Notice On Data Sheet Designations
Cypress Semiconductor Corp. issues data sheets with Advance Information or Preliminary designations to
advise readers of product information or intended specifications throughout the product life cycle, including
development, qualification, initial production, and full production. In all cases, however, readers are
encouraged to verify that they have the latest information before finalizing their design. The following
descriptions of Cypress data sheet designations are presented here to highlight their presence and
definitions.
Advance Information
The Advance Information designation indicates that Cypress Semiconductor Corp. is developing one or
more specific products, but has not committed any design to production. Information presented in a
document with this designation is likely to change, and in some cases, development on the product may
discontinue. Cypress Semiconductor Corp. therefore places the following conditions upon Advance
Information content:
“This document contains information on one or more products under development at Cypress
Semiconductor Corp. The information is intended to help you evaluate this product. Do not design in
this product without contacting the factory. Cypress Semiconductor Corp. reserves the right to
change or discontinue work on this proposed product without notice.”
Preliminary
The Preliminary designation indicates that the product development has progressed such that a commitment
to production has taken place. This designation covers several aspects of the product life cycle, including
product qualification, initial production, and the subsequent phases in the manufacturing process that occur
before full production is achieved. Changes to the technical specifications presented in a Preliminary
document should be expected while keeping these aspects of production under consideration. Cypress
places the following conditions upon Preliminary content:
“This document states the current technical specifications regarding the Cypress product(s)
described herein. The Preliminary status of this document indicates that product qualification has
been completed, and that initial production has begun. Due to the phases of the manufacturing
process that require maintaining efficiency and quality, this document may be revised by subsequent
versions or modifications due to changes in technical specifications.”
Combination
Some data sheets contain a combination of products with different designations (Advance Information,
Preliminary, or Full Production). This type of document distinguishes these products and their designations
wherever necessary, typically on the first page, the ordering information page, and pages with the DC
Characteristics table and the AC Erase and Program table (in the table notes). The disclaimer on the first
page refers the reader to the notice on this page.
Full Production (No Designation on Document)
When a product has been in production for a period of time such that no changes or only nominal changes
are expected, the Preliminary designation is removed from the data sheet. Nominal changes may include
those affecting the number of ordering part numbers available, such as the addition or deletion of a speed
option, temperature range, package type, or VIO range. Changes may also include those needed to clarify a
description or to correct a typographical error or incorrect specification. Cypress Semiconductor Corp.
applies the following conditions to documents in this category:
“This document states the current technical specifications regarding the Cypress product(s)
described herein. Cypress Semiconductor Corp. deems the products to have been in sufficient
production volume such that subsequent versions of this document are not expected to change.
However, typographical or specification corrections, or modifications to the valid combinations
offered may occur.”
Questions regarding these document designations may be directed to your local sales office.

10. Description of Functions
10.1 Dimming Function
S6AL211 series are integrated with 4channels LED-lighting dimming circuits.
The change in the brightness of the LED, the combination of current dimming (i.e. change the LED current)
and the PWM dimming (i.e. change the turning on and off time of the LED) is possible. As a result, you can
choose the best dimming type for your application.
Dimming Type B:
It is a dimming method that controls the LED current by brightness setting data. By the LED continuously
lighted, flicker-free application can be realized. In addition, FET of the PWM dimming is not required for
reduce the BOM.
Dimming Type C:
By adding the PWM dimming to the current dimming, providing deep dimming that expands the dynamic
range of brightness. It can output a brightness of less than 1% by the PWM dimming.

10.2 Constant Current Control
S6AL211 series are integrated with 4ch. constant current control circuit. It based on the step-down (Buck)
DC / DC converter.
DC / DC converter generates VOUT voltage from VIN voltage by controlling the ON / OFF duty of external
switching FET (Pch.) which connected to DRV_n terminal.
The LED current (ILED) of lighting LED depend on the VF-IF characteristics of the LED. The ILED value is
converted into voltage by the detection resistor Rs, and is feedback to the control circuit from CS_n terminal.
A control circuit compares and controls the ILED current coincided with the target current value by changing
output voltage VOUT.
In the case of only current control (Dimming type B), external PWM FET (Nch.) is not necessary.

