IDTP9030
Product Datasheet
For maximum flexibility, the IDTP9030 tries to
communicate with the first address on the EEPROM at
100kHz.
attempted at the other addresses at 300kHz.
EEPROM
The IDTP9030 uses an external EEPROM which contains
either standard or custom TX firmware. The external
EEPROM memory chip is pre-programmed with a
standard start-up program that is automatically loaded
when 19V power is applied. The IDTP9030 uses I
address 0x52 to access the EEPROM. The IDTP9030
slave address is 0x39. The EEPROM can be
reprogrammed to suit the needs of a specific application
using the IDTP9030 software tool (see the IDTP9030-Qi
Demo Board User Manual for complete details). The IC
will look initially for an external EEPROM and use the
firmware built into the IC ROM only if no custom firmware
is found. A serial 8Kbyte (8Kx8 64Kbits) external
EEPROM is sufficient.
If the standard default/built-in firmware is not suitable for
the application, custom ROM options are possible. Please
contact IDT sales for more information. IDT will provide
the appropriate image in the format best suited to the
application.
Overview of Standard GPIO Usage
There are 7 GPIO’s on the IDTP9030 transmitter IC, of
which five are available for use as follows:

GPIO0: Red LED_A to indicate standby, fault
conditions, and FOD warnings; see table 7.
GPIO2: Temperature sensor input. Contact IDT
for a spreadsheet facilitating selection and use of
thermistors.
GPIO3: Green LED_B to indicate standby, power
transfer, and power complete. Table 7 lists how
the red and green LEDs can be used to display
information about the IDTP9030’s operating
modes.
about external resistors or internal pull up/down
options to select LED modes. Eight of the ten
LED modes (those associated with advanced
charging modes) are currently designated as
“Future” modes.
GPIO4: AC or DC buzzer (optional) with resistor
options for different buzzer configurations.

LED FUNCTIONS
Two GPIOs are used to drive LEDs which indicate,
through various on/off and illumination options, the state of
charging and some possible fault conditions.
A red L D indicates various Fault and FOD (“Foreign
Object Detection”) states.
Power Transfer and Charge Complete state information.
Upon power up, the two LEDs together may optionally
indicate the Standby State and remain in this state until
another of the defined Operational States occurs
As shown in Figure 16, one or two resistors configure the
defined LED option combinations. The DC voltage set in
this way is read one time during power-on to determine
the LED configuration. To avoid interfering with the LED
operation, the useful DC voltage range must be limited to
not greater than 1Vdc.
LED Pattern Operational Status Definitions:
Blink Slow: 1s ON, 1s OFF, repeat.
Blink Fast: 400ms ON, 800ms OFF, 400ms ON, 800ms
OFF, repeat.
The red FOD warning LED is synchronized with the
buzzer (if implemented) such that a 400ms tone
corresponds with the FOD red LED illumination and
800ms of silence corresponds with the LED being off.
During the 30s that the buzzer is off, the FOD LED must
continue to blink.
