BU16501KS2-E2

Overview

The BU16501KS2-E2 is an LED lighting driver IC manufactured by ROHM Semiconductor, designed for matrix drive applications. It features a 3-wire serial interface and supports PWM topology with I2C/SPI dimming capabilities. The device provides 16 outputs within a 24-channel configuration, housed in a 52-SQFP-T(10x10) package. It operates on a supply voltage range of 2.7 V to 5.5 V, with a maximum power dissipation of 1.3 W. The unit functions at a working frequency of 1.2 MHz and supports output currents of up to 680 mA per channel. It is rated for temperatures between -40°C and +85°C.

Feature Summary

• Supports LED matrix driving with linear I2C and SPI dimming control interfaces.
• Integrates internal switches for direct LED load management without external components.
• Provides high-level output current capability for efficient signal transmission.

Applications

• LED backlighting systems
• Digital signage displays

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with current environmental standards and pinout configurations. Ensure the ordering part number matches the exact package variant required for the PCB layout. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when designing LED matrix drivers requiring integrated switching and serial control. The 52-pin SQFP package suits space-constrained surface-mount designs. Verify that the system power supply remains within the 2.7 V to 5.5 V range and that the thermal design accommodates the specified power dissipation limits under maximum load conditions.

Part Context

This IC belongs to the BU16501 series of LED lighting drivers from ROHM Semiconductor. It is categorized under PMIC LED drivers and is distinct from audio codecs or battery management units found in other product lines. The device is specifically engineered for display illumination rather than general-purpose power regulation or data communication.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult the manufacturer directly for end-of-life notifications or recommended alternative components if discontinuation occurs.
