Product details
Overview
PCA9632DP1,118 from NXP Semiconductors is a 4-bit Fast-mode Plus (Fm+) I²C-bus LED driver optimized for RGBA color mixing, featuring 4 open-drain/totem-pole LED outputs with 25 mA sink capability at 5 V, 1.5625 kHz individual PWM (256-step), and 190 Hz group PWM (16-step), deployed in status indicators and keypad backlights.
For engineers reviewing the PCA9632DP1,118 datasheet, PCA9632DP1,118 pinout, PCA9632DP1,118 application, or PCA9632DP1,118 equivalent, key selection considerations include I²C address configuration (fixed 8-pin address), TSSOP8 package constraints, low-power operation (<1 μA standby), 2.3–5.5 V supply range, and software reset via SWRST call (0x06).
Technical Context
The PCA9632DP1,118 implements dual PWM control: an 8-bit individual controller per LED (1.5625 kHz, 0–99.6% duty) and a 4-bit group controller (190 Hz, 0–93.75% duty) for synchronized dimming. It uses a 400 kHz internal oscillator with no external components required.
I²C interface operates up to 1 MHz (Fm+), supports 30 mA SDA drive strength, noise filtering on SCL/SDA, edge rate control, and hot insertion. The device features volatile register mapping (MODE1/MODE2, PWM0–PWM3, GRPPWM, GRPFREQ, LEDOUT) with Auto-Increment options for sequential writes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC59116IPWPR | 16-channel, 12-bit PWM, 1 MHz I²C, but no group blinking mode or GRPFREQ register | Higher channel count suits larger displays; lacks built-in blink period programming | Select when scalability beyond 4 LEDs is required and blink control is handled externally |
| IS31FL3728-QFLS4-TR | 8-bit PWM, 28-channel, integrated current regulation, but requires external clock and has no SWRST call | Superior current matching for uniform LED arrays; no software reset via I²C | Prefer for high-channel-count lighting where precision current sourcing outweighs reset convenience |
Compared with TLC59116IPWPR and IS31FL3728-QFLS4-TR, the PCA9632DP1,118 offers unique group blink period programming (GRPFREQ), ultra-low standby current (<1 μA), and hardware-compatible TSSOP8 footprint-making it optimal for space-constrained, battery-sensitive RGBA UIs.

FAQ
What is the I²C target address of the PCA9632DP1,118?
The PCA9632DP1,118 uses a fixed 7-bit I²C target address of 0xC0 (1100000b) with R/W bit appended. Unlike the 10-pin PCA9632DP2 variant, the TSSOP8 PCA9632DP1,118 does not support hardware address pins (A0/A1), so only one device can occupy this address on a given bus unless using LED All Call (E0h) or Sub Call addresses.
Can the PCA9632DP1,118 drive LEDs directly without external components?
Yes - the PCA9632DP1,118 can directly drive standard LEDs with up to 25 mA per channel at 5 V supply. Its outputs are 5.5 V tolerant, and the internal 400 kHz oscillator eliminates need for external timing components. Open-drain mode is recommended for LEDs with integrated Zener protection; totem-pole mode improves efficiency for standard LEDs.
How does the PCA9632DP1,118 achieve synchronized LED updates across multiple devices?
The PCA9632DP1,118 supports "Change on STOP" output update mode (OCH bit = 0 in MODE2). When enabled, all LED states (brightness, on/off, blink) are latched simultaneously upon I²C STOP condition - ensuring pixel-perfect synchronization across multiple PCA9632DP1,118 units sharing the same bus.
What is the minimum pulse width supported for blink functionality in the PCA9632DP1,118?
The shortest blink period supported by the PCA9632DP1,118 is 41 ms (24 Hz), achieved when GRPFREQ register is set to 0x00. This corresponds to the highest group blink frequency; longer periods extend to 10.73 seconds (0x00 → 0xFF linear scale), enabling both rapid alerts and slow status indicators.
Does the PCA9632DP1,118 support hot insertion?
Yes - the PCA9632DP1,118 explicitly supports hot insertion per its datasheet. Input pins (SCL, SDA, VDD, VSS) include ESD protection (>5000 V HBM), noise filters, and edge rate control, allowing safe connection/disconnection while the I²C bus remains active - critical for field-serviceable LED modules.
