The following describes the functions of the primary module.
Item Description
Detection of landing Monitors intermittently to check whether the secondary module is placed on the top
of the primary module.
Fig. 3 shows the timing of the landing detection.
Detection removal Detects removal of the secondary module from the primary module, and enters
standby status.
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.
Detection of foreign metal
objects
Detection of foreign metal
objects
Monitors constantly to check whether any foreign metal object is inserted. If
detected, the module stops power transmission. 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. After the foreign metal object is removed, the module
resumes the initial state.
Detects the temperature of the center of coil, and when it becomes 70 °C or higher,
stops the power transmission. Power-on reset is required to resume the
transmission.
Installing thermistor between VREF and TDET as shown in the following diagram
enables you to detect temperature at any position.

Overvoltage protection Stops power supply to the subsequent overvoltage protection blocks immediately
when input voltage exceeds 6.2 ± 0.2V.When the input voltage returns to normal
level, the module resumes the initial state.
Detection of low voltage Stops power transmission when input voltage drops below 4.0 V during the
transmission. Power-on reset is required to resume the transmission.
Detection of low voltage Can display the state of primary module by connecting LED with the LEDA and
LEDK pins.
