Dual high-side switch with 45 mOhm Rds(on) and 3.5 A per channel
The Infineon BTS52352LAUMA1 is a dual-channel high-side power switch from the PROFET family, with two N-channel outputs each delivering up to 3.5 A and a typical on-resistance of 45 mOhm. Input logic is non-inverting with a simple On/Off interface, making it a drop-in replacement for basic high-side switching functions in body controllers, junction boxes, and relay-replacement designs.
Fault protection suite — current limit, open load, over-temp, over-voltage
The BTS52352LAUMA1 integrates fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping. The auto-restart feature means the switch attempts to re-energise after a fault clears, which is useful for transient overloads like lamp inrush or motor stall without requiring a system reset. The status flag output (open-drain) reports fault conditions to a microcontroller or logic input, allowing the system to log or respond to over-current or thermal events. This level of diagnostic feedback is typical for PROFET devices and simplifies compliance with load-monitoring requirements in automotive body modules.
Obsolete — sourcing through independent distribution
Infineon has marked the BTS52352LAUMA1 as obsolete.
