Product details

Dual high-side switch for 12V/24V loads

The Infineon BTS5234LNT is a PROFET dual-channel high-side power switch in a PG-DSO-12-2 package with exposed pad. This part switches resistive, inductive, and lamp loads using an On/Off interface and non-inverting input to control two independent outputs.

Protection set and thermal range

The Auto Restart feature means the switch re-enables after a fault condition clears, which suits loads that may temporarily exceed the current threshold during inrush without requiring a system reset.

For new designs, consider the current PROFET+2 or PROFET+24V families from Infineon — these are not pin-compatible replacements but offer similar dual-channel high-side functionality with updated protection and diagnostic features. Cross-reference the pinout and package before substituting.

Frequently asked questions

What is the difference between BTS5234LNT and BTS5234L?

The suffix 'NT' typically indicates a specific packaging or tape-and-reel variant. The electrical specifications — dual high-side, 45 mOhm Rds(on), 3.5 A output, same protection set — are identical. The difference is in the shipping medium and possibly the date code range; confirm with the datasheet for exact ordering code breakdown.
