BSP452

BSP452 Description

The BSP452 by Infineon Technologies is a high-side power switch from the Classic PROFET series, designed for automotive and industrial applications requiring robust current control. This AEC-Q100 compliant device integrates a 1.5A current limit, 200mΩ max on-resistance, and operates within a 5V to 34V input range, delivering up to 700mA output current. Housed in a 4-pin (3+Tab) SOT-223 package, it features surface-mount compatibility, 1.8W power dissipation, and a 150°C max operating temperature, making it ideal for harsh environments. Its PROFET technology ensures reliable load switching with built-in protection against overload, overtemperature, and short circuits.

BSP452 Features

• High-Side Switch: Single 1-IN/1-OUT configuration with 160mΩ typical on-resistance for minimal power loss.
• Wide Voltage Range: Supports 5V to 34V input, compatible with 12V/24V automotive systems.
• Robust Protection: Integrated current limiting (1.5A), overtemperature shutdown, and fast fault response (100µs max on/150µs off time).
• Automotive-Grade: AEC-Q100 qualified, EU RoHS/ROHS compliant, and moisture-sensitive (MSL1).
• Compact & Efficient: SOT-223 package (6.5x3.5x1.6mm) with tab for enhanced thermal dissipation.

BSP452 Applications

• Automotive Load Control: Ideal for LED lighting, relay drivers, and seat/window heating modules.
• Industrial Systems: Powers solenoids, actuators, and small motors in PLCs and automation.
• Diagnostic Ports: Safely manages OBD-II or CAN bus power supply with fault reporting.
• Battery Management: Protects low-voltage circuits in 12V/24V battery systems from overloads.

Conclusion of BSP452

The BSP452 combines high reliability, compact design, and advanced protection for demanding applications. Its low on-resistance, wide operating voltage, and automotive certification make it superior to generic switches, particularly in space-constrained, high-temperature environments. A versatile solution for power distribution and load switching in automotive, industrial, and consumer electronics.
