Dual high-side switch with integrated protection
The BTS52312GSXUMA1 is a dual-channel high-side power switch from Infineon's PROFET family, designed to drive resistive, inductive, or capacitive loads in automotive and industrial environments. Each of the two N-channel outputs is rated for a continuous 1.8A maximum, with a typical on-resistance of 140 mOhm max across the 4.5V to 28V load supply range. The switch integrates a full fault-protection suite: current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping. A status flag output and auto-restart feature simplify system-level diagnostics and recovery.
Package and temperature grade
The input is non-inverting with a simple On/Off interface — no external Vcc supply is required for the logic side, which keeps the BOM lean.
Now obsolete — sourcing plan needed
Infineon has marked the BTS52312GSXUMA1 as obsolete. No successor part number is listed on the official record, so a direct drop-in replacement is not guaranteed from the manufacturer. For existing designs, the last-time-buy window has closed; remaining stock is available through independent distribution. The base product number is BTS5231, which may help identify cross-reference candidates within the PROFET family that share the same SOIC-14 footprint and dual-channel high-side topology.
