PCA9632DP2,118

Overview

The PCA9632DP2,118 is a 4-bit FM+ I²C-bus low-power LED driver manufactured by NXP Semiconductors. It features four open-drain outputs capable of sinking 25 mA each at 5 V, with a total package current limit of 100 mA. The device operates within a supply voltage range of 2.3 V to 5.5 V and supports I²C clock frequencies from 100 kHz to 1 MHz. It utilizes a 10-TSSOP surface-mount package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Four independent LED outputs with software-programmable open-drain configuration for flexible drive modes
• FM+ I²C interface supporting high-speed operation up to 1 MHz and dense bus loading capabilities
• Integrated internal oscillator enabling precise PWM dimming without external timing components
• Software reset functionality allowing immediate register reconfiguration via the I²C bus

Applications

• RGB/RGBA color mixing and palette applications
• Backlight control for displays and panels
• Programmable logic controller (PLC) indicator management
• Remote I/O panel-mounted controller systems

Procurement Notes

Verify component authenticity through authorized NXP channels or certified distributors. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Note that this specific part number may be subject to discontinuation; validate current manufacturing status and availability windows before finalizing design-in decisions.

Selection Notes

Select this component for designs requiring precise multi-channel LED intensity control via a standard serial interface. It serves as a direct hardware replacement for the PCA9633, offering reduced power consumption while maintaining compatible register structures. Ideal for space-constrained PCB layouts where TSSOP10 packaging and low standby current are critical requirements.

Part Context

This device belongs to the PCA9632 family of LED controllers designed for efficient light management. It replaces older generations like the PCA9633 with improved power efficiency. The chip integrates dedicated PWM generators for independent channel control and a group controller for synchronized operations, facilitating complex lighting effects in embedded systems.

Replacement Considerations

PCA9632DP2Z is confirmed as a direct substitute part number.
