FEATURES
GENERAL DESCRIPTION
• Zero voltage start-up
The SAA1504T is manufactured in a BCD Power Logic 70
process and is intended to be used as a protection circuit
for single cell Li-ion battery packs. The current and voltage
ratings are especially designed for use in battery packs for
portable telephones such as GSM.
• Discharge and charge overcurrent protection
• Automatic release of current protection at removal of
charger or load
• Low current consumption in normal operating mode
The circuit continuously monitors the battery voltage,
current and junction temperature and will disconnect the
battery in case of an overload situation:
• Very low current consumption when battery voltage is
lower than 2.3 V
• Accurate voltage detection levels
• Overdischarge protection prevents deep discharge of
the cell; deep discharge of a Li-ion cell degrades the life
cycle
• Continuous monitoring of battery voltage and charge or
discharge current
• External power FETs are driven with an elevated supply
voltage, reducing the on-resistance
• Overcharge protection for safety reasons
• Overcurrent protection on charge or discharge current
rate
• Able to accommodate 20 V charge voltage
• Read out of charge (disable) status
• Temperature protection for preventing charge or
discharge at high temperatures
• Small package (SO8)
• Low external components count
• Short circuit protection.
• Temperature protection
It must be stated that this is a safety IC to be integrated
inside a battery pack. It is not primarily intended as an end
of charge provision.
• Charger reverse connection protection.

FUNCTIONAL DESCRIPTION
SYMBOL PIN
The basic function of the SAA1504T is to protect a single
Li-ion cell against overcharge and overdischarge for
reasons of life time and safety. The voltage across the cell
terminals (Vbat) is monitored continuously and compared
to an accurate internal reference voltage.

The circuit diagram (see Fig.3) of a Li-ion battery pack
shows the SAA1504T and 2 power NMOS transistors
which are connected in anti series. Both transistors must
have their backgate connected to their source, resulting in
2 backgate diodes in anti series.
The timing diagram (see Fig.6) shows the detection levels
for the various modes of operation.
Battery voltage between 2.6 and 4.18 V
handbook, halfpage
VSS 1
The safety IC is in the normal operating mode for
Vbat = 2.6 to 4.18 V, a charge or discharge current below
the current-protection level and a junction temperature
below the temperature protection activation level. In this
mode transistors SW1 and SW2 are driven with an
elevated supply voltage (with a charge pump) which
guarantees a low on-resistance in the main current path.
This is important for fully utilizing the high energy density
of the Li-ion battery technology.

Battery voltage below 2.3 V
Zero voltage start-up
When Vbat < 2.3 V the safety IC is in the Power-down
mode: SW2 is open to block a further discharge.
The safety IC has to be able to charge the battery at 0 V.
This means that when connecting a charger in case of a
completely empty battery, SW1 has to be open.
The battery voltage will increase stepwise, because of the
sudden disconnection of the load. The safety IC will not
re-enter the normal operating mode at this event unless
the battery voltage exceeds the power-down release level
of 2.6 V and a charge current is present. So when no
charger is present in the Power-down mode, the safety IC
stays in this mode, independent of the battery voltage.
In the Power-down mode output CO is connected via a
diode to VCC, so that the charge transistor will be active
when VVM is negative.
Maximum charge or discharge current and
temperature protection
Connecting a charger in the Power-down mode is detected
by a negative voltage on pin VM. Because the voltage at
pin VM is defined by a charge current via the backgate
diode of SW2, a charge current of a few nAs is already
detected. When a charge current is detected and
Vbat > 2.6 V, the system will go from the Power-down
mode to the normal operating mode.
When the maximum charge or discharge current is
exceeded or when the maximum temperature is detected
the disable mode is activated and will open both switches.
Exceeding the maximum charge or discharge current is
detected by a voltage drop or rise on pin VM when both
switches are closed.
A release of this mode can only be achieved by removing
the load (or charger) and at a junction temperature below
60 °C. The disable mode is followed by a return to its
previous mode.
In the Power-down mode the supply current is reduced to
150 nA (typical value) for minimizing the discharge of the
battery by the safety IC. This is achieved by disabling all
analog circuitry, except the circuitry for detecting the
presence of a charger and for detecting Vbat > 2.6 V.
Because the charge pump is disabled and battery
charging should be possible, SW1 is switched on with a
reduced Vgs voltage.
Normal operating mode
In case of correct temperature, battery voltage and charge
or discharge current, the system will be in the normal
operating mode (see Fig.4).
Battery voltage above 4.18 V
Both the charge and discharge outputs will be HIGH
(CO = 1 and DO = 1), so both switches are closed.
When the battery is charged to Vbat > 4.18 V, the safety IC
will enter the charge inhibit mode: SW1 is open and
charging is disabled.
Power-down mode
When Vbat < 2.3 V the safety IC will enter the Power-down
mode (see Fig.4). The power-down detection level of 2.3 V
has a delay of 5 ms (typical value). The Power-down mode
will also be entered without delay when Vbat < 1.9 V.
Connecting a load in the charge inhibit mode is detected
by the reversal of the voltage across SW1 and will
immediately close SW1, so entering the discharge enable
mode. A short time is needed to charge the gate of SW1.
During this time the backgate diode between drain and
source of SW1 conducts.
In this mode only charging of the battery is allowed
(CO = 1 and DO = 0).
The safety IC will remain in the discharge enable mode
unless:
The safety IC will return to the normal operating mode as
soon as Vbat > 2.6 V and a charge current is detected at
the same time.
• Vbat < 3.95 V, which results in re-entering the normal
operating mode. This transition is not externally
noticeable, because both switches remain closed.
• A charger is connected, which will immediately open
SW1. As an additional safety precaution Vbat > 4.18 V
also yields the same reaction, because otherwise a
small current of a charger may be undetected, leading to
overcharging the Li-ion cell.

