µP Controlled Battery Charger
for 1-Cell Li-ion or 1-Cell to 3-Cell NiCd/NiMH Batteries
DESCRIPTION
FEATURES
Si9731 is a chemistry independent battery charger designed
to pulse charge 1-cell to 3-cell NiCd/NiMH or 1-cell Li-ion
batteries. Battery charging is accomplished under direct
control from the system processor. An internal low RDS(on)
MOSFET can be pulsed on and off at varying duty cycle by
the system processor to pulse charge the battery at high
charge current while minimizing heat dissipation. Provision is
also made to trickle charge a discharged battery until the
battery is charged to a high enough voltage to wake up the
processor so that the processor can take control of the
charging process. For charging Li-ion batteries, Si9731
includes a precision voltage reference and an error amplifier
for constant voltage (CV) charge mode. The Si9731 is
available in lead (Pb)-free TSSOP-16 package and is
classified over the industrial temperature range (- 40 °C to
+ 85 °C).

Si9731
Vishay Siliconix
DETAIL OPERATIONAL DESCRIPTION
Si9731 is a chemistry independent battery charger designed
for use with a system processor. For example, Si9731 can be
integrated within a cellular phone whereby the fast charge
and trickle (slow) charge modes can be software controlled
by the DSP. The device is designed to charge 1-cell Li-ion or
1-cell to 3-cell NiCd/NiMH batteries. A regulated or
unregulated external dc power source such as a wall adapter
rated at typically 4.5 V to 12 V is connected to Si9731’s
VCHARGER input pin. Note that a typical low cost wall adaptor
is comprised of a transformer, bridge rectifier and a reservoir
capacitor. The wall adaptor’s output voltage decreases
linearly with increase in output current. When Si9731 is fast
charging the battery, the wall adaptor’s output voltage tracks
the battery voltage plus the voltage drop across Q1 (charging
current times MOSFET Q1’s RDS(on), see Figure 1). The key
features of Si9731 are described below.
Since the under voltage lock out (UVLO) point of Si9731 is
2.6 V (typical), it is essential to keep the charger voltage
above this level under all conditions, especially for fast
charging of single cell NiCd/NiMH. One simple solution is
adding a external resistor between VBAT+ pin and the battery,
which creates extra voltage drop to elevate the charger
voltage. The value of the resistor is affected by the output
V-I characteristic of the ac charger.
Trickle Charge
The charge path is via N-Channel MOSFETs Q1 or Q2 (see
applications circuit of Figure 1). Si9731 defaults to trickle
(slow) charge mode if the battery voltage is too low to power
the main processor. With the main processor unable to drive
the
MAINCHARGEEN
pin
as
well
as
the
TRICKLECHARGEEN pins, Q1 is turned "OFF" preventing
fast charging. Meanwhile N-Channel MOSFET Q2 turns
"ON" and establishes a trickle charge path from the external
power source VCHARGER to the battery. The trickle charge
current is set by an external current limiting resistor, Rext, and
is approximately ITRICKLE = (VCHARGER - VBAT+)/Rext. Once
the battery voltage charges up to minimum battery operating
voltage 3.24 V, the internal latch is triggered and the
CHARGERPOWER_ON output changes state to wake up
the processor. The processor is now able to disable trickle
charge mode by taking the TRICKLECHARGEEN pin high
while taking control of fast charging via the
MAINCHARGEEN pin.
www.vishay.com

