Low Power mP Supervisor
Circuits
Description
The ASM705 / 706 / 707 / 708 and ASM813L are cost effective
CMOS supervisor circuits that monitor power−supply and battery
voltage level, and mP/mC operation.
The family offers several functional options. Each device generates
a reset signal during power−up, power−down and during brownout
conditions. A reset is generated when the supply drops below 4.65 V
(ASM705/707/813L) or 4.40 V (ASM706/708). For 3 V power supply
applications, refer to the ASM705P/R/S/T data sheet. In addition, the
ASM705/706/813L feature a 1.6 second watchdog timer. The
ASM707/708 have both active−HIGH and active−LOW reset outputs
but no watchdog function. The ASM813L has the same pin−out and
functions as the ASM705 but has an active−HIGH reset output. A
versatile power−fail circuit has a 1.25 V threshold, useful in low
battery detection and for monitoring non−5 V supplies. All devices
have a manual reset (MR) input. The watchdog timer output will
trigger a reset if connected to MR.
All devices are available in 8−pin DIP, SO and MicroSO packages.

WDI
Watchdog input. WDI controls the internal watchdog
timer. A HIGH or LOW signal for 1.6 sec at WDI
allows the internal timer to run−out, setting WDO
LOW. The watchdog function is disabled by floating
WDI or by connecting WDI to a high impedance
three−state buffer. The internal watchdog timer
clears when: RESET is asserted; WDI is three−
stated; or WDI sees a rising or falling edge.

Detailed Description
Manual Reset (MR)
A proper reset input enables a microprocessor /
microcontroller to start in a known state. ASM70X and
ASM813L assert reset to prevent code execution errors
during power−up, power−down and brown−out conditions.
The active−LOW manual reset input is pulled high by a
250 mA pull−up current and can be driven low by
CMOS/TTL logic or a mechanical switch to ground. An
external debounce circuit is unnecessary since the 140 ms
minimum reset time will debounce mechanical pushbutton
switches.
By connecting the watchdog output (WDO) and MR, a
watchdog timeout forces RESET to be generated. The
ASM813L should be used when an active−HIGH RESET is
required.
RESET/RESET Timing
The RESET/RESET signals are designed to start a mP/mC
in a known state or return the system to a known state.
The ASM707/708 have two reset outputs, one
active−HIGH RESET and one active−LOW RESET output.
The ASM813L has only an active−HIGH output. RESET is
simply the complement of RESET.
RESET is guaranteed to be LOW with VCC above 1.2 V.
During a power−up sequence, RESET remains low until
the supply rises above the threshold level, either 4.65 V or
4.40 V. RESET goes high approximately 200 ms after
crossing the threshold.
During power−down, RESET goes LOW as VCC falls
below the threshold level and is guaranteed to be under 0.4 V
with VCC above 1.2 V.
In a brownout situation where VCC falls below the
threshold level, RESET pulses low. If a brown−out occurs
during an already initiated reset, the pulse will continue for
a minimum of 140 ms.
Watchdog Timer
The watchdog timer available on the ASM705/706/813L
monitors mP/mC activity. An output line on the processor is
used to toggle the WDI line. If this line is not toggled within
1.6 seconds, the internal timer puts the watchdog output,
WDO, into a LOW state. WDO will remain LOW until a
toggle is detected at WDI.
If WDI is floated or connected to a three−stated circuit, the
watchdog function is disabled, meaning, it is cleared and not
counting. The watchdog timer is also disabled if RESET is
asserted. When RESET becomes inactive and the WDI input
sees a high or low transition as short as 50 ns, the watchdog
timer will begin a 1.6 second countdown. Additional
transitions at WDI will reset the watchdog timer and initiate
a new countdown sequence.
WDO will also become LOW and remain so, whenever
the supply voltage, VCC, falls below the device threshold
level. WDO goes HIGH as soon as VCC transitions above the
threshold. There is no minimum pulse width for WDO as
there is for the RESET outputs. If WDI is floated, WDO
essentially acts as a low−power output indicator.
Power Failure Detection with Auxiliary Comparator
All devices have an auxiliary comparator with 1.25 V trip
point and uncommitted output (PFO) and noninverting input
(PFI). This comparator can be used as a supply voltage
monitor with an external resistor voltage divider. The
attenuated voltage at PFI should be set just below the 1.25
threshold. As the supply level falls, PFI is reduced causing
the PFO output to transit LOW. Normally PFO interrupts the
processor so the system can be shut down in a controlled
manner.

Application Information
Ensuring That RESET is Valid Down to VCC = 0 V
When VCC falls below 1.1 V, the ASM705−708 RESET
output no longer pulls down; it becomes indeterminate. To
avoid the possibility that stray charges build up and force
RESET to the wrong state, a pull−down resistor should be
connected to the RESET pin, thus draining such charges to
ground and holding RESET low. The resistor value is not
critical. A 100 kW resistor will pull RESET to ground
without loading it.
Bi−directional Reset Pin Interfacing
The ASM705/6/7/8 can interface with mP/mC
bi−directional reset pins by connecting a 4.7 kW resistor in
series with the RESET output and the mP/mC bi−directional
RESET pin.
Figure 6. Monitoring +5 V and an
Additional Supply VIN
Monitoring a Negative Voltage
The Power−Fail circuitry can also monitor a negative
supply rail. When the negative rail is OK, PFO will be LOW,
and when the negative rail is failing (not negative enough),
PFO goes HIGH (the opposite of when positive voltages are
monitored). To trigger a reset, these outputs need to be
inverted: adding the resistors and transistor as shown
achieves this. The RESET output will then have the same
sense as for positive voltages: good = HIGH, bad = LOW. It
should be noted that this circuit’s accuracy depends on the
VCC line, the PFI threshold tolerance, and the resistors.
Figure 5. Bi−directional Reset Pin Interfacing
Monitoring Voltages Other Than VCC
The ASM705−708 can monitor voltages other than VCC
using the Power Fail circuitry. If a resistive divider is
connected from the voltage to be monitored to the Power
Fail input (PFI), the PFO will go LOW if the voltage at PFI
goes below 1.25 V reference. Should hysteresis be desired,
connect a resistor (equal to approximately 10 times the sum
of the two resistors in the divider) between the PFI and PFO
pins. A capacitor between PFI and GND will reduce circuit
sensitivity to input high−frequency noise. If it is desired to
assert a RESET for voltages other than VCC then the PFO
output is to be connected to the MR.
