Functional Description
Each voltages written in following are set in standard application circuit.
1. Adapter Constant Voltage Control
VDET pin supplies this block with voltage to control voltages of both adapter and protection during charge. Control
reference voltage, applied by REFOUT pin, is constant.
Output voltage is generated from dividing the adapter voltage by external two resistors connected to VDET pin and the
modification of the dividing ratio of these resistors by CHG pin changes the voltage of Adapter/Charge.
2. Charge Constant Current Control Block
IDET pin supplies this block with voltage to control constant current during charge and is controlled directly by the
voltage of 0.1 Ω resistance, connected to low side, for the current detection. Control referential voltage is set by ratio
between external two resistors connected to REFOUT pin. Battery temperature detection control performs switching
quick and trickle by selecting ADJ pin as follows:
Quick charge: ADJ1 pin
Trickle charge: ADJ2 pin
Adapter constant voltage control, written in 1 clause, is capable of invalidating this control.
3. Charge Constant Voltage Control Block
VBIN pin supplies this block with voltage to control constant voltage during charging. Output voltage of VBOUT pin,
gained differentially from battery voltage, supplies to VBIN pin. Control referential voltage, applied from REFOUT pin,
is constant.
4. Charge SW Driving Circuit Control Block
This block controls SW pin, driving transistor for charging SW.
Charge off: SW = OPEN
Charge on: SW = L
5. Battery Voltage Differential Gain Block
Battery voltage input from B+/B– pin directly and outputs to VBOUT pin after differential gained. The gain of
amplifier is 1/3.
VBOUT = 1 / 3 (VB+ – VB–)
Input of OP-amp for differential gain or feedback resistance depends on external circuit element.
REJ03F0240-0200 Rev.2.00 Jun 16, 2008
Page 6 of 21
M62241FP
6. Output Current & Voltage Amplifier Block
The voltage between GND and IDET pin is available to several detector after amplified. The gain of this amplifier is 13.
The gain range: 0 to 2 A (Input voltage 0 to 0.2 V) → 0.2 to 2.6 V
7. Detection of Battery Connection/Battery Temperature
This block detects the battery connection and the battery temperature by the input voltage dividing between thermistor
inside battery package and resistances outside REFIN pin.
Each referential voltage for detection is set by dividing REFOUT pin voltage by in side resistances.
The dividing circuits are grounded to THS pin connected directly to – terminal of battery to prevent input voltage of TH
pin from changing by the current of external circuit.
1. Battery connection detection
The battery connection is recognized in case the resistance of the thermistor connected to TH pin is less than the
following:
Thermistor resistance (Rth): less than approximately 100 kΩ
Detecting timing is as follows:
60 ms × 2 times = 120 ms (foc = 3.41 kHz)
2. Battery temperature detection
This block controls to switch charging after detecting the battery temperature by the dividing ratio between
resistance pulled up and thermistors.
Detecting timing is as follows:
60 ms × 2 times = 120 ms (foc = 3.41 kHz)
For further details, read the 20 clause.
8. Over Discharge Detection Block
In case the voltage majored before starting to charge is less than the detection voltage, the over discharge mode is taken
over before waiting. It continues to wait until the battery charges from external circuit and the charge mode is taken
over after the voltage becomes more than the detection voltage. The differential gain output voltage of the battery is
majored at this block.
The referential voltage for detecting is set by the dividing ratio between resistors connected to the REFOUT pin.
The over discharge detection voltage (V Blow) is 4.0 V.
This detection is disregarded during charging.
The detection timing is as follows:
300 ms × 4 times = 1.2 s (foc = 3.41 kHz)
9. Over Voltage Detection Block
NG mode is taken over, in case the voltage majored before starting to charge is more than the following voltage. The
referential voltage for detecting is REFOUT output voltage.
The over detection voltage (Vbhigh) is VREFOUT.
This detection is disregarded during charging.
The detection timing is as follows:
300 ms × 4 times = 1.2 s (foc = 3.41 kHz)
REJ03F0240-0200 Rev.2.00 Jun 16, 2008
Page 7 of 21
M62241FP
10. The Charge Completion Detection Block
The charge completion mode is taken over in case the charge current in charge mode is less than the detection current.
This detection depends on the gained current output.
The referential voltage for detection is set by the dividing ratio between resistors connected to ADJ3 pin. This detection
is discharged except during charging.
The detection timings is as follows:
600 ms × 8 times = 4.8 s (foc = 3.41 kHz)
11. The Adapter Over Current Mode
The unusual mode is taken over in case the current majored in the adapter mode is less than the detection current.
The referential voltage for the detection is set by the dividing ratio between the resistors connected to ADJ0 pin.
The detection is disregarded except in adapter mode.
Detection timing is as follows:
3.0 s × 4 times = 12 s (foc = 3.41 kHz)
12. LED Driving Block
This block controls LED driving pin by each mode.
Adapter mode:
No battery connection mode:
Charge mode:
off

