Typical Applications
BTS52004EKAXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), LED Lighting Modules (Interior and Exterior), Industrial 24 V PLC Output Modules, HVAC Actuator and Damper Control, Solenoid and Relay Driver Bank, Battery-Powered Equipment Switching.
Automotive Body Control Module (BCM)
The BTS52004EKAXUMA1's four 800 mA high-side channels and 38 V load-dump tolerance make it ideal for automotive BCMs driving turn signals, mirror heaters, interior lamps, and small solenoids. Each channel's integrated short-circuit, overtemperature, and open-load protection satisfies AEC-Q100 body-electronics reliability targets. The IS pin delivers proportional load current back to the BCM microcontroller for bulb-out detection and fault logging. Compared to four discrete MOSFETs, the BTS52004EKAXUMA1 reduces PCB area by ~70% and eliminates the need for an external charge pump, gate driver, and current-sense resistor network on every channel. The exposed thermal pad spreads heat across the body-control PCB copper pour, sustaining full 800 mA per channel at 85 °C ambient.
Recommended
LED Lighting Modules (Interior and Exterior)
Four independent PWM-controlled channels at up to 1 kHz let the BTS52004EKAXUMA1 drive RGBW interior ambient lighting, daytime running lights, or rear combination lamps directly from a 12 V automotive bus. The 200 mΩ on-resistance minimizes thermal dissipation: at 500 mA LED current each channel drops only 0.1 V, leaving 0.25 W of waste heat per channel - well within the PG-DSO-14-48-EP thermal envelope. The IS pin supports LED open-circuit and short-to-GND diagnostics, enabling the body controller to flag failed pixels in compliance with automotive functional-safety requirements. Compared to discrete N-MOSFET plus sense-resistor designs, the BTS52004EKAXUMA1 saves PCB area and BOM cost per lighting node.
Recommended
Industrial 24 V PLC Output Modules
The 5–38 V operating range and 200 mΩ Ron suit the BTS52004EKAXUMA1 to 24 V industrial PLC discrete-output cards driving solenoid valves, relay coils, and indicator lamps. Each channel's integrated short-circuit protection allows direct connection to capacitive or inductive field wiring without external fuses. The IS pin provides 4–20 mA-style proportional load current feedback to the PLC backplane, enabling predictive maintenance for stuck valves or failing lamps. Compared to electromechanical relays, the BTS52004EKAXUMA1 offers >10⁹ switching cycles and <1 ms response time, ideal for high-cycle industrial automation. The PG-DSO-14-48-EP exposed-pad package simplifies thermal design on the PLC output card.
Recommended
HVAC Actuator and Damper Control
In HVAC systems, the BTS52004EKAXUMA1 drives four small DC motors for zone dampers, blend doors, and recirculation flaps. The 1 kHz PWM capability supports soft-start ramps that reduce acoustic noise from the damper motors. Integrated short-circuit and overtemperature protection survives stall conditions when a damper jams, automatically shutting down and auto-restarting after the fault clears. The IS pin enables the climate controller to detect end-stop positions by sensing motor current rise, simplifying mechanical limit-switch wiring. With 38 V load-dump tolerance, the BTS52004EKAXUMA1 operates directly from the 24 V industrial HVAC bus without additional protection.
Recommended
Solenoid and Relay Driver Bank
Each of the four channels can drive an inductive load up to 800 mA, making the BTS52004EKAXUMA1 suitable for solenoid valves, fuel injectors, and small relay coils in equipment-control systems. The integrated charge pump and flyback energy handling simplify the BOM compared to discrete MOSFET plus flyback diode solutions. The IS pin monitors solenoid current for closed-loop force control in proportional valves. Operating from -40 °C to +150 °C junction temperature, the device handles underhood and outdoor industrial enclosures without derating. Compared to a discrete high-side switch design, the BTS52004EKAXUMA1 reduces PCB area by ~60% and improves diagnostic coverage at lower BOM cost.
Recommended
Battery-Powered Equipment Switching
The BTS52004EKAXUMA1's low standby current and 5–38 V supply range suit it to battery-powered equipment such as e-bike controllers, portable medical pumps, and telecom backup-power units switching auxiliary loads. Four protected outputs let one IC replace four mechanical switches or relays, reducing BOM cost and improving reliability in vibration-prone portable equipment. The exposed pad enables PCB copper heatsinking without a discrete heatsink, keeping the design compact. The IS pin provides real-time load-current telemetry to a battery-monitoring MCU, supporting accurate state-of-charge estimation. According to the Infineon datasheet, the integrated reverse-battery protection simplifies the input protection network.

Key Differentiators
- Four independent 200 mΩ high-side channels in one PG-DSO-14-48-EP package (vs Four discrete N-channel MOSFETs plus gate drivers)
- Integrated proportional current sense (IS pin) per channel (vs BTS118DATMA1 (no IS pin))
- 200 mΩ on-resistance balances thermal dissipation and channel count (vs BTS70082EPAXUMA1 (8 mΩ, single channel, ~$2.20))
Design Notes
At full-load 800 mA on all four channels from a 12 V supply, the BTS52004EKAXUMA1 dissipates 4 × (200 mΩ × 0.8²) ≈ 0.51 W. From a 24 V supply driving 0.5 A per channel the dissipation rises to 4 × (200 mΩ × 0.5²) ≈ 0.20 W. The PG-DSO-14-48-EP exposed pad must be soldered to at least 2 cm² of copper per channel for sustained 800 mA operation at 85 °C ambient. Estimated junction-temperature rise with 6 cm² total copper on a 4-layer 1 oz PCB is ~30 K above ambient; verify with the datasheet thermal table before finalizing layout.
Place a 100 nF ceramic decoupling capacitor directly at the Vbb pin (pin 9) and a 10 µF electrolytic or ceramic bulk capacitor within 5 mm of the pin to suppress load-dump transients and stabilize the internal charge pump. The IS pin requires a ground-referenced sense resistor (typically 1 kΩ); keep the IS trace short and away from switching nodes. Connect the exposed pad to a top-layer copper pour stitched with thermal vias to inner ground planes for optimal heat spreading. All four OUT pins need short, wide traces (≥0.5 mm per 100 mA) to limit voltage drop and copper heating.
Do not operate the BTS52004EKAXUMA1 below 5 V on Vbb - the internal charge pump cannot sustain gate drive and Ron rises sharply, causing thermal runaway. Do not drive highly inductive loads (>10 mH) without external freewheeling protection; the internal avalanche clamp handles modest inductance but not large relay or solenoid coils. Always verify the latest datasheet revision - Infineon occasionally revises protection thresholds and IS-pin ratios between silicon revisions. Do not connect IS pin directly to an ADC input without the recommended sense resistor; the IS pin is a current source, not a voltage output.
Route the four IN logic inputs as a parallel bus from the MCU with a single 10 kΩ pull-down per line to guarantee defined off-state during MCU reset. Keep the IS trace away from OUT1–OUT4 switching copper to avoid capacitive coupling that distorts the sense signal at high di/dt. Place the exposed pad on a continuous top-layer copper pour stitched with an array of 0.3 mm thermal vias on a 1 mm pitch to inner ground planes. According to Infineon PROFET application notes, ground the IS sense resistor directly to the device GND pin (pin 11), not to a distant system ground, to avoid ground-loop error in the current-sense signal.
