Product details

Four-channel high-side switch for 12V/24V distribution

The Infineon BTS52004EKAXUMA1 is a PROFET N-channel high-side power switch with four independent outputs, each rated for 800 mA continuous and a typical on-resistance of 200 mOhm. The load voltage range spans 5 V to 28 V, which covers both 12 V automotive and 24 V industrial rails without a separate supply bias — Vcc is not required.

Junction temperature and package — the thermal budget

The 14-SOIC exposed pad package (PG-DSO-14-48-EP) requires a thermal-via stitch to the ground plane to pull heat out of the die; without it, the 800 mA per-channel rating derates significantly above 85°C ambient.

Protection set saves downstream components

Fixed current limiting clamps each channel at a safe level during a short to ground — the 200 mOhm Rds(on) limits the inrush current on a cold lamp or capacitive load without external series resistors. Open-load detection flags a disconnected harness or blown fuse, and over-temperature protection latches the channel off until the die cools. These features are built into the parallel interface; no SPI or diagnostic bus is needed, which simplifies the MCU firmware for a simple on/off load bank.

Lifecycle and sourcing — no LTB pressure

The part is ROHS3 compliant.

Frequently asked questions

What is the Rds(on) of BTS52004EKAXUMA1?

The typical on-resistance is 200 mOhm per channel at nominal operating conditions. This value drives the power dissipation — at 800 mA, expect about 128 mW per channel in the steady state, which sums to 512 mW across all four outputs. The actual junction temperature rise depends on the board's thermal-via layout under the exposed pad.

What is the maximum output current per channel for BTS52004EKAXUMA1?

Each of the four channels is rated for 800 mA maximum continuous output current. The total load budget is 3.2 A, but the 14-SOIC exposed pad package limits the practical continuous sum — thermal derating applies above 85°C ambient, and the junction must stay under 150°C. For a 12 V rail at 800 mA per channel, the 200 mOhm Rds(on) dissipates about 128 mW per channel; four channels at full load produce roughly 512 mW of heat that must be conducted through the exposed pad.

Is BTS52004EKAXUMA1 obsolete?

No — the lifecycle status is Active, meaning Infineon is still manufacturing the part with no announced discontinuation. ROHS3 compliant. No last-time-buy pressure for current production runs.

What is the closest functional equivalent to BTS52004EKAXUMA1?

The BTS142DATMA1 is a single-channel low-side switch in the HITFET series with 23 mOhm Rds(on) and 4.6 A output, but it is a different output configuration (low-side vs high-side) and a single channel. For a four-channel high-side replacement within the PROFET family, the BTS52004EKAXUMA1 has no direct pin-compatible second source — the closest functional match is Infineon's own PROFET portfolio with similar channel count and Rds(on) range, but each variant differs in package and protection set. Verify the footprint and diagnostics before substituting.

What package is BTS52004EKAXUMA1 in?

The part is supplied in a 14-SOIC (0.154", 3.90 mm width) package with an exposed pad, Infineon's designation PG-DSO-14-48-EP. The exposed pad is the drain connection and the primary thermal path. Mounting is surface-mount. Tape & Reel and Cut Tape options are available.
