Overview
The MC20XS4200FK is a dual high-side power switch manufactured by NXP Semiconductors. It integrates two independent channels with a maximum on-resistance of 10 mOhm per channel. The device operates within an input voltage range of 6 V to 58 V and supports an operating supply voltage of 3 V to 5.5 V. It utilizes a serial interface for control and is housed in a 23-pin PQFN package. The component is rated for automotive applications, functioning reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Dual-channel high-side switching architecture
- Automotive-grade reliability and robustness
- Integrated thermal protection mechanisms
Applications
- Automotive body and vehicle control systems
- Powertrain management modules
- Industrial motor control interfaces
Procurement Notes
Verify the specific suffix and marking configuration against the official datasheet to ensure compatibility with existing board layouts. Confirm current lifecycle status as distribution availability may be limited due to end-of-life planning. Validate that the selected packaging format meets assembly requirements before finalizing orders.
Selection Notes
Select this component when designing circuits requiring dual high-side loads with low on-resistance characteristics. Ensure the system input voltage does not exceed the 58 V absolute maximum rating. Verify that the serial communication protocol aligns with the host controller's capabilities and that the thermal dissipation design accommodates the PQFN package constraints.
Part Context
This part belongs to NXP's MC20XS series of high-side switches designed for demanding automotive environments. The series provides scalable solutions for managing multiple power outputs with integrated diagnostics. It complements other NXP power management and microcontroller families used in vehicle electrification and control architectures.
Replacement Considerations
Check for form-fit-function compatible alternatives from the same product family if supply is constrained. Verify that any substitute maintains the 10 mOhm resistance specification and 23-pin PQFN footprint.
