Charging System Safety Circuit
ISL9211B
Features
The ISL9211B is an integrated circuit (IC) optimized to provide
a redundant safety protection to a Li-ion battery charging
system. The IC monitors input voltage, battery voltage, and
charge current. When any of these parameters exceeds its
limit, the IC turns off an internal N-channel MOSFET to remove
power from the charging system to the battery. The IC also
monitors its own internal temperature and turns off the
N-channel MOSFET when the temperature exceeds +150°C.
Together with the battery charger IC and the protection module
in a battery pack, the charging system using the ISL9211B has
triple-level protection and is two-fault tolerant.
• 24V Max Input Voltage
The IC is designed to turn on the internal NFET slowly, to avoid
in-rush current at power-up. It turns off the NFET quickly when
the input is overvoltage, to remove power before damage
occurs. The ISL9211B has a logic flag output to indicate a fault
condition. The enable input allows the system to cut off the
input power, if needed.

Theory of Operation
The ISL9211B is an integrated circuit (IC) optimized to provide
redundant safety protection to a Li-ion battery against charging
system failures. The IC monitors input voltage, battery voltage,
and charge current. When any of these parameters exceeds its
limit, the IC turns off an internal N-channel MOSFET to remove
power from the charging system. The IC also monitors its own
internal temperature and turns off the N-channel MOSFET when
temperature exceeds +150°C. Together with the battery charger
IC and the protection module in a battery pack, the charging
system has triple-level protection against overcharging the Li-ion
battery and is two-fault tolerant. The ISL9211B protects up to
26V input voltage.
Power-Up
The ISL9211B has a power-on reset (POR) threshold of 2.47V
(max). Before the input voltage reaches the POR threshold, the
internal power NFET is off. Approximately 10ms after the input
voltage exceeds the POR threshold, the IC resets itself and
begins soft-start. The 10ms delay allows any transients at the
input during a hot insertion of the power supply to settle down
before the IC starts to operate. The soft-start slowly turns on the
power NFET to reduce the inrush current as well as the input
voltage drop during the transition. Figure 2 shows the power-up
sequence.
Input Overvoltage Protection (OVP)
The input voltage is monitored by the comparator, CP1, as shown
in the “Block Diagram” on page 2. CP1 has an accurate
reference of 1.2V from the bandgap reference. The OVP
threshold is set by the resistive divider consisting of R1 and R2.
When the input voltage exceeds the threshold, CP1 outputs a
logic signal to turn off the power NFET within 1µs (see Figure 3).
This prevents high input voltage from damaging the electronics
in a handheld system. Hysteresis for the input OVP threshold is
given in the “Electrical Specifications” table on page 4. When the
input overvoltage condition is removed, the ISL9211B re-enables
the output by running through soft-start, as shown in Figure 5.
Because of the 10ms delay before soft-start, the output is never
Submit Document Feedback
8
enabled if the input rises above the OVP threshold quickly, as
shown in Figure 6.
Battery Overvoltage Protection
Battery voltage OVP is realized with the VB pin. The comparator,
CP3, shown in the “Block Diagram” on page 2, monitors the VB
pin and issues an overvoltage signal when battery voltage
exceeds the 4.34V battery OVP threshold. The threshold has
30mV built-in hysteresis. The comparator, CP3, has a built-in
180µs blanking time to prevent any transient voltage from
triggering OVP. If the OVP situation still exists after the blanking
time, the power NFET is turned off. The control logic contains a
4-bit binary counter so that, if the battery overvoltage event
occurs 16 times, the power NFET is turned off permanently, as
shown in Figure 7. Recycling the input power resets the counter
and restarts the ISL9211B.
The resistor, RVB, between the VB pin and the battery, as shown
in “TYPICAL APPLICATION CIRCUIT” on page 1, is an important
component. This resistor provides a current limit in case the VB
pin is shorted to the input voltage under a failure mode. VB pin
leakage current under normal operation is negligible, which
allows a resistance of 200kΩ to 1MΩ to be used.
Overcurrent Protection (OCP)
To prevent charging the battery with excessive current, the
current in the power NFET is limited. Current is sensed using the
voltage drop across the power FET after it is turned on. The
reference for the OCP is generated using a sensing FET, Q2
(mirror to Q1), as shown in the “Block Diagram” on page 2. The
current in the sensing FET is forced to match the value
programmed by the ILIM pin. The OCP threshold can be set with
the resistor, RLIM, as shown in Table 1.
The size of the power FET, Q1, is 31,250 times the size of the
sensing FET. Therefore, when the current in the power FET is
31,250 times the current in the sensing FET, the drain voltage of
the power FET falls below that of the sensing FET. The
comparator, CP2, then outputs a signal to turn off the power FET.
When an OCP condition is encountered, the power FET is turned
off immediately and then attempts to restart. If the condition

