BU29503KVT-E2

Overview

The BU29503KVT-E2 is a high-side switch manufactured by ROHM Semiconductor. It operates within an input voltage range of 4.5V to 36V and supports a maximum load current of 1.5A. This component is designed for efficient power switching applications requiring robust protection features.

Feature Summary

• Integrated high-side switching capability
• Wide operating voltage range up to 36V
• Supports continuous load currents up to 1.5A

Applications

• Automotive lighting control systems
• Industrial load switching
• General-purpose high-side power management

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to ensure compliance with current environmental standards and pinout configurations. Confirm that the 36V rating aligns with your system's peak voltage transients to prevent device failure.

Selection Notes

Select this component when a single-channel high-side switch is required for loads up to 1.5A in systems powered between 4.5V and 36V. Ensure the thermal design accommodates the power dissipation at the expected load current and ambient temperature conditions.

Part Context

This part belongs to ROHM's lineup of intelligent power switches, which integrate protection circuits such as overcurrent and thermal shutdown. These devices are commonly used to replace discrete transistor solutions, simplifying PCB layout and improving reliability in power distribution networks.

Replacement Considerations

Consult ROHM's official substitution guide for direct replacements. Verify pin compatibility and electrical ratings before swapping with other high-side switches from different manufacturers.
