Product details
Overview
TLC59116FIRHBR from Texas Instruments is a 16-channel I²C-bus LED driver optimized for RGBA color mixing, featuring individual 256-step (8-bit) PWM at 97 kHz per channel, group dimming/blink control at 190 Hz or 24 Hz–10.73 s, and 120 mA per output with 17 V tolerance - used in gaming UIs, industrial status indicators, and small signage backlighting.
For engineers reviewing the TLC59116FIRHBR datasheet, TLC59116FIRHBR pinout, TLC59116FIRHBR application, or TLC59116FIRHBR equivalent, key selection considerations include its Fast-Mode Plus (1 MHz) I²C interface with 30 mA SDA drive, hardware address pins (A0–A3) enabling up to 14 devices on one bus, active-low RESET, and support for both 3.3 V and 5 V supply operation.
Technical Context
The TLC59116FIRHBR integrates two independent PWM engines: a per-channel 97 kHz fixed-frequency controller (256-step duty cycle, 0%–99.6%) and a group-level controller offering either 190 Hz fixed-frequency dimming or programmable blink frequency (24 Hz to 10.73 s). Its I²C interface complies with Fast-Mode Plus (1 MHz), includes noise filtering on SCL/SDA, and supports hot insertion.
Each of the 16 open-drain outputs operates with ≤450 mV low-level voltage at 120 mA (VCC = 3 V), features 17 V output voltage tolerance, and uses an internal 25 MHz oscillator - eliminating external timing components. The device implements software reset (SWRST call at address D6h), power-on reset, and external active-low RESET with pullup requirement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCA9685PW | 16-channel, 200 Hz–1.6 kHz programmable PWM; no group blink mode; 25 mA per channel; 5.5 V max output. | Limited to lower-current LEDs; lacks 24 Hz–10.73 s blink range and 17 V tolerance - unsuitable for high-Vf LED strings. | Choose PCA9685PW only for low-power, low-Vf indicator LEDs where extended blink timing and high output voltage are unnecessary. |
| IS31FL3731-QFLS4-TR | 18-channel, 256-step PWM at 1.2 kHz; integrated auto-breathing; 40 mA per channel; no hardware address pins. | Higher PWM frequency reduces audible noise but limits peak current; no A0–A3 addressing - requires I²C multiplexer for >1 device. | Select IS31FL3731-QFLS4-TR for noise-sensitive consumer audio devices; avoid when driving high-current LEDs or requiring multi-drop I²C topology. |
Compared with PCA9685PW and IS31FL3731-QFLS4-TR, the TLC59116FIRHBR uniquely combines 120 mA per channel, 17 V output tolerance, hardware-addressable multi-drop capability, and programmable blink timing down to 24 Hz - making it the only option among the three suitable for industrial signage and high-Vf RGB LED arrays.

FAQ
What is the maximum output current per channel for the TLC59116FIRHBR?
The TLC59116FIRHBR supports up to 120 mA per output channel (OUT0–OUT15) under recommended operating conditions. This rating applies at VCC = 3 V to 5.5 V and TA = –40°C to +85°C, with VOL ≤ 450 mV at 120 mA. Exceeding this current risks thermal shutdown or long-term reliability degradation.
Does the TLC59116FIRHBR require an external oscillator or crystal?
No, the TLC59116FIRHBR integrates a 25 MHz internal oscillator that requires no external components. This eliminates the need for crystals, capacitors, or timing resistors - simplifying PCB layout, reducing BOM cost, and improving startup reliability across temperature and voltage variations.
Can the TLC59116FIRHBR drive LEDs with forward voltages above 5 V?
Yes, the TLC59116FIRHBR outputs are rated for up to 17 V, allowing direct connection to LED strings with combined forward voltages up to 17 V (e.g., 5× white LEDs at 3.4 V each). The device operates as a constant-current sink, so external current-setting resistors are not required.
How many TLC59116FIRHBR devices can share the same I²C bus?
Up to 14 TLC59116FIRHBR devices can coexist on a single I²C bus using the A0–A3 hardware address pins. Each device responds to a unique 4-bit address (14 valid combinations), and additional grouping is supported via software-configurable All-Call (D0h) and Sub-Call (D2h/D4h/D8h) addresses.
What is the function of the RESET pin on the TLC59116FIRHBR?
The RESET pin on the TLC59116FIRHBR is an active-low asynchronous input that forces all internal registers to their power-on-reset (POR) default state, setting all outputs high (LEDs OFF). It requires an external pullup resistor if left unconnected and must be held low for ≥10 ns to trigger reset.
