When data is high, the DMOS transistor outputs have sink-current capability. The serial output (SER OUT) clocks out of the device on the falling edge of SRCK to provide additional hold time for cascaded applications. This provides improved performance for applications where clock signals may be skewed, devices are not located near one another, or the system must tolerate electromagnetic interference. The device contains a built-in thermal shutdown protection. Outputs are low-side, open-drain DMOS transistors with output ratings of 40 V and 50-mA continuous sink-current capabilities when VCC = 5 V. The current limit decreases as the junction temperature increases for additional device protection. The device also provides up to 2000 V of ESD protection when tested using the human-body model and 200 V when tested using the machine model. The TLC6C5912-Q1 characterization is for operation over the operating ambient temperature range of −40°C to 125°C. Device Information(1) 3 Description The TLC6C5912-Q1 is a monolithic, medium-voltage, low-current power 12-bit shift register designed for use in systems that require relatively moderate load power, such as LEDs. This device contains a 12-bit serial-in, parallel-out shift register that feeds a 12-bit D-type storage register. Data transfers through both the shift and storage registers on the rising edge of the shiftregister clock (SRCK) and the register clock (RCK), respectively. The storage register transfers data to the output buffer when shift register clear (CLR) is high. A low on CLR clears all registers in the device. Holding the output enable (G) high holds all data in the output buffers low, and all drain outputs are off. Holding G low makes data from the storage register transparent to the output buffers.

I/O DESCRIPTION Shift register clear, active-low: CLR is the signal used to clear all the registers. The storage register transfers data to the output buffer when shift register clear CLR is high. Driving CLR is low clears all the registers in the device.

Having G low enables all drain channels according to the output-latch register content. When high, all channels are off. GND 20 — Power ground: GND is the ground reference pin for the device. This pin must connect to the ground plane on the PCB. RCK 12 I Register clock: RCK is the storage register clock. The data in each shift register stage transfers to the storage register at the rising edge of RCK. Data in the storage register appears at the output whenever the output enable G̅ input signal is high. SER IN 2 I Serial-data input: SER IN is the serial data input. Data on SER IN loads into the internal register on each rising edge of SRCK. Open-drain output: DRAIN0 to DRAIN11 are the LED current-sink channels. These pins connect to the LED cathodes, and they can survive up to 40-V LED supply voltage. This is quite helpful during automotive load-dump conditions.

I/O DESCRIPTION SER OUT 11 O Serial-data output: SER OUT is the serial data output of the 12−bit serial shift register. The purpose of this pin is to cascade several devices on the serial bus. By connecting the SER OUT pin to the SER IN input of the next device on the serial bus to cascade, the data transfers to the next device on the falling edge of SRCK. This can improve the cascade application reliability, as it can avoid the issue that the second device receives SRCK and data input at the same rising edge of SRCK. SRCK 19 I Shift-register clock: SRCK is the serial clock input. On each rising SRCK edge, data transfers from SER IN to the internal serial shift registers. VCC 1 I Power supply: VCC is the power supply pin voltage for the device. TI recommends adding a 0.1 μF ceramic capacitor close to the pin. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN VCC Logic supply voltage VI Logic input-voltage –0.3 VDS Power DMOS drain-to-source voltage Continuous total dissipation Operating junction temperature Tstg Storage temperature (1) UNIT 8 V 8 V 42 V See Thermal Information Operating ambient temperature (Top) TJ MAX 125 °C –40 150 °C –55 165 °C Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.

The device contains a 12-bit serial-in, parallel-out shift register that feeds a 12-bit D-type storage register.

The thermal shutdown forces the device to have an open state when the junction temperature exceeds the thermal trip threshold. Once the junction temperature decreases to less than 160°C (typical), the device begins to operate again. 10 Submit Documentation Feedback Copyright © 2012–2016, Texas Instruments Incorporated Product Folder Links: TLC6C5912-Q1 TLC6C5912-Q1 www.ti.com SLIS141C – DECEMBER 2012 – REVISED JULY 2016 Feature Description (continued) 8.3.2 Serial-In Interface The TLC6C598 device contains an 8-bit serial-in, parallel out shift register that feeds an 8-bit D-type storage register. Data transfer through both the shift and storage registers on the rising edge of the shift register clock (SRCK) and the register clock (RCK), respectively. The storage transfers data to the output buffer when shift register clear (CLR) is high. 8.3.3 Clear Register A logic low on CLR clears all registers in the device. TI suggests clearing the device during power up or initialization. 8.3.4 Cascade Through SER OUT By connecting the SER OUT pin to the SER IN input of the next device on the serial bus to cascade, the data transfers to the next device on the falling edge of SRCK. This can improve the cascade application reliability, as it can avoid that the second device receives SRCK and data input at the same rising edge of SRCK. 8.3.5 Output Control Holding the output enable (G) high holds all data in the output buffers low, and all drain outputs are off. Holding G low makes data from the storage register transparent to the output buffers. When data in the output buffers is low, the DMOS transistor outputs are off. When data is high, the DMOS transistor outputs are capable of sinkcurrent. This pin also be used for global PWM dimming. 8.4 Device Functional Modes 8.4.1 Operation With VCC < 3 V This device works normally during 3 V ≤ VCC ≤ 5.5 V, when operation voltage is lower than 3 V. The behavior of device cannot be ensured, including communication interface and current capability. 8.4.2 Operation With 5.5 V ≤ VCC ≤ 8 V The device works normally during this voltage range, but reliability issues may occurs while the device works for a long time in this voltage range.

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. 9.1 Application Information The TLC6C5912-Q1 device is a serial-in, parallel-out, power logic 8-bit shift register with low-side open-drain DMOS output rating of 40 V and 50-mA continuous sink-current capabilities when VCC= 5 V. The device is designed to drive resistive loads and is particularly well-suited as an interface between a microcontroller and LEDs or lamps. The device also provides up to 2000 V of ESD protection when tested using the human body model and 200 V when using the machine model. 9.2 Typical Application Figure 13 shows a typical cascade application circuit with two TLC6C5912-Q1 chips configured to cascade topology.

This input supply should be well regulated. TI recommends placing the ceramic bypass capacitors near the VCC pin. 11 Layout 11.1 Layout Guidelines There are no special layout requirement for the digital signal pins. The only requirement is placing the ceramic bypass capacitors near the corresponding pin. Maximize the copper coverage on the PCB to increase the thermal conductivity of the board. The major heat-flow path from the package to the ambient is through the cooper on the PCB. Maximizing the copper coverage is extremely important when the design does not include heat sinks attached to the PCB on the other side of the package. • Add as many thermal vias as possible directly under the package ground pad to optimize the thermal conductivity of the board. • All thermal vias should be either plated shut or plugged and capped on both sides of the board to prevent solder voids. To ensure reliability and performance, the solder coverage should be at least 85%. 11.2 Layout Example Vcc 1 20 GND SER IN 2 19 SRCK DRAIN0 3 18 DRAIN11 DRAIN1 4 17 DRAIN10 DRAIN2 5 16 DRAIN9 DRAIN3 6 15 DRAIN8 DRAIN4 7 14 DRAIN7 DRAIN5 8 13 DRAIN6 CLR 9 12 RCK G 10 11 SER OUT Figure 15.
