具有诊断功能的 TLC6C5816-Q1 电源逻辑 16 位移位寄存器 LED 驱动器
1 特性
TLC6C5816-Q1 器件是一个 16 位移位寄存器 LED 驱
动器,专门用于支持汽车 LED 应用。内置 LED 开路
和 LED 短路诊断机制提供增强的安全保护。该器件含
有 16 个带电源 DMOS 晶体管输出的通道。其中 8 个
通道配置了相应的寄存器,支持 LED 故障诊断,因此
该器件可以驱动 16 个不具有诊断功能的通道或 8 个具
有诊断功能的通道。诊断通道 DIAGn 必须连接到
DRAINn 才能实现 LED 诊断。命令错误故障表明通道
配置了 LED 诊断功能,但寄存器写入命令同时打开了
该通道。器件提供循环冗余校验,以验证移位寄存器中
的寄存器值。在读回模式中,该器件提供 6 位 CRC 提
醒。MCU 可以读回 CRC 提醒并检查该提醒是否正
确,以确定 MCU 与该器件之间的通信环路是否良好。

汽车应用中有各种 LED 指示器。某些 应用 (如混合
仪表组和电子旋钮式换挡器)具有安全要求,必须具有
LED 故障诊断功能;其他 应用 (如 HVAC 面板)仅
具有一个 LED 开关控制器,不要求具有 LED 诊断功
能。为了涵盖两种 应用,TLC6C5816-Q1 器件实现了
灵活的 LED 诊断功能。通过写入到寄存器,可以对输
出通道配置 LED 诊断 特性 或不配置 LED 诊断 特性。

7 Detailed Description
7.1 Overview
The TLC6C5816-Q1 device is a 16-bit shift-register LED driver designed to support automotive LED applications.
A built-in LED-open and LED-short diagnostic mechanism provides enhanced safety protection. The device
contains 16 channels with power DMOS transistor outputs, but 8 of the channels can instead be configured by
the corresponding DIAGn bits in the Configuration register to support LED fault diagnostics. The diagnostics
channels DIAGn must connect to DRAINn to realize LED diagnostics. A command error fault implies that a
channel is configured for LED diagnostics, but a register write command has turned on the channel at the same
time. The device provides a cyclic redundancy check to verify register values in the shift registers. In readback
mode, the device provides 6 bits of the CRC remainder. The MCU can read back the CRC remainder and check
if the remainder is correct. This checks whether the communication loop between MCU and device is good.

ZHCSH63B –OCTOBER 2017–REVISED JANUARY 2020
7.3.1 Device Enable (EN)
The TLC6C5816-Q1 device provides a low I(Q) mode. A high EN level shuts down the device, all the registers
reset, and the device enters standby mode. A low EN level enables the device, and all functions work normally.
7.3.2 Gated Output (Gx)
The device provides two active-low inputs to control gated outputs. G1 turns channels DRAIN0–DRAIN7 on and
off, and G2 turns channels DRAIN8–DRAIN15 on and off.
7.3.3 Register Clear (CLR)
The device provides a convenient function for clearing registers. A low CLR input level clears all internal registers
and all fault states. A high CLR level makes the device work normally.
7.3.4 Open-Drain Outputs and Flexible Diagnostics Channel
The device provides 16 output channels. All 16 channels have integrated low-side switches to drive external
loads such as LEDs independently. Eight channels have integrated voltage comparators dedicated for LED-open
and -short diagnostics as depicted in the following sections.
7.3.4.1 Configurable Outputs
The 16 channels are divided into eight pairs of outputs like DRAIN0, DRAIN1/DIAG0 as shown in 图 13. By
default, both outputs of this pair are open-drain outputs. Each of the pair is independent from the other.

图 13. Open-Drain Output and Flexible Diagnostics
By setting its bit in the configuration register to HIGH, the DRAIN1/DIAG0 output can be configured as
diagnostics channel DIAG0 for DRAIN0.
By setting the configuration register to LOW, DRAIN1/DIAG0 can be configured as the independent open-drain
output DRAIN1.
If DRAIN1/DIGA0 is configured as a diagnostics channel, when DRAIN0 is on, the DRAIN1/DIAG0 diagnostics
path monitors the voltage. When DRAIN0 is off, DRAIN1/DIAG0 is in the high-impedance state to avoid any
leakage current.

