PCA9622BS,118

Overview

The PCA9622BS,118 is an NXP LED driver IC featuring 16 outputs with linear PWM dimming and a 100 mA sink current capability. It operates on a 2.3 V to 5.5 V supply within a -40°C to +85°C range. The device utilizes a 1 MHz I²C interface for control and is housed in an HVQFN28 package.

Feature Summary

• Supports 16-channel linear PWM dimming for precise brightness control
• Integrates a high-speed 1 MHz I²C bus interface for communication
• Provides individual output control with programmable frequency and duty cycle

Applications

• LED backlighting systems
• General LED illumination
• Display panel driving

Procurement Notes

Verify the specific suffix 'BS' corresponds to the HVQFN28 package variant when sourcing. Confirm RoHS compliance status through official documentation. Ensure the component matches the active status indicated by the manufacturer before finalizing procurement plans.

Selection Notes

Select this component for designs requiring 16 individually controllable channels with moderate sink current. The HVQFN28 package suits compact surface-mount layouts. Verify that the 1 MHz I²C speed aligns with system timing requirements and that the linear PWM architecture fits the application's dimming needs.

Part Context

This part belongs to the PCA9622 family of LED controllers from NXP. It shares core functionality with variants like the PCA9622DR but differs in packaging. The BS suffix specifically denotes the HVQFN28 form factor, distinguishing it from TSSOP options within the same product line.

Replacement Considerations

The PCA9622DR,118 serves as a direct functional substitute using a 32-TSSOP package. Designers must account for pinout compatibility and thermal dissipation differences between the HVQFN28 and TSSOP-32 footprints during replacement.
