parts. When you charge the battery, secure the service range and conditions recommended by the
battery manufacturer by detecting the battery condition (voltage, current, temperature) outside the
battery and build in protective circuits and control devices that operate when they detect a problem
to assure safety.
Embedding Conditions
2.3.8
This section describes examples of embedding the secondary module.
This product is designed on the premise of a metal shield being placed on the top of the secondary coil
unit.Place an aluminum, copper or another metal sheet with the size of approx. 35 × 35 mm on a position 0 to 5
mm away from the surface of the secondary coil unit. If the metal shield and the battery pack are not mounted,
the accuracy of the foreign metal detection function drops. Also, if a metallic housing or another metallic or
magnetic part is placed in the non-metal area of Figure 8, the leaked flux is absorbed by those metals and the
authentication range may become smaller. If the leaked flux is absorbed by the metal, the input current to the
primary module increases. Therefore, you can determine whether the leaked flux is absorbed by the metal or not
by simply measuring an increase of input current to the primary module without connecting the secondary
module to a load. The following shows the permissible value of increased input current to the primary module
that does not affect on the authentication range.
You can also check the authentication range using the special jig.
Permissible value of increased input current to the primary module caused by shield and other metal (*): 5 15mA

This chapter describes the overall specifications of the primary module (a module on the primary side) and
the secondary module (a module on the secondary side), consisting of the noncontact power transmission
modules.
The primary module drives intermittently while in standby state to keep detecting the landing of the
secondary module. If the primary module detects the secondary module, they execute reciprocal authentication
to ensure that they are the predefined combination permitted for the power transmission. If they pass the
authentication process, then the transmission can begin.
When the secondary module detects the fully charges state, it communicates with the primary module to enter
save mode, and shifts itself to save mode. If the secondary module maintains the landing state, the secondary
module detects that the battery voltage drops below the voltage defined to start recharging, and transmits the
information to the primary module to start recharging. If the recharging function is not used, the secondary
module continues to wait for the detection of removal.
During charging process, the secondary module reduces load periodically, and the primary module checks
whether the eddy-current loss occurs on the secondary side, caused by foreign metal objects. If any foreign
metal object is detected, the primary module stops power transmission.
Functional Description
2.4.2
The following describes the functions available when the primary module and the secondary module are
combined.
Item Description
Authentication Reciprocal process of authentication between the primary module and secondary
module. The process ensures that the power transmission is permitted only between
the predefined combination. The authentication procedure will be defined separately.
Transmission monitoring Monitors constantly to check whether any foreign metal object is inserted. If detected,
the power transmission is stopped. For this purpose, the secondary module reduces
load periodically, and the primary module checks whether the eddy-current loss occurs
on the secondary side, caused by foreign metal objects. However some metals objects
may not be detected depending on the method of embedding the module into chassis or
characteristics of the object. Therefore, this function is not assured to detect every bit of
the foreign objects.
Transmission monitoring
2.4.3
The noncontact power transmission module uses the following detection method assuming that metal objects
may erroneously be inserted into transmitter area during transmission. The secondary module enters unloaded
state at the timing shown in the following diagram, and flows load modulation current for a certain period of
time. The primary module monitors that load is changed between low and high state periodically. For example,
the primary module determines the eddy-current caused by foreign metal objects by detecting in low state the
higher load than standard value. When the primary module detects a foreign object, it stops transmission and
enters standby state.
The output current from the secondary module must be synchronized with the output from the ICUT pin of
secondary control IC (see the secondary circuit block diagram), and it must be above 5mA (inclusive) but below
40 mA (inclusive) in the low load state.

Safety against Foreign Metal Objects
2.4.5
As this system uses electromagnetic induction for power transmission, metal placed on the primary coil may
generate heat due to induction heating. The following design is incorporated into the modules against heat
generation of metal.
<Before ID authentication>
If a foreign metal object placed before authentication is detected, the system does not execute authentication
process and does not start power transmission.
<After ID authentication>
If a foreign metal object inserted after the authentication and during power transmission is detected by the
primary side, the system stops transmission and execute authentication process again. A metal object with
material and size that cannot be detected before and after the authentication must not rise its temperature higher
than 55 deg C under room temperature (25°C).
[Caution] The detecting ability may vary depending on the condition that the module is built on the product.
Make a full evaluation on it and check that there is nothing inconvenient before using. If it doesn’t
properly detect foreign matters, they may generate heat due to induction heating and reach
dangerous temperature.
[Caution] The detecting ability is not assured to detect all heat generating metals. Add safety circuits if
Output voltage on the secondary side depends on the position of primary coil unit and secondary coil unit.