Internal Over-Temperature Protection
The ISL9211B monitors its own internal temperature to prevent
thermal failures. When the internal temperature reaches
+150°C, the IC turns off the N-channel power MOSFET. The IC
does not resume operation until the internal temperature drops
below +110°C.
Fault Indication Output
The FAULT pin is an open-drain output that indicates a LOW
signal when any of the three fault events occurs. This provides a
signal to the microprocessor to take further action to enhance
the safety of the charging system.
Applications Information
The ISL9211B is designed to meet the “Lithium-Safe” criteria
when operating together with a qualified Li-ion battery charger.
The “Lithium-Safe” criteria require the charger output to fall
within the green region shown in Figure 15 under normal
operating conditions and not to fall within the red region when
there is a single fault in the charging system. Taking into account
the safety circuit in a Li-ion battery pack, the charging system is
allowed to have two faults without creating hazardous conditions
for the battery cell. The output of a Li-ion charger such as the
ISL6292C has a typical I-V curve (shown by the blue lines in
Figure 15) under normal operation (shown by the green region).
The function of the ISL9211B is to add a redundant protection
layer such that, under any single fault condition, the charging
system output does not exceed the I-V limits (shown by the red
lines). As Figure 15 shows, a charging system that includes the
ISL9211B and the ISL6292C chip set can easily meet the
“Lithium-Safe” test criteria.
The ISL9211B is a simple device that requires only three external
components, in addition to the ISL6292 charger circuit, to meet
the “Lithium-Safe” criteria (see “TYPICAL APPLICATION CIRCUIT”
on page 1. The selection of the current limit resistor, RLIM, is

RVB Selection
RVB prevents a large current from the VB pin to the battery
terminal, in case the ISL9211B fails. The recommended value is
between 200kΩ and 1MΩ. With 200kΩ resistance, the
worst-case current flowing from the VB pin to the charger output
is shown in Equation 1, assuming VB pin voltage is 24V under
failure mode and battery voltage is 4.2V.
 24V – 4.2V    200k  = 99A
(EQ. 1)
Such a small current can easily be absorbed by the bias current
of other components in a handheld system. Increasing the RVB
value reduces the worst-case current but at the same time
increases the error for the 4.34V battery OVP threshold.
The battery OVP threshold error is the original accuracy at the VB
pin given in the “Electrical Specifications” table on page 4, plus
the voltage built across RVB by the VB pin leakage current. The
VB pin leakage current is less than 20nA, as given in the
“Electrical Specifications” table on page 4. With a 200kΩ
resistor, the worst-case additional error is 4mV; with a 1MΩ
resistor, the worst-case additional error is 20mV.
Capacitor Selection
The input capacitor (C1 in the “TYPICAL APPLICATION CIRCUIT”
on page 1) is for decoupling. A higher value reduces the voltage
drop or the over-shoot during transients.
Two scenarios can cause input voltage over-shoot. The first one is
when the AC adapter is inserted live (hot insertion). The second
one is when the current in the power NFET of the ISL9211B has a
step-down change. Figure 16 shows an equivalent circuit for the
ISL9211B input. The cable between the AC/DC converter output
and the handheld system input has a parasitic inductor. The
parasitic resistor is the sum of various components, such as the
cable, the adapter output capacitor ESR, the connector contact
resistance, and so on.

HANDHELD SYSTEM
FIGURE 16. EQUIVALENT CIRCUIT FOR ISL9211B INPUT
During the load current step-down transient, the energy stored in
the parasitic inductor is used to charge the input decoupling
capacitor, C2. The ISL9211B is designed to turn off the power
NFET slowly during an OCP and battery OVP event. Because of
this design, the input over-shoot during these events is not
significant. During an input OVP, however, the NFET is turned in
less than 1µs and can lead to significant over-shoot. Higher
capacitance reduces the over-shoot.
The output of the ISL9211B and the input of the charging circuit
typically share one decoupling capacitor. Selection of that
capacitor is determined mainly by the requirements of the
charging circuit. When using the ISL6292 family of chargers, a
1µF, 6.3V, X5R capacitor is recommended.
Layout Recommendation
The ISL9211B uses a thermally enhanced TDFN package with an
exposed thermal pad at the bottom of the package. The layout
should include as much copper as possible beneath the exposed
pad on the component layer to improve thermal performance.
The exposed pad under the package should be connected to the
ground plane electrically as well as thermally. The vias should be
about 0.3mm to 0.33mm in diameter. Use as many vias as will fit
in the thermal pad area.
Over-shoot caused by a hot insertion is not very dependent on the
decoupling capacitance value, especially when ceramic type
capacitors are used for decoupling. In theory, over-shoot can rise
up to twice the DC output voltage of the AC adapter. Actual peak
voltage is dependent on the damping factor that is mainly
determined by parasitic resistance (R in Figure 16).
