GENERAL DESCRIPTION
The NE56610/11/12-XX series is a family of devices designed to
generate a reset signal for a variety of microprocessor and logic
systems. Accurate reset signals are generated during momentary
power interruptions or when ever power supply voltages sag to
intolerable levels. The NE56610/11/12 incorporates an internal timer
to provide reset delay and ensure proper operating voltage has been
attained. In addition, a manual reset pin (M/R) is available. An Open
Collector output topology provides adaptability for a wide variety of
logic and microprocessor systems.
NE56610/11/12 is available in the 5-lead small outline surface mount
package (SOP003.

TECHNICAL DESCRIPTION
The NE56610/11/12-XX devices comprise a family of devices
designed to monitor the supply voltage and output a RESET signal
whenever the supply voltage sags below an acceptable system level
or when supply voltage interruptions occur. Each of the three
devices of the family are available with a fixed detection threshold
voltage (2.5, 2.7, 2.9, 3.9, 4.2, 4.5 V). The device family is very
versatile and adaptable for a wide variety of applications.
Incorporating a delay in the output RESET prevents output
oscillations from occurring and helps ensure system supply voltages
are adequate and stabilized before the microprocessor is placed into
full operation. Where there is little or no delay in output RESET,
there is a possibility of output oscillations occurring, particularly
where high impedance supply sources are used.
In addition, the devices have a manual reset (M/R) pin, which when
pulled to a HIGH voltage state, forces a RESET signal at the output.
The M/R pin should always be connected to ground when manual
reset is not used.
The devices are designed to have a detection threshold hysteresis
of 50 mV typical. When the supply voltage delivered to the device
falls to the detection sense level (V ), a RESET is output and not
S
released until the supply voltage rises to the level of V or greater.

Internally, the devices incorporate a fixed internal digital timer which,
when activated, produces a fixed internal delay before a RESET
signal is output. This delay can not be influenced externally. The
NE56510 has an internal delay of 50 ms, while the NE56611 and
NE56612 have internal delays of 100 ms and 200 ms respectively.
disadvantage, it is an advantage in many sensitive applications. The
open drain output topology does not have the capability of sourcing
reset current to a microprocessor when both are operated from a
common supply. It is for this reason the device family offers a safe
inter-connect to a wide variety of microprocessors.

Figure 19. Manual Reset circuit
When a manual reset is used, it is suggested a resistor (R ) be
PU
connected from the M/R pin to ground so as to provide a pull-down
ground reference for the M/R pin when not in use. This will reduce
the possibility of an induced erroneous voltage being imposed on
the M/R pin. This can be a solution in noisy applications where the
manual reset line is of considerable length and subject to picking up
induced voltages. The M/R pin can be pulled to a HIGH voltage
state whenever a manual reset is imposed. The only disadvantage
to this is a small amount of additional current flow through the
pull-down ground reference resistor when the M/R pin is pulled to a
HIGH state.

As a precaution, a clamp diode is placed from the M/R pin to ground
to ensure that the pin does not go below –0.3 V.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see
the relevant data sheet or data handbook.
Limitingvaluesdefinition— Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or more of the limiting
values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given
in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips Semiconductors make no
representation or warranty that such applications will be suitable for the specified use without further testing or modification.
Disclaimers
Life support — These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be
expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications do so at their own risk and agree
to fully indemnify Philips Semiconductors for any damages resulting from such application.
Right to make changes — Philips Semiconductors reserves the right to make changes in the products—including circuits, standard cells, and/or software—described
or contained herein in order to improve design and/or performance. When the product is in full production (status ‘Production’), relevant changes will be communicated
