Product details
Overview
PCA9622DR,118 from NXP Semiconductors is a 16-channel I²C-bus LED driver IC with open-drain 100 mA outputs rated to 40 V, supporting individual 97 kHz PWM brightness control (256 steps) and group-level dimming/blinking (190 Hz fixed or 24 Hz–10.73 s programmable). It operates from 2.3 V to 5.5 V and targets RGB/RGBA LED arrays in status indicators and keypad backlights.
For engineers reviewing the PCA9622DR,118 datasheet, PCA9622DR,118 pinout, PCA9622DR,118 application, or PCA9622DR,118 equivalent, key selection criteria include its Fast-mode Plus (1 MHz) I²C interface, hardware addressability for up to 126 devices, active-low OE pin for synchronized hardware blinking, and dual-layer PWM architecture enabling per-LED + global intensity control without MCU overhead.
Technical Context
The PCA9622DR,118 integrates a 25 MHz internal oscillator (no external components required), noise-filtered SDA/SCL inputs, and power-on reset logic. Its register map includes 16 individual PWM registers (02h–11h), GRPPWM (12h) and GRPFREQ (13h) for group control, and LEDOUT0–LEDOUT3 (14h–17h) defining output state mode (off/on/individual/group).
It supports four software-configurable I²C addresses: one LED All Call (E0h default), three Sub Call addresses (E2h/E4h/E8h), plus dedicated Software Reset (06h). Output state update can be configured to occur on STOP (default) or ACK command, enabling synchronized multi-device updates across large LED arrays.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCA9635PW,118 | Same register map and software compatibility; higher-voltage (50 V) open-drain outputs; no integrated 100 mA FETs - requires external drivers | Better suited for driving high-Vf LED strings (e.g., >3.5 V per LED) or higher-current configurations beyond 100 mA/channel | Select PCA9635PW,118 when output voltage headroom >40 V or external driver flexibility is required; retains identical firmware and bus protocol. |
| TLC5940QPWPRQ1 | 16-channel, 12-bit PWM (4096 steps); 125 mA constant-current sink; no group PWM; uses dot-correction and grayscale registers instead of simple duty-cycle values | Targeted at high-precision LED signage and automotive interior lighting where grayscale fidelity and current matching outweigh simplicity | Choose TLC5940QPWPRQ1 for applications demanding <1% current matching or >10-bit brightness resolution; note incompatible register structure and no built-in group control. |
Compared with PCA9622DR,118, the PCA9635PW,118 offers extended voltage capability but requires external drivers, while the TLC5940QPWPRQ1 delivers finer grayscale control at the cost of increased register complexity and no native group dimming - making PCA9622DR,118 optimal for cost-sensitive, software-simple RGB status and backlight systems.

FAQ
What is the maximum number of PCA9622DR,118 devices supported on a single I²C bus?
The PCA9622DR,118 supports up to 126 devices on one I²C bus using its 7 hardware address pins (A0–A6). Two addresses (Software Reset and LED All Call) are reserved at power-up, leaving 126 usable slave addresses. This enables large-scale LED arrays without bus segmentation or repeaters.
Does PCA9622DR,118 require an external crystal or RC network for timing?
No, the PCA9622DR,118 contains a fully integrated 25 MHz oscillator requiring no external components. This eliminates timing component costs and layout sensitivity while ensuring stable 97 kHz individual PWM and 190 Hz group PWM frequencies across voltage and temperature.
Can PCA9622DR,118 drive LEDs with forward voltages above 5.5 V?
Yes - the PCA9622DR,118 features 40 V-tolerant open-drain outputs. When used with an external current-limiting resistor or series string, it can drive LEDs or LED strings with total forward voltage up to 40 V, independent of its 2.3–5.5 V VDD supply.
How does the OE pin interact with internal group blinking (DMBLNK = 1)?
Using the OE pin for external blinking while DMBLNK = 1 in MODE2 register results in undefined behavior per the datasheet. The OE pin must be held HIGH (disabled) during internal group blinking to ensure predictable timing and avoid signal contention between hardware and register-controlled modulation.
Is PCA9622DR,118 pin-compatible with PCA9625 or PCA9635?
No - while PCA9622DR,118 shares identical software register mapping and I²C protocol with PCA9625 and PCA9635, its TSSOP32 pinout differs. PCA9625 uses HVQFN24 and PCA9635 uses TSSOP24 packages; none are pin-to-pin compatible. PCB layout must be redesigned for each variant.
