Description and Introduction

18 V tolerant SPI 16-bit/8-bit GPI with INT The **PCA9702PW** from NXP Semiconductors is a versatile LED driver designed for applications requiring efficient and reliable control of multiple LEDs. This 16-bit constant-current sink driver features an I²C-bus interface, enabling seamless integration with microcontrollers and digital systems for precise LED brightness adjustment.  

With a wide operating voltage range of 2.3V to 5.5V, the PCA9702PW is suitable for both low-power and standard-voltage applications. Each output channel provides a constant current, ensuring uniform brightness across LEDs while minimizing power dissipation. The device supports programmable current levels, allowing fine-tuning for different LED types and applications.  

Key features include thermal shutdown protection, open-load detection, and error flag reporting, enhancing system reliability. The PCA9702PW is ideal for automotive lighting, industrial displays, and consumer electronics where consistent LED performance is critical.  

Housed in a TSSOP24 package, the component offers a compact footprint for space-constrained designs. Its robust performance and flexible configuration make it a practical choice for engineers seeking a high-performance LED driver solution.  

By combining efficiency, protection features, and ease of control, the PCA9702PW delivers a dependable solution for modern LED driving requirements.

Application Scenarios & Design Considerations

Alternative Part Number

  • TCA9535PW --: 16-bit I2C/SMBus I/O expander in TSSOP package, functionally similar GPIO expansion role with interrupt output and wide supply range.
  • PCF8575CPW --: 16-bit I2C I/O expander in TSSOP, same vendor family concept but different series naming, suitable for GPIO expansion applications.
  • MAX7325AUP+ --: I2C port expander with 16 I/O and interrupt, alternative architecture for keypad/GPIO expansion in compact packages.
