Overview
The ST890CDR is a single-channel P-channel power switch manufactured by STMicroelectronics, designed for load switching applications. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum continuous output current of 1.2A. The device features a typical on-resistance of 75 milliohms and utilizes an 8-SOIC surface-mount package. Integrated protection mechanisms include adjustable current limiting and overtemperature shutdown. It functions with a non-inverting input interface and is rated for an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates adjustable current limiting and overtemperature fault protection for robust load management
- Features low on-resistance for efficient power delivery in compact surface-mount packages
- Supports high-side switching configuration with a simple non-inverting control interface
Applications
- Load switching in portable consumer electronics
- Power distribution in industrial control systems
- Peripheral power management in automotive infotainment units
Procurement Notes
Verify the specific suffix 'CDR' against official datasheets to confirm the tape-and-reel packaging quantity and RoHS compliance status. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference manufacturer documentation for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement specifications.
Selection Notes
Select the ST890CDR when a single-channel high-side switch with integrated thermal and current protection is required. It is suitable for applications needing low on-resistance and operation within standard 3.3V or 5V logic levels. Consider this component for space-constrained designs requiring surface-mount integration and reliable fault handling without external protection circuitry.
Part Context
The ST890CDR belongs to the ST890 family of power switches from STMicroelectronics. This series focuses on providing integrated protection features in small form factors. The CDR suffix typically denotes a specific reel packaging option within the broader ST890 product line, sharing core electrical specifications with other variants like the ST890BDR.
Replacement Considerations
The ST890CDR is documented as a parameter-equivalent replacement for the ST890BDR. Verify pin compatibility and electrical ratings before substitution.
