Overview
The PCA9959HNMP is a 24-bit constant current LED driver IC manufactured by NXP Semiconductors. It features a 10 MHz SPI interface and is housed in an HVQFN40 package. The device supports a supply voltage range of 2.7 V to 5.5 V, with an operating frequency of 20 MHz. It provides 24 output channels with a maximum output current of 63 mA per channel. The power dissipation capability is rated at 3.3 W. The component operates within a temperature range of -40°C to +85°C and includes low-level output currents of 3 mA.
Feature Summary
- Integrates 24 independent constant current output channels for precise LED control
- Supports high-speed serial communication via a 10 MHz SPI interface
- Incorporates boost and buck topology capabilities for flexible power management
Applications
- LED lighting driver systems
- General-purpose LED illumination control
- Electronic display backlighting modules
Procurement Notes
Verify the specific ordering suffix and packaging configuration against official NXP documentation before procurement. Confirm that the HVQFN40 package orientation and pinout match the target PCB layout requirements. Ensure that the 10 MHz SPI interface timing specifications are compatible with the host controller's clock capabilities to guarantee reliable data transmission during operation.
Selection Notes
Select this component when a high channel count with individual current control is required for LED arrays. The 10 MHz SPI interface allows for rapid updates compared to slower bus protocols. Consider the thermal performance given the 3.3 W power dissipation rating and the compact HVQFN40 footprint. Verify that the 2.7 V to 5.5 V input voltage range aligns with the system's power supply architecture.
Part Context
The PCA9959HNMP belongs to the PCA9959 series of LED drivers from NXP Semiconductors. This series is designed for applications requiring multiple individually addressable LED outputs. The device utilizes a standard HVQFN40 surface-mount package, facilitating integration into space-constrained electronic designs while providing robust electrical characteristics for consistent LED performance.
