STP16CPS05MTR

Overview

The STP16CPS05MTR is a monolithic, low-voltage LED display driver featuring sixteen constant current sink channels. It integrates a 16-bit serial-in parallel-out shift register and a D-type storage register. The device operates on a supply voltage ranging from 3V to 5.5V and supports a maximum clock frequency of 30MHz for high-speed data transmission. Output currents are adjustable between 5mA and 100mA via an external resistor, with a guaranteed output driving capability of 20V. It includes auto power-saving features and ESD protection rated at 2kV HBM.

Feature Summary

• Integrates sixteen regulated constant current sources for direct LED driving
• Features auto power-shutdown and auto power-on capabilities to minimize quiescent current
• Supports high-speed serial data transmission with a maximum clock frequency of 30MHz
• Includes built-in ESD protection against electrostatic discharge events

Applications

• LED panel displays requiring low voltage operation
• Systems interfacing directly with 3.3V microcontrollers
• High data rate transmission applications
• Battery-powered devices utilizing auto power-saving modes

Procurement Notes

Verify the specific package variant, as the base part number may correspond to different packaging options such as TSSOP or SOIC. Confirm RoHS compliance status and ensure the ordering suffix matches the required reel quantity. Check for obsolescence notices, as earlier versions like the non-MTR variant may be discontinued. Validate that the 24-pin package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when designing LED matrices that require precise current regulation without external transistors. It is suitable for applications needing brightness control through external resistors rather than PWM. Consider the thermal performance of the 24-SOP package for high-density layouts. Ensure the system voltage remains within the 3V to 5.5V range to maintain proper logic levels and output drive capability.

Part Context

This device belongs to the STP16CP05 series of low-voltage LED drivers. It shares functional similarities with other members like the STP16CPPS05 but differs in package type and specific current ranges. The series is designed for cost-effective LED panel solutions, offering integrated shift registers and latches to simplify interface circuitry compared to discrete driver implementations.

Replacement Considerations

STP16CP05MTR is listed as a parameter-equivalent replacement. Verify pin compatibility and current specifications before substitution.
