Product details

Low-side switch with integrated protection

The IPS1041LPBF is a single-channel low-side N-channel smart switch from Infineon's IPS family. It integrates a power MOSFET with current limiting and overtemperature protection, so it can drive resistive, inductive, or lamp loads without an external sense resistor or thermal fuse. Rated for a load voltage up to 28 V and a continuous output current of 1.95 A, with a typical on-resistance of 80 mOhm. The 1:1 input-to-output ratio and non-inverting input make it a straightforward on/off switch controlled by a logic-level signal — no external Vcc supply needed.

Frequently asked questions

What is the replacement for IPS1041LPBF?

Infineon does not list a direct successor for the IPS1041LPBF in the available records. For a pin-compatible alternative, check the IPS series from Infineon or a similar low-side smart switch from STMicroelectronics or NXP — confirm the package (SOT-223), Rds(on), and protection features match your BOM. We can help cross-reference against an RFQ.
