It features 8 open-drain DMOS transistor outputs rated at 40V and 50mA continuous sink current, with 200mA PWM peak capability. The device contains an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register with separate clocks (SRCK and RCK). The output enable (G) pin supports PWM dimming, while the CLR pin clears all registers simultaneously. Enhanced cascading via SER_OUT provides extra hold time for multi-device chains. Built-in thermal shutdown at 175\u00b0C and current derating with temperature protect the device. The slow output transition times (tr\/tf ~210ns\/128ns) significantly reduce EMI compared to standard logic outputs.","working_principle":"The TLC6C598 operates as a serial-to-parallel LED driver. Data is clocked into the 8-bit shift register on the rising edge of SRCK. After 8 bits are loaded, the RCK rising edge transfers the shift register data to the 8-bit storage register. When G is low (output enabled) and CLR is high, the storage register data drives the DMOS output transistors \u2014 a '1' turns the output ON (sinking current to GND through the LED), a '0' turns it OFF. The open-drain DMOS outputs can drive LEDs connected to a separate supply voltage up to 40V, independent of the 3-5.5V logic supply. PWM dimming is achieved by toggling the G pin at the desired duty cycle. For cascading multiple devices, SER_OUT provides the shift register output on the falling edge of SRCK, ensuring adequate hold time for the next device's SER_IN. The thermal shutdown disables all outputs when the junction temperature exceeds 175\u00b0C, and output current naturally decreases at higher temperatures for additional self-protection.","pin_description":"

      • Automotive Tell-Tale Indicators:<\/b> Drive 8 warning\/tell-tale LEDs (check engine, oil pressure, battery, etc.) in an instrument cluster. The MCU sends 8 bits of LED state via SPI-like serial interface (SER_IN, SRCK, RCK). The G pin controls PWM dimming for night-time brightness adjustment. The AEC-Q100 qualification ensures reliable operation in the automotive under-dash environment.<\/li>
      • 7-Segment Display Multiplexing:<\/b> Use two TLC6C598 devices cascaded \u2014 one for segment drives (a-g + DP) and one for digit enables. The 50mA per-channel current is sufficient for bright automotive displays. The slow output transitions reduce EMI that could interfere with sensitive RF receivers in the vehicle.<\/li>
      • Industrial PLC Status Panel:<\/b> Drive 8 status indicator LEDs on a PLC front panel. The 40V output rating allows driving 12V or 24V industrial LEDs directly. Cascading multiple TLC6C598 devices creates a 16-, 24-, or 32-LED indicator panel using only 3 MCU pins (SER_IN, SRCK, RCK) plus G for global enable.<\/li><\/ul>","alternative_models":"
