Dual high-side switch with 45 mOhm Rds(on) and full protection suite
The Infineon BTS52352GXUMA1 is a two-channel high-side power switch from the PROFET family, built around an N-channel vertical power MOSFET with a typical on-resistance of 45 mOhm. Each channel delivers up to 3.3 A continuous from a load supply rail spanning 4.5 V to 28 V. The switch integrates four fault-protection functions — fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping — reducing the external component count around the switch.
The BTS52352GXUMA1 carries an Obsolete lifecycle status. No official successor or replacement order code is recorded in the Infineon PROFET line.
Thermal and package fit for automotive and industrial loads
The PG-DSO-20 package (0.295-inch body width, 7.50 mm) is a surface-mount SOIC footprint with exposed pad for heat sinking. The two outputs share the common drain tab, so thermal coupling between channels is a design consideration.
On/Off interface and output behaviour
The input interface is a simple On/Off logic with a non-inverting input type. The switch does not require a Vcc/Vdd supply — it self-powers from the load rail. Auto-restart and a status flag output are included for diagnostic feedback. Output configuration is high-side with a 1:1 input-to-output ratio, meaning each of the two independent channels is controlled by its own input pin.
