Overview
The OP526,005 is a high-side switch manufactured by WeEn Semiconductors. It integrates a single N-channel power MOSFET with diagnostic and protection features in a compact SOT363 surface-mount package. The device supports a supply voltage range of 4.5 V to 28 V, enabling operation in automotive and industrial environments. Key electrical characteristics include a maximum on-resistance of 1.7 ohms at 25°C and a continuous load current capability of 150 mA. The component includes built-in thermal shutdown and reverse polarity protection to ensure system reliability under fault conditions.
Feature Summary
- Integrated high-side switching with low on-state resistance for efficient power delivery
- Built-in thermal shutdown protection to prevent damage during overheating events
- Reverse polarity protection to safeguard the circuit against incorrect power connections
Applications
- Automotive lighting control modules
- Industrial relay driver circuits
- General-purpose load switching in embedded systems
Procurement Notes
Verify the specific ordering code suffix to confirm the tape and reel packaging quantity and variant details. Ensure the procurement channel provides traceability documentation consistent with automotive quality standards. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and updated electrical limits before finalizing purchase orders.
Selection Notes
Select this component when a single-channel high-side switch with integrated protection is required. Compare the 1.7-ohm on-resistance against load requirements to manage power dissipation. Consider the SOT363 package size constraints and thermal performance relative to ambient operating temperatures. Verify that the 28 V maximum supply voltage aligns with the system's nominal rail specifications.
Part Context
This part belongs to the WeEn Semiconductors high-side switch portfolio, designed for robust load management. It serves as a discrete alternative to complex driver ICs, offering simplified integration for single-load applications. The device complements other switches in the series by providing a balance of performance and protection in a minimal footprint suitable for space-constrained designs.
Replacement Considerations
Consult official substitution lists for equivalent high-side switches from WeEn or other manufacturers. Verify pin-to-pin compatibility and matching electrical parameters such as on-resistance and voltage ratings. Ensure replacement components meet the same automotive qualification standards if applicable.
