIONS
To minimize watchdog input current (and minimize overall
power consumption), leave WDI low for the majority
In implementing the microprocessor’s 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.
of the watchdog timeout period. When driven high, WDI can
draw as much as 160 μA. Pulsing WDI low to high to 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.
A low to high to 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 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. 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 (see Figure 19).
NEGATIVE-GOING VCC TRANSIENTS
To avoid unnecessary resets caused by fast power supply
transients, the ADM6316/ADM6317/ADM6318/ADM6319/
ADM6320/ADM6321/ADM6322 are equipped with glitch
rejection circuitry. The typical performance characteristic in
Figure 13 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 bigger in magnitude or duration, a reset is
generated. An optional 0.1 μF bypass capacitor mounted close
to VCC provides additional glitch rejection.

the output low when it is unable to sink current. For the active-
high case, 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 it does not
overload the reset output when VCC is above 1 V.

1 Complete the ordering code by inserting reset timeout, watchdog timeout (ADM6316/ADM6317/ADM6318/ADM6320/ADM6321), and reset threshold suffixes from
Table 5 to Table 7. No watchdog timeout is available for ADM6319/ADM6322.
2 Contact sales for the availability of nonstandard models. See Table 8 for a list of standard models.
3 A minimum of 12,000 (4 reels) must be ordered.
4 Z = Pb-free part.