Fast Charge
Fast charging is accomplished by the low "ON" resistance
MOSFET, Q1. The application microprocessor is able to
"Pulse Charge" the battery via the MAINCHARGEREN
control input of Si9731. The processor monitors the battery
voltage via the system A/D converter and varies the pulse
charging duty cycle accordingly to maintain fast charging.
Note that even though charging current may be sufficiently
high, pulse charging with short "ON" time and long "OFF"
time ensures that heat generation due to thermal heating is
reduced.
In the case of NiCd or NiMH batteries, one of several charge
termination schemes may be used to terminate charge. For
example, the processor may disable fast charging by
sensing ΔV or dV/dt at the VBAT+ output or by monitoring the
temperature differential ΔT of the battery. Following fast
charge, trickle charge may be enabled to "top off" the battery.
When charging a 1-cell Li-ion battery, fast charging will
operate in two modes, constant current mode followed by
constant voltage mode. In the constant current mode, a
discharged Li-ion battery is charged with constant current
available from the external dc source. The MOSFET pass
transistor (Q1) may be pulsed "ON" and "OFF" at varying
duty cycle by the control signal present at the
MAINCHARGEEN input pin. Once the battery voltage
reaches it’s termination voltage of 4.1 V or 4.2 V (depending
on the connection of the 4.1 VTAP), Si9731 may be placed in
the "Constant Voltage" charging mode by taking the
CVMODE pin high. Taking CVMODE pin high disables trickle
charging and enables the internal battery voltage divider by
turning ON Q5. Then the error amplifier will compare divided
VBAT+ voltage against an internal precision 1.3 V bandgap
reference voltage (see Figure 1). The output of the error
amplifier drives the pass transistor Q1 to maintain VBAT+ at
the regulated termination voltage. This operation is same as
a linear regulator.
True Load Disconnect
Both the fast charge FET (Q1 in Figure 1) and trickle charge
FET (Q2 in Figure 1) incorporate a floating body diode. In
their "OFF" state both FETs block current bidirectionally.
Note that because of the reverse blocking switches, a
Schottky diode in series with the external VCHARGER power
supply is not required.

Si9731
Vishay Siliconix
DETAIL OPERATIONAL DESCRIPTION
4.1 VTAP
Thermal Shutdown
The Si9731’s internal feedback resistors are set to provide
4.2 V charge termination at VBAT+ output if the 4.1 VTAP is left
open circuit. Connecting the 4.1 VTAP to VBAT+ configures
Si9731 for 4.1 V charge termination at VBAT+. This feature
allows Si9731 to accommodate Li-ion batteries requiring
4.1 V or 4.2 V charge termination. Caution: the 4.1 VTAP
should not be connected to ground or any other voltage
source as this will cause the Si9731 to operate open loop and
can result in over charging the battery!
Si9731 also includes a thermal protection circuit that
suspends charging through Q1 and Q2 when die
temperature exceeds 130 °C due to overheating. Once the
die temperature cools to below 120 °C, the charging will
resume.
Feedback Disconnect Switch
The Si9731 includes a feedback disconnect switch (Q5 in
Figure 1) connected in series with the device’s internal
feedback resistor string. The 42 kΩ feedback resistor string
is connected to ground when both the internal "OK to
Charge" signal and the CVMODE pin are at logic high,
providing feedback voltage to Si9731’s error amplifier. This
action helps prevent the Si9731 from discharging the battery.
CHARGERPRESENT and CHARGERPOWERON
Shutdown
Si9731 can be completely turned off by applying 0.4 V or less
to the device’s ON/OFF pin. In shutdown mode, Si9731
draws less than 1 µA quiescent current with charger voltage
below UVLO, and draws 500 µA when charger voltage is
above UVLO. The device is enabled by applying 1.5 V to
12 V at the ON/OFF pin. In applications where the device will
always remain enabled, the ON/OFF pin may be connected
to the VCHARGER pin. Si9731’s shutdown circuitry includes
hysteresis, as such the device will operate properly even if a
slow moving signal is applied to the ON/OFF pin. When the
device is enabled, the battery voltage sense circuitry draws
approximately 25 µA from VBAT.
OK to Charge (OTC)
CHARGERPRESENT and CHARGERPOWERON are open
drain outputs, each requiring an external pull-up resistor.

CHARGERPOWERON
CHARGERPOWERONIN Pin is high, charger voltage is not
in UVLO and the battery voltage has increased to above
3.24 V, turning on the system power supply since the battery
has been charged up to minimum operating voltage.
Input Over-Voltage Detector
The external dc source connected to the VCHARGER pin
should be at 12 V or less. In the unlikely event that the
voltage at VCHARGER pin is at or above 12.8 V (typical),
Si9731’s internal over voltage detector will turn off MOSFETs
Q1, Q2, and Q5 and disable charging.
Si9731 also includes an internal signal that enables both
trickle charge mode and fast charge mode operations, the
"OK to Charge" (or OTC) signal. The OTC signal is at logic
high if all of the following are satisfied:
1. Battery voltage is below 5 V
2. Charger voltage is greater than 2.6 V but below 12.8 V
3. VCHARGER > VBAT + 40 mV when MAINCHARGEEN =
Low
VCHARGER > VBAT - 40 mV when MAINCHARGEEN =
High
4. ON/OFF pin is at logic high.
In order to charge the battery in any manner, the OTC signal
has to be high.