图 14. Diagnostics Configuration of Output Driver Pair
7.3.4.2 LED-Open Diagnostics
As depicted in Configurable Outputs, the DIAG0 channel monitors the anode voltage of the LED load of DRAIN0.
When the DRAIN0 channel turns on, DIAG0 compares the DRAIN0 voltage with internal threshold for LED-open
detection, V(OC_th). When DRAIN0 is on, and V(DIAG0) is continuously higher than V(OC_th) for tpd(deg_open), the device
asserts an LED-open fault, sets the corresponding bit in the fault table, and pulls ERR low.
An LED-open fault does not turn off the channel automatically in the LED-open state. Once the device detects an
open fault, it latches the fault status in the DIAGn_OPEN fault register. The fault register value only recovers to
normal when the LED fault disappears and the fault status is read back. Cycling Gx on and off does not clear the
fault.
7.3.4.3 LED-Short Diagnostics
As depicted in Configurable Outputs, the DIAG0 channel monitors the LED anode voltage of DRAIN0. When the
DRAIN0 channel is turned on, DIAG0 compares the DRAIN0 voltage with the internal threshold for LED short
detection, V(SC_th). When DRAIN0 is on and V(DIAG0) is continuously lower than V(SC_th) for tpd(deg_short), the device
asserts an LED-short fault, sets the corresponding bit in the fault flag table, and pulls ERR low.
The device does not turn off the channel automatically in LED-short state. Once device detects a short fault, it
latches the fault state in the DIAGn_SHORT fault register. The fault register value only recovers to normal when
LED fault disappears and the fault status is read back. Cycling Gx on and off does not clear the fault.
7.3.5 Thermal Shutdown
The TLC6C5816-Q1 device has an internal thermal sensor that monitors device temperature. Once the thermal
sensor detects device overtemperature, it disables all channel outputs and sets the TSD flag in the Fault
Readback register. The fault register value only recovers to normal when the overtemperature fault disappears
and the fault status is read back.
7.3.6 Command Error
The diagnostics configuration for DRAINn+1 and DIAGn cannot be set to open-drain output mode and diagnostics
mode at the same time. If the device detects both of the registers have been set high for any channel, the device
sets the CMD_ERR flag HIGH and pulls the open-drain error flag ERR pin low. Furthermore, the device ignores
the DIAGn setting and drives the channel in open-drain output mode. To reset the CMD_ERR flag, correct the
register configuration value and read out the fault register value.

ZHCSH63B –OCTOBER 2017–REVISED JANUARY 2020
7.3.7 Serial Communication Error
The device provides a cyclic redundancy check to verify register values in the shift registers. In readback mode,
the device provides 6 bits of the CRC remainder. The MCU can read back the CRC remainder and check if the
remainder is correct to determine whether the communication loop between MCU and device is good. Shift-
Register Communication-Fault Detection gives a detailed description of the CRC check.
7.3.8 Error Feedback
If any of the fault flags is high, ERR is pulled down. The MCU can detect the device fault by this pin, read out
fault flags, and take actions accordingly. The first RCK rising edge latches the fault registers into shift registers.
The status information shifts toward SER OUT at the falling edge of SRCK.
7.3.9 Interface
The TLC6C5816-Q1 device contains a 24-bit shift-register serial interface that feeds a 24-bit D-type storage
register. Data transfer through the shift and storage registers is on the rising edge of the shift register clock
(SRCK) and register latch signal (RCK), respectively. The storage register transfers data to the output buffer
when device enable (EN) is low and shift register clear (CLR) is high.
7.3.9.1 Register Write
The TLC6C5816-Q1 device has a 24-bit configuration register. Data transfers through the shift registers on the
rising edge of SRCK and latches into the storage registers on the rising edge of RCK. The first 8 data bits control
the diagnostics channel configuration, and the following 16 data bits control 16 open-drain outputs independently.

图 15. Register Write Timing Diagram
The DRAINn+1-DIAGn channel configuration is controlled by the DIAGn registers. These channels can be set to
either open-drain output or diagnostics input mode. The TLC6C5816-Q1 device does not allow the user to set
DRAINn+1 and DIAGn high at the same time, because the divider resistor for LED diagnostics can result in
leakage current on the LED, which lights up the LED. If the DIAGn and DRAINn registers are set to high at the
same time, the channel operates as an open-drain output instead of LED diagnostics, and a command error
latches in the fault registers, which can be read back by the register readback function as explained in Register
Read.
7.3.9.2 Register Read
The fault information loads to shift registers on the rising edge of RCK and can be read out on SER OUT. On the
rising edge of the RCK signal, the MSB data DIAG14_OPEN appears on the SER OUT pin. On each falling edge
of SRCK signal, there is 1 bit of data shifted out on the SER OUT pin. There is a total of 24 bits in the fault
information registers. Register Maps describes the details.

