◆ 200ms reset time delay
◆ Three reset signal options
– Active HIGH: IMP706P
– Active LOW: IMP706R/S/T/J
– Active HIGH & LOW outputs: IMP708R/S/T/J
◆ DIP, SO and MicroSO packages
◆ Guaranteed RESET assertion to VCC = 1.1V
The IMP706P/R/S/T/J and IMP708R/S/T/J CMOS supervisor circuits
monitor power-supply and battery voltage level, and µP/µC operation.
A reset is generated when the supply drops below 2.63V (IMP706P/R,
IMP708R), 2.93V (IMP706S, IMP708S), 3.08V (IMP706T, IMP708T) or 4.00
(IMP706J, IMP708J).
The family offers several functional options. Each device generates a
reset signal during power-up, power-down and during brownout
conditions.
In addition, the IMP706P/R/S/T/J feature a 1.6 second watchdog timer.
The watchdog timer output will trigger a reset if connected to MR.
Unlike competitive devices, floating the WDI input pin disables the
watchdog timer.
The IMP708R/S/T/J have both active-HIGH and active-LOW reset outputs but no watchdog function. The IMP706P has the same pin-out and
functions as the IMP706R but has an active-HIGH reset output.
A versatile power-fail circuit, useful in checking battery levels and
non-5V supplies, has a 1.25V threshold. All devices have a manual
reset input.
Applications
All devices are available in 8-pin DIP, SO and the compact MicroSO
packages. The MicroSO package requires 50% less PC board area than
the conventional SO package.

RESET
Function
Manual reset input. The active LOW input triggers
a reset pulse. It is pulled HIGH by a 20kΩ pull-up
resistor. It is compatible with TTL/CMOS signals
when VCC = 5V. It can be shorted to ground
through a mechanical switch. Leave floating or
connect to VCC if the function is not used.
Monitored power supply input.
Ground
Power-fail input voltage monitor. With PFI less than
1.25V, PFO goes LOW. Connect PFI to ground
when not used.
Power-fail output. The output is active LOW and
sinks current when PFI is less than 1.25V. If not
used, leave the pin unconnected.
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.
A rising or falling edge must occur at WDI within
1.6 seconds or WDO goes LOW. The watchdog
function is disabled by floating WDI. The internal
watchdog timer clears when: RESET is asserted;
WDI is three-stated; or WDI sees a rising or falling edge.
Not connected.
Active-LOW reset output. Pulses LOW for 200ms
when triggered, and stays LOW whenever VCC is
below the reset threshold. RESET remains LOW for
200ms after VCC rises above the RESET threshold
or MR goes from HIGH to LOW. A watchdog timeout
will not trigger RESET unless WDO is connected to MR.
Watchdog output. WDO goes LOW when the 1.6
second internal watchdog timer times-out and does
not go HIGH until a transition occurs at WDI. In
addition, when VCC falls below the reset threshold,
WDO goes LOW. Unlike RESET, WDO does not have
a minimum pulse width and as soon as VCC exceeds
the reset threshold, WDO becomes HIGH with no delay.
Active-HIGH reset output. RESET is the inverse of
RESET.

IMP706P/R/S/T/J, IMP708R/S/T/J
Detail Descriptions
RESET/RESET Operation
The RESET/RESET signals are designed to start or return a
µP/µC to a known state.
With VCC above 1.2V, RESET and RESET are guaranteed to be
asserted. During a power-up sequence, the reset outputs remain
asserted until the supply rises above the threshold level. The
resets are deasserted approximately 200ms after crossing the
threshold.
In a brownout situation where VCC falls below the threshold level,
the reset outputs are asserted. If a brownout occurs during an
already initiated reset period, the reset period will extend for an
additional reset period of 200ms.
The IMP708 devices have dual reset outputs, one active LOW and
one active HIGH. The IMP706P has a single active HIGH reset and
the IMP706/R/S/T/J devices have an active LOW reset output.

width is 0.5µs with a 3V VCC input and 0.15µs with a 5V VCC
input. If not used, tie MR to VCC or leave floating.
By connecting the watchdog output (WDO) and MR, a watchdog
timeout forces a RESET to be generated.
Watchdog Timer
A watchdog timer available on the IMP706P/R/S/T/J monitors
µP/µC activity. If activity is not detected within 1.6 seconds on the
Watchdog Input (WDI), the internal timer puts the Watchdog
Output (WDO) into a LOW state. WDO will remain LOW until
activity is detected at WDI.
The watchdog function is disabled, meaning it is cleared and not
counting, if WDI is floated or connected to a three-stated circuit.
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 100ns (VCC = 2.7V)/50ns (VCC = 4.5V), 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 supply voltage output indicator.
Power-failure detection with auxiliary comparator
Manual Reset (MR)
The active-LOW manual reset input is pulled high by an internal
20kΩ pull-up resistor and can be driven low by CMOS/TTL logic
or a mechanical switch to ground. An external debounce circuit is
unnecessary since the 140ms minimum reset time will debounce
mechanical pushbutton switches. The minimum MR input pulse
All devices have an auxiliary comparator with 1.25V trip point.
The output, PFO, is active LOW and the noninverting input is PFI.
This comparator can be used as a supply voltage monitor with an
external resistor voltage divider. As the monitored voltage level
falls, PFI is reduced causing the PFO output to go LOW.
Normally PFO interrupts the processor so the system can be shut
down in a controlled manner.

Application Information
Bi-directional Reset Pin Interfacing
Ensuring That RESET is Valid Down to VCC = 0V
The IMP706/8 can interface with µP/µC bi-directional reset pins
by connecting a 4.7kΩ resistor in series with the RESET output
and the µP/µC bi-directional reset pin.
When VCC falls below 1.2V, the IMP706R/S/T/J and
IMP708R/S/T/J RESET reset outputs no longer pull down; it
becomes indeterminate. To avoid the possibility that stray charges
could 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. The resistor value is not critical. A 100kΩ resistor will pull RESET to ground without loading it.

Monitoring Voltages Other Than VCC
The IMP706/708 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 PFI input, the PFO (output) will go
LOW if the divider voltage goes below its 1.25V 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 in addition to the PFO flag, this may be achieved by
connecting the PFO output to MR.