10.5 Protection Function
S6AL211 series are integrated with various protection functions. Protection function has 10 protection
functions and 4 protection states.
When the protection factor (i.e. Measurement target in for protection) in each protection function exceeds
protection conditions (i.e. Detection value and number of detected), it moves to a protection mode. In the
protection mode, function of reduce the lighting or lights off, and function of IC operation stop are performed.
As a result, the LED circuit and the power supply circuit are protected safely.
<Note>
−
10.5.1
In addition, we have implemented safety considerations by being integrated with various protection
functions. However, to prevent smoke or ignition if circuit is failure such as broken the external FET
or the IC, should mount the protection circuit or fuse at the power supply circuit.
Protection States
S6AL211 series have the following 4 protection states.
Dimming Protection, Lights out Protection-1, Lights out Protection-2 and Lights out Protection-3
Reducing LED output current and Keeping lighting-ON to eliminate the protection
conditions
Dimming Protection : Lights down operation which reduce the LED output current of 10% from 100%
brightness
− “Protection release wait time” is assigned by the Protection States. When during “Protection release
wait time” ignores request of brightness increase from communication interfaces (UART and sensor
input ) (Request of brightness reduce or lights-off are enabled). (*1)
− If the protection condition is detected again during “Protection release wait time”, adds the Lights down
operation. It reduces the LED output current of 10% from 100% brightness. In addition, it resets the
“Protection release wait time”.
− If lights out ( LED output current is zero) as a result of the Dimming Protection, IC moves to the Lights
out Protection-2 state.
− When the protection condition is not detected again during “Protection release wait time”, IC moves to
the Normal state. And reduced brightness by the Lights down operation is maintained until received
the new brightness from communication interface.
Lighting-OFF, if the circuit behavior is abnormal or the protection condition is not
eliminated by Dimming Protection
 Lights out Protection-1: Lights out operation
− After Lights out and “Restart wait time”, IC is initialized for return from the protection state and
restarted lighting operation (auto restart). (*2)
− When IC receives communication from communication interface (DALI and UART ) during “Restart
wait time”, IC is initialized and restarted immediately. (*2)
 Lights out Protection-2: Lights out operation
− It does not restart automatically. (latch off)
− When IC receives communication from communication interface (DALI and UART), IC is initialized and
restarted. (*2)
 Lights out Protection-3: Lights out and Shutdown of IC operation
− IC maintains the protection (Shutdown) state until eliminated of the protection conditions.
− To avoid the failure operation, IC stops functions other than protection and moves to the shutdown.
− When eliminated of the protection conditions, IC is initialized and restarted (auto restart). (*2)

Function of Protection Status Output
S6AL211 series has a feedback output pin (PCNT) for outputting to an external IC. It informs moved to the
protection states (Lights out Protection-1, -2 and -3) which has safety problem.
It can be used as a signal which informs the failure lighting to the MCU in the lighting system.

10.6 Standby Function
S6AL211 series are integrated with the standby function.
It reduces the power consumption of the IC by stops the functions other than minimum necessary functions.
Move to the Standby State
When the all channels brightness is set to the Lights out (0% brightness), the LED current flow turns to 0A.
Then IC moves to the Standby state after the “Standby transition wait time”.
When IC receives communication from communication interface or input from sensors during the “Standby
transition wait time”, IC returns to the Normal Dimming Operation.
And, IC does not move to the Standby state from Lights out by protection function.
Standby State
It is a state of low power consumption. IC stops functions other than the communication interface and sensor
inputs for acceptance of return to the Normal Dimming Operation.
3V LDO continues an output.
Return to the Normal State from Standby State
When IC receives communication from communication interface or sensor inputs, IC returns to the Normal
Dimming Operation.

10.7 Power-on and Power-off
When power is supplied to the S6AL211 series, the constant current control circuit outputs a stable output
current to within 0.3s after reaching the recommended operating voltage.
(When don't use the Fade function and DALI, Not include 0.6s of waiting time for the Power Level
command.)
After the Power-on, the brightness becomes to the set value "POWER ON LEVEL". (Please refer to the
hardware manual of each IC: S6AL211A21, S6AL211A31 and S6AL211A94 for "POWER ON LEVEL".)
If the power supply is stopped without Lights out setting, IC stops switching operation of the constant current
control circuit safely by functions of the Input Low Voltage Protection and the Input Under Voltage shutdown.

10.8 LDO
S6AL211 series are integrated a 3V LDO regulator for supplying the power to the peripheral circuits. It can
be used, for example, the power supply of the sensors (temperature sensor, ambient light sensor, human
2
motion detect sensor), PullUp power of I C Bus and the power supply of the communication module.
Therefore it reduces the BOM cost, reduces board mounting area and realizes the other power ICs
unnecessary.
LDO continues an output in standby state.
VO pin must be connected to a bypass capacitor.
If the output current of the LDO becomes over current, reduce the output voltage and current by the
conventional fold-back current limiting characteristic.

13. Usage Precautions
Do not configure the IC over the maximum ratings.
If the IC is used over the maximum ratings, the LSI may be permanently damaged.
It is preferable for the device to normally operate within the recommended usage conditions. Usage outside
of these conditions can have an adverse effect on the reliability of the LSI.
Use the device within the recommended operating conditions.
The recommended values guarantee the normal LSI operation under the recommended operating
conditions.
The electrical ratings are guaranteed when the device is used within the recommended operating conditions
and under the conditions stated for each item.
Printed circuit board ground lines should be set up with consideration for common
impedance.
Take appropriate measures against static electricity.
 Containers for semiconductor materials should have anti-static protection or be made of conductive
material.
 After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.
 Work platforms, tools, and instruments should be properly grounded.
 Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ in serial between body and
ground.
Do not apply negative voltages.
The use of negative voltages below - 0.3V may make the parasitic transistor activated to the LSI, and can
cause malfunctions.
