Overview
The MC08XS6421DEKR2 is a high-side power switch IC from NXP Semiconductors, designed for power distribution applications. It features a dual-channel configuration with distinct on-resistance values of 8 mOhms and 21 mOhms per channel. The device operates within a load voltage range of 7 V to 18 V and requires a supply voltage between 4.5 V and 5.5 V. It utilizes an SPI interface for control and diagnostics. The component is housed in a 32-SOIC EP package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel high-side switching capability with differentiated low on-resistance paths
- Integrated fault protection including fixed current limiting, open-load detection, and over-temperature shutdown
- Digital control via Serial Peripheral Interface (SPI) for precise monitoring and management
Applications
- Automotive power distribution units
- Industrial motor control systems
- High-side load switching in embedded controllers
Procurement Notes
Verify the specific suffix 'DEKR2' against official NXP documentation to confirm reel packaging and tape specifications. Confirm end-of-life status as related variants show discontinuation. Ensure moisture sensitivity level handling procedures are followed during assembly. Cross-reference pinout compatibility if replacing existing designs.
Selection Notes
Select this component when dual independent high-side switches with asymmetric resistance requirements are needed. The SPI interface allows for detailed diagnostic feedback compared to basic logic-controlled switches. Consider the 32-pin SOIC EP package for thermal dissipation needs in compact layouts. Validate that the 18V maximum load voltage aligns with system bus requirements.
Part Context
This part belongs to the MC08XS6421 series of multi-channel PMICs from NXP. These devices integrate power switches with advanced diagnostic features for safety-critical applications. The series supports ASIL B/D functional safety requirements, making it suitable for automotive and industrial environments where reliability and fault detection are paramount.
Replacement Considerations
Check for MC08XS6421BEK or MC08XS6421BEKR2 as potential pin-compatible alternatives within the same family, though electrical parameters may vary slightly.