SAA1504T
From the discharge enable mode the charge inhibit mode
will be entered again as soon as a charge current is
detected or Vbat > 4.18 V. The detection of a higher
voltage than 4.18 V is necessary. If the battery is charged
with a very low charge current, the safety IC will not switch
from the discharge enable mode to the charge inhibit
mode. Eventually, the safety IC will enter the charge inhibit
mode if the battery is overcharged to Vbat > 4.18 V
because of a small charge current.
Charge inhibit mode
When Vbat > 4.18 V, the charge inhibit mode will be
entered (see Fig.4). At this mode the battery can only be
discharged (CO = 0 and DO = 1).
The excess charge delay can be set by means of an
external capacitor. The delay is then defined as:
ted(det) = 30 × CCEXT with ted(det) in ms and CCEXT in nF.
When Vbat < 3.95 V, the safety IC will return from the
charge inhibit mode to the normal operating mode.
When Vbat < 3.95 V the safety IC will return from the
discharge enable to the normal operating mode.
The charge inhibit mode will also be entered as soon as a
charge current is detected in the discharge enable mode
If the safety IC is in the charge inhibit mode, it will usually
go to the normal operating mode via the discharge enable
mode. But if the system is in the charge inhibit mode and
the battery pack is stored for several years, the battery
voltage can drop because of the battery discharge by the
safety IC and the self discharge of the battery. So a
voltage drop of the battery is possible, without detecting a
discharge current. Because of this, the normal operating
mode should also be entered from the charge inhibit mode
when Vbat < 3.95 V and not only from the discharge enable
mode. In this way, charging a battery is always possible if
Vbat < 3.95 V.
Discharge enable mode
When the safety IC is in the charge inhibit mode, charging
of the battery is disabled because SW1 is open. Initially
discharge of the battery will then occur via the backgate
diode of SW1. The load voltage will be approximately 0.6 V
lower and dissipation of the backgate diode of SW1 will
occur. It is preferable to close both switches at that time
without allowing charging of the battery until Vbat < 3.95 V.
If a discharge current is detected in the charge inhibit
mode, the system will activate the discharge enable mode,
closing both switches.

Disable mode
The delay of the current protection as a function of the
sense voltage VVM (for charge and discharge) is given in
Fig.5.
When the charge or discharge current exceeds the
specified maximum value, the disable mode is entered.
Detection of the maximum charge or discharge current is
only activated when the outputs are HIGH (CO = 1 and
DO = 1) as explained next.
The disable mode is also entered when the junction
temperature exceeds 100 °C. When the temperature
drops below 60 °C and at the absence of a charger or load,
the safety IC will return to its previous mode.
If the safety IC is in the Power-down mode and a charge
current is detected (e.g. VVM = −0.6 V) the normal
operating mode will be entered when Vbat > 2.6 V.
Because of a minimum time in which the gate capacitors
have to be charged, VVM = −0.6 V for a small period, when
the safety IC is already in the normal operating mode.
VVM = −0.6 V could also occur when the battery is charged
with a current exceeding the maximum charge current.
To prevent that a maximum charge current is detected
when coming from the Power-down mode a delay is
included to ensure charging of both outputs CO and DO.
So entering of the disable mode is enabled when both
outputs CO and DO are fully charged or after a certain
delay. The delay is necessary to activate the current
protection even in case the outputs CO or DO can not be
fully charged.

SOLDERING
If wave soldering is used the following conditions must be
observed for optimal results:
Introduction to soldering surface mount packages
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
Reflow soldering
The footprint must incorporate solder thieves at the
downstream end.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
• For packages with leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Wave soldering
Manual soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
To overcome these problems the double-wave soldering
method was specifically developed.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
