PCA9530DP,118

Overview

The PCA9530DP,118 is an NXP Semiconductors LED driver IC featuring two linear outputs with a maximum current of 25 mA per channel. It operates on a 2.3 V to 5.5 V supply voltage and supports I²C/SMBus communication at frequencies up to 400 kHz. The device is housed in an 8-TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports I²C and SMBus interfaces for digital control
• Provides linear dimming capability for LED brightness adjustment
• Features internal power-on reset for reliable initialization

Applications

• LED backlighting systems
• General LED illumination control
• Embedded display lighting applications

Procurement Notes

Verify the specific suffix DP against official NXP documentation to confirm the TSSOP-8 package variant. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Cross-reference the manufacturer part number with authorized distributor databases to ensure authenticity and traceability before procurement.

Selection Notes

Select this component when precise linear dimming control is required for low-current LEDs via I²C. Ensure the system voltage aligns with the 2.3 V to 5.5 V operating range. Consider the 8-TSSOP footprint constraints and thermal requirements for the target application environment.

Part Context

This part belongs to the PCA9530 series of LED controllers designed for simple I²C-based lighting management. It serves as a compact solution for managing small arrays of LEDs where microcontroller GPIO pins are limited, offering dedicated drive capability without complex external circuitry.

Replacement Considerations

Consult NXP official substitution lists for direct replacements. Verify pin compatibility and electrical specifications if considering alternative manufacturers.
