STP16CPC26XTR

Overview

The STP16CPC26XTR is a monolithic, low voltage, 16-bit constant current LED sink driver manufactured by STMicroelectronics. It integrates a 16-bit shift register and data latches to convert serial input into parallel output format. The device features sixteen regulated current generators providing an adjustable output current range of 5 mA to 90 mA per channel, externally set via a resistor. It supports a maximum clock frequency of 30 MHz for high-speed data transmission and guarantees a 20 V driving capability. The component operates within a supply voltage range of 3 V to 5.5 V and includes thermal shutdown protection at 170 °C.

Feature Summary

• Integrates a 16-bit shift register and data latches for serial-to-parallel data conversion
• Provides sixteen individually regulated constant current channels with adjustable output levels
• Supports high-speed data transmission through a 30 MHz clock frequency interface
• Includes thermal shutdown protection to prevent damage from overtemperature events

Applications

• LED matrix displays requiring individual pixel control
• High brightness LED array drivers
• Cost-effective lighting systems with row-wise scanning
• Digital signage banners with scrolling effects

Procurement Notes

Verify the package type matches the design requirements, as the STP16CPC26 family is available in multiple packages including TSSOP-24 with exposed pad, QSOP-24, SO-24, and HTSSOP-24. Ensure the specific suffix corresponds to the desired packaging configuration. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Cross-reference the ordering part number with official distributor catalogs to ensure correct variant selection.

Selection Notes

Select this component when a low-voltage, 16-channel constant current sink driver is required for LED applications. It is suitable for designs needing adjustable current up to 90 mA and high-speed serial interfacing. Consider the operating temperature range and thermal management needs due to the internal power dissipation. Verify that the system voltage falls within the 3 V to 5.5 V supply range and that the load does not exceed the 20 V rating per channel.

Part Context

The STP16CPC26XTR belongs to the STP16CPC26 family of LED drivers from STMicroelectronics. This family is designed for low-voltage applications and offers high accuracy in current regulation. The XTR suffix typically denotes a tape and reel packaging option, distinguishing it from cut tape or tube variants. The device is widely used in consumer electronics and industrial lighting where compact size and efficient drive capabilities are essential.

Replacement Considerations

Direct replacements must match the 16-bit constant current sink architecture and similar electrical specifications. Check for equivalent packages such as TSSOP-24 or compatible pin-outs if form factor constraints exist. Verify that alternative devices support the same 30 MHz clock speed and 20 V output voltage rating to ensure functional compatibility in existing designs.
