BSP452HUMA1

BSP452HUMA1 Description

The BSP452HUMA1 from Infineon Technologies is a high-performance N-channel power switch designed for high-side load switching applications. Part of the miniPROFET® series, this surface-mount device integrates a 1:1 ratio MOSFET driver with robust fault protection, making it ideal for demanding automotive, industrial, and consumer electronics. It operates over a 5V to 34V load voltage range and delivers up to 700mA continuous current with a low Rds(on) of 160mOhm (typical), ensuring efficient power management. The device requires no external supply voltage (Vcc/Vdd), simplifying system design. Packaged in SOT223-4 and available in tape & reel, it meets ROHS3 and REACH compliance, with an MSL3 rating for extended shelf life.

BSP452HUMA1 Features

• High-Side Configuration: Enables direct control of grounded loads, reducing wiring complexity.
• Integrated Protections: Combines fixed current limiting, over-temperature shutdown, and over-voltage clamping for enhanced reliability.
• Low Power Dissipation: Optimized 160mOhm Rds(on) minimizes heat generation, improving efficiency.
• Wide Voltage Range: Supports 5V to 34V loads, versatile for 12V/24V systems.
• No Vcc/Vdd Required: Eliminates need for auxiliary power, reducing BOM cost.
• Automotive-Grade Robustness: Suitable for harsh environments with AEC-Q100 qualifications (implied by miniPROFET® series).
• Compact SOT223-4 Package: Space-saving footprint for high-density PCB designs.

BSP452HUMA1 Applications

• Automotive Systems: ECU load switching, LED lighting, and motor control in 12V/24V architectures.
