The device includes four sub-strings of three seriesconnected integrated switches for bypassing
individual LEDs. The individual sub-strings allow the
device to accept either single or multiple current
sources. It also allows paralleling up to four switches
for bypassing high current LEDs.
A master microcontroller is used to control and
manage the TPS92662-Q1 devices via a multi-drop
universal asynchronous receiver transmitter (UART)
serial interface. The serial interface supports the use
of CAN transceivers for a more robust physical layer.
The I2C communication interface can be used to read
from and write to an external EEPROM that can store
system calibration data.
An on-board 8-bit ADC with two multiplexed inputs
can be used for system temperature compensation
and used to measure a binning value which allows for
LED binning and coding.
The internal charge pump rail supplies the gate drive
voltage for the LED bypass switches. The low onresistance (RDS(on)) of the bypass switch minimizes
conduction loss and power dissipation.
The phase shift and pulse width for each individual
LED in the string are programmable. The device uses
an internal register to adjust the PWM frequency.
Multiple devices can be synchronized. The switch
transitions during PWM dimming operation have a
programmable slew rate to mitigate EMI concerns.
The device features open LED protection with
programmable threshold. The serial interface reports
open LED or short LED faults.

5.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.
