Overview
The STP16CP596M is a low-voltage, 16-bit constant current LED sink driver manufactured by STMicroelectronics. It operates within an input voltage range of 3V to 3.6V and supports output voltages up to 20V. The device features a maximum power supply current of 14.1 mA and provides high-level and low-level output currents of 1 mA each. It utilizes serial and parallel interface types for data transmission. The component is housed in a 24-SOIC package with a width of 7.50 mm and functions as a linear LED display driver.
Feature Summary
- Provides constant current sinking capability for driving light-emitting diodes
- Integrates 16-bit shift register functionality for sequential data handling
- Supports both serial and parallel communication interfaces for flexible system integration
Applications
- LED display systems requiring constant current sink drivers
- Low-voltage lighting control circuits
- Digital signage modules utilizing serial or parallel data inputs
Procurement Notes
Verify the specific suffix and package variant against the original design requirements, as the STP16CP596M may be discontinued or superseded by newer revisions such as the STP16CP05 series. Confirm RoHS compliance status and check for parameter-equivalent substitutes if availability is limited. Ensure the selected replacement maintains identical pinout and electrical characteristics to avoid redesign efforts.
Selection Notes
Select this component when a 16-channel constant current sink driver is required for low-voltage LED applications. The 3V to 3.6V operating range suits battery-powered or logic-compatible systems. Consider the 24-SOIC package for surface-mount assembly constraints. Verify that the 1 mA output current meets the specific LED brightness requirements, as higher current options exist in other product families.
Part Context
This part belongs to the STP16CL596 family of LED display drivers from STMicroelectronics. It shares functional similarities with the STP16CPS05M but differs in specific electrical parameters and interface configurations. The device is designed for applications requiring reliable LED regulation with minimal external components, fitting into the broader category of linear LED driver ICs.
Replacement Considerations
The STP16CP596M is listed as obsolete. Parameter-equivalent alternatives include STP16CP05MTR, STP16CPC05MTR, and STP16CPS05MTR. These substitutes offer similar 16-bit constant current sinking capabilities but may have updated packaging or minor electrical differences requiring verification.
