Infineon BSP742R Series Power Switch IC, 1.5W Power Rating, 34V Maximum Supply Voltage - BSP742RXUMA1
This power switch IC is a high-side device designed for automotive loads, providing controlled switching of multiple channels within vehicle electrical systems. It operates across a typical vehicle supply range and is built for surface-mount assembly in compact electronic modules, offering multi-output switching suitable for distributed loads and input-controlled load management.
Features and Benefits:
• Operates from 5V to 34V supply for wide voltage tolerance
• Handles 0.4A operating current per channel to drive moderate loads
• 700mΩ Rds(on) minimises conduction losses during operation
• 1.5W power rating supports continuous dissipation within limits
• Temperature range -40°C to 150°C enables harsh-environment operation
• Handles 0.4A operating current per channel to drive moderate loads
• 700mΩ Rds(on) minimises conduction losses during operation
• 1.5W power rating supports continuous dissipation within limits
• Temperature range -40°C to 150°C enables harsh-environment operation
Applications
• Suitable for body control modules managing lighting circuits
• Ideal for fan and small motor switching in climate systems
• Used for multiplexed power distribution to sensors and actuators
• Can be used for accessory load switching in compact control units
• Used with surface-mount assemblies in space-constrained modules

How many switching outputs does it provide and how are they arranged?
It offers five independent outputs driven from a single input control, enabling centralised control of multiple loads in one package.
What package and mounting considerations are there for PCB design?
The device is supplied in an 8-pin DSO surface-mount package, allowing low-profile placement and standard solder reflow processes for compact board layouts.
What thermal environment can it withstand during operation?
It is specified to operate across a minimum of -40°C up to a maximum of 150°C, suitable for elevated under-hood temperatures when mounted with appropriate PCB thermal management.
What electrical constraints should be observed for safe use?
Ensure the supply voltage remains between 5V and 34V and that per-channel current does not exceed 0.4A, with power dissipation managed to remain within a 1.5W limit.