Unusual mode:
off
Note: LED on/off timing is 1/1.5 Hz (0.9 s on/0.6 s off) respectively.
13. The Regulated Referential Power Supply Block
The charge of output REFOUT pin voltage depends on inside band gap voltage as the reference and the gained voltage
of the changeable resistance connected to REFOUT pin.
This block uses REFOUT output voltage as reference and controls the charge constant voltage and every reference both
inside and outside.
REFOUT typical voltage: 1/3 of the battery charge constant voltage
14. Adapter Detection Block
The adapter connection input switches the mode as follows:
OPEN (H) detection: Adapter connection
GND (L) detection: No adapter connection
The detection timing is as follows:
12 ms × 2 times = 24 ms (foc = 3.41 kHz)
REJ03F0240-0200 Rev.2.00 Jun 16, 2008
Page 8 of 21
M62241FP
15. Adapter Mode Control Block
The detection of adapter connection changes all modes except unusual mode into adapter mode.
The next mode after adapter mode depends on the previous mode.
Previous mode
→ Next mode
No connection
→ No connection
Charge
→ Charge (after initialization)
Over discharge
→ Charge (after initialization)
Temperature protection → Charge (after initialization)
Charge completion
→ Charge completion
Charge NG
→ Charge NG
Note: The detection of no battery connecting during adapter mode disregards the previous mode and takes over no
battery mode.
16. PC Driving Block
The control to the PC pin, for driving photo coupler, depends on each control of adapter constant voltage, charge
constant current and charge constant voltage.
Vcc side: Photo coupler off, output voltage rising
GND side: Photo coupler on, output voltage falling
17. PC Short Control Block
The unusual mode is taken over in case the over current is detected during the adapter mode.
This block is capable of fixing PC output into Vcc side and shutting down the primary power supply current. All input
and detection are disregarded in the unusual mode. Only reset is capable of returning from unusual mode.
18. AC Check Detection Block
AC power off is recognized and adapter mode is taken over, in case the PC pin voltage continues more than the
following voltage in certain period:
AC check voltage (Vacchk: Vcc – 0.8 V)
The detection timing is as follows:
60 ms × 16 times = 960 ms (foc = 3.41 kHz)
19. Timer Block
(1) Waiting timer after battery connection
This block pauses for following period from the battery connection detection to starting charge, so that every input
is decided.
Waiting time: approximately 3.2 s (foc = 3.41 kHz)

(2) Display timer
Counting the following time after starting to charge switches display from on/off to on.
Display timer: 30 m (foc = 3.41 kHz)
In trickle charge mode, this timer pauses to count. This timer resets counting to initialize before charge restarting, in
case the charge as counting or pausing stops because of the charge to the adapter mode or the temperature protection
mode.

4. All information included in this document such as product data, diagrams, charts, programs, algorithms, and application circuit examples, is current as of the date this
document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas products listed in this document,
please confirm the latest product information with a Renesas sales office. Also, please pay regular and careful attention to additional and different information to be
disclosed by Renesas such as that disclosed through our website. (http://www.renesas.com )
5. Renesas has used reasonable care in compiling the information included in this document, but Renesas assumes no liability whatsoever for any damages incurred as a
result of errors or omissions in the information included in this document.

application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products.
7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
(1) artificial life support devices or systems
(2) surgical implantations
(3) healthcare intervention (e.g., excision, administration of medication, etc.)
(4) any other purposes that pose a direct threat to human life
Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing
