Infineon BSP452 Series Power Switch IC, 40V Maximum Supply Voltage, 0.2Ω Switch On Resistance Rds On - BSP452HUMA1
This power switch IC provides controlled high-side switching for automotive electronic systems, designed for use in AEC-compliant environments. It offers multiple outputs and a single control input to manage power distribution in vehicle subsystems while operating across a wide automotive temperature range.
Features and Benefits:
• 40V maximum supply voltage enables robust system tolerance
• 0.2 Ω Rds(on) minimises conduction losses for efficiency
• 1.6 mA quiescent current reduces standby power draw
• 1.8W power rating handles moderate continuous dissipation
• 4-pin SOT-223 surface-mount package simplifies PCB assembly
• 0.2 Ω Rds(on) minimises conduction losses for efficiency
• 1.6 mA quiescent current reduces standby power draw
• 1.8W power rating handles moderate continuous dissipation
• 4-pin SOT-223 surface-mount package simplifies PCB assembly
Applications
• Suitable for lighting module power distribution
• Ideal for switching loads in body electronics
• Used with sensor clusters requiring multiple outputs
• Can be used for auxiliary power control circuits
• Ideal for switching loads in body electronics
• Used with sensor clusters requiring multiple outputs
• Can be used for auxiliary power control circuits
How many control and switched lines does it provide?
It accepts one input control and distributes switching across five separate outputs, allowing centralised command of multiple loads.
What thermal limits should designers consider?
The device is rated to operate between -40 °C and 150 °C, so thermal management on the board should account for elevated ambient under the vehicle bonnet conditions.
What mounting and footprint considerations apply?
It is supplied in a SOT-223 style 4-pin surface-mount package measuring a 6.5 x 3.5mm footprint with 1.6mm component height, suitable for automated soldering processes.
What topology and switch type does it implement?
It functions as a high-side power switch topology, providing switched positive-supply control for downstream loads.