7.3.9.3 Shift-Register Communication-Fault Detection
The TLC6C5816-Q1 device provides a cyclic redundancy check to verify register values in the shift registers. In
readback mode, the TLC6C5816-Q1 device provides 6 bits of the CRC remainder. The MCU can read back the
CRC remainder and check if the remainder is correct. The CRC checksum provides a readback method to verify
shift register values without altering them.

图 17. CRC Check Block Diagram
The TLC6C5816-Q1 device also checks the configuration register for faulty commands.
The TLC6C5816-Q1 configuration register consists of 24 bits. To generate the CRC checksum, the device first
shifts left 6 bits and appends 0s, then bit-wise exclusive-ORs the 30 data bits with the polynomial to get the
checksum.
For example, if the configuration data is 0xD7i0F68 and the polynomial is 0x43 (7’b100i0011), the CRC
checksum is 0x19 (6’b01i1001).
The MCU can read back the CRC checksum and append it to the LSB of 24 bits, and then the 30 bits of data
becomes 0x35C3 DA19. Performing the bit-wise exclusive-OR operation with the polynomial should lead to a
residual of 0.

7.3.9.4 Clear Register
A logic low on CLR clears all registers in the device. TI suggests clearing the device registers during power up or
initialization.
7.3.9.5 Register Clock
RCK is the storage-register clock. Data in the storage register appears at the output whenever the output enable
(G1 and G2) input signals are low.

7.4 Device Functional Modes
7.4.1 Normal Operation
To make the device operate normally, usually use a 3.3-V or 5-V power supply to power VCC, connect the LED
supply voltage to a regulated voltage or directly to the car battery, and make sure the channel current does not
exceed 50 mA.
7.4.2 POR Reset
When VCC is lower than V(POR-falling), the device stops working and enters the power-off mode. When VCC is higher
than V(POR-rising), the device starts to work and sets all registers to their default values.
7.4.3 Standby Mode
When VCC is higher than V(POR-rising) and EN is high, the device enters the standby mode and sets all registers to
their default values. The power consumption is very low.

8 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLC6C5816-Q1 device usually is used to drive LED indicators in automotive cluster applications to convey
different kinds of information, such as airbag alert, engine fault, and so forth. Typically there are two types LED
indicators, general-purpose indicators and safety-related indicators. General indicators only require a simple
turnon and turnoff function. Safety-related indicators require not only LED on-off control, but also LED-open and -
short diagnostics. The TLC6C5816-Q1 device is very flexible, as it has 8 configurable LED diagnostics pins,
which can be configured as open-drain outputs or LED open- and short-diagnostics pins. By configuring
corresponding channels for the LED diagnostics function, the TLC6C5816-Q1 device can provide LED open and
short diagnostics to improve the system safety level. The following section describes a typical cluster application.
8.2 Typical Application
Following is a typical automotive cluster application which contains 24 LEDs. Two TLC6C5816-Q1 devices
connected in series drive the total of 24 LEDs. The first device drives 8 safety-critical LEDs which require LED
diagnostics, and the second device drives 16 general-purpose LEDs which only require simple on-and-off control.
An MCU, which controls the two devices through a serial interface and GPIOs, controls channel on-off, PWM
dimming, and LED diagnostics functions.

9 Power Supply Recommendations
The supply voltage range is from 3 V to 5.5 V for the TLC6C5816-Q1 device, which typically uses the same
supply voltage as the microcontroller, 3.3 V or 5 V. The LED supply voltage can be up to 40 V, so the LED
supply can use a car battery directly. Ensure the LED current is no greater than 50 mA during load dump
conditions. As the car battery varies a lot, to achieve stable LED brightness, a regulated voltage, for example
5 V, is preferred for the LED supply.

10 Layout
10.1 Layout Guidelines
To enhance the thermal performance, the TLC6C5816-Q1 device is designed with a thermal pad. TI
recommends to reserve enough copper area for a heat sink. To minimize the noise interference, it is
recommended to put the filter capacitor near the VCC pin. For a detailed layout example, see the following
example.
