Overview
The STP08CL596MTR is an LED driver IC featuring a linear topology and shift register architecture. It provides eight output channels with a maximum current of 90mA per channel. The device operates within a supply voltage range of 3V to 3.6V and supports output voltages up to 16V. It functions at a frequency of 25MHz and includes internal switches. The component is housed in a 16-TSSOP package with a width of 4.40mm and is rated for an operating temperature range of -40°C to 125°C.
Feature Summary
- Integrates an 8-bit serial-in, parallel-out shift register feeding a D-type storage register for data handling.
- Provides regulated constant current sources to drive LEDs with adjustable intensity via external components.
- Supports high-speed clock frequencies to facilitate high-volume data transmission requirements.
Applications
- LED panel displays
- Low-voltage microcontroller interfacing
- High-density lighting systems
Procurement Notes
Verify the specific suffix 'MTR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Confirm that the part status is active or obsolete as required by the project lifecycle. Ensure the 16-TSSOP package dimensions align with the PCB footprint design constraints before finalizing procurement orders.
Selection Notes
Select this component when designing low-voltage LED systems requiring precise current regulation and serial data control. The 3.3V supply compatibility makes it suitable for modern microcontrollers. Consider the thermal performance of the TSSOP package if driving multiple channels simultaneously at higher currents within the specified limits.
Part Context
This part belongs to the STP08CL596 series from STMicroelectronics, designed specifically for LED display applications. It serves as a power shift register capable of sinking current to drive LED segments. The series is characterized by its ability to interface directly with low-voltage logic while providing robust output driving capabilities for display panels.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material.
FAQ
How is the LED brightness adjusted?
Brightness intensity can be adjusted from 0% to 100% via the Output Enable (OE) pin or through an external resistor setting the output current.
What is the maximum output voltage capability?
The device guarantees an output driving capability of up to 16V, allowing users to connect more LEDs in series.
