BTS5016SDAAUMA1 Overview
A high-side power switch is a semiconductor switch placed between the supply rail and the load; the switch connects the load to Vbat when activated, allowing the microcontroller ground-referenced logic to control it directly. Smart high-side switches add diagnostic feedback (load current sense) and protective functions (overcurrent, overtemperature, short-circuit, overvoltage, and reverse battery), eliminating the discrete fuse + relay + freewheeling diode + current-sense resistor chain traditionally used in body-electronics and powertrain ECUs. BTS5016SDAAUMA1 belongs to the broader category of protected MOSFET switches, hierarchically a sub-family of Power Distribution Switches within Power Management ICs.
Key features include 5.5 A nominal load current, integrated current sense, very low standby current for quiescent-sensitive body modules, current-controlled input pin for direct MCU GPIO drive, fast demagnetization of inductive loads, Reversaveā¢ reverse-polarity protection without external blocking diode, stable operation at under-voltage, and RoHS-compliant Green Product construction. The PG-TO252-5-11 DPAK package with exposed tab provides low thermal resistance (~50 C/W typical on 2 oz copper, 1 cmĀ²) for dissipating IĀ²R losses during high-current switching.
Internally, the BTS5016SDAAUMA1 uses Smart SIPMOS chip-on-chip technology that stacks the control IC on top of the vertical power MOSFET die, sharing the same package substrate. The charge pump generates the Vgs above Vbat needed to enhance the N-channel MOSFET fully, while diagnostic current-mirror cells feed the IS pin with a fraction of the load current (typically 1/2000 ratio) for the MCU's ADC to read back load health and detect open/short conditions.
Typical applications include automotive lighting (headlamps, tail lamps, turn signals, interior lighting), 12 V relay and solenoid drivers, body control modules, powertrain auxiliary outputs, and any 12 V DC load requiring diagnostic feedback and integrated protection.
When designing with this part, ensure the load's inrush current is below the part's inrush rating (typically 10x nominal for short pulses), use proper PCB thermal layout with adequate copper area on the tab, and add an external TVS or capacitor on the output if long inductive wire harnesses are present.

Typical Applications
BTS5016SDAAUMA1 is suitable for 7 applications: Automotive Headlamp and Tail Lamp Driver, 12 V Automotive Relay and Solenoid Driver, Body Control Module (BCM) Load Outputs, Powertrain Auxiliary Load Switching, LED Daytime Running Light (DRL) Driver, Industrial 24 V PLC Digital Output Module, Reverse Battery and Load-Dump Protected Distribution.
Automotive Headlamp and Tail Lamp Driver
The BTS5016SDAAUMA1's 5.5 A continuous current rating and fast demagnetization of inductive loads make it a strong fit for driving 12 V automotive headlamp and tail-lamp bulbs. Per the Infineon Classic PROFETā¢ 12V datasheet, the integrated charge pump fully enhances the N-channel MOSFET for low RDS(on) and minimal steady-state power dissipation; the load current sense pin (IS) lets the BCM detect open-filament faults, while Reversaveā¢ reverse-polarity protection eliminates an external blocking diode on the lamp return path.
Recommended
12 V Automotive Relay and Solenoid Driver
The BTS5016SDAAUMA1 is designed to drive 12 V automotive relays and solenoids in body and powertrain ECUs, where its 5.5 A rating comfortably covers typical coil currents and its current-controlled input pin accepts direct 3.3 V or 5 V MCU GPIO drive without level shifting. The integrated fast inductive-load demagnetization handles the back-EMF that occurs when the relay coil de-energizes, replacing discrete flyback diodes and reducing PCB area. The exposed tab of the PG-TO252-5-11 package dissipates the relay inrush with a properly sized copper pour.
Recommended
Body Control Module (BCM) Load Outputs
The BTS5016SDAAUMA1 belongs to Infineon's Classic PROFETā¢ 12V family and is widely deployed in automotive body control modules for switching miscellaneous 12 V loads such as interior lighting, seat heaters, mirror heaters, and accessory sockets. Its very low standby current is critical for quiescent-sensitive body modules where parasitic drain must stay below 100 uA per channel. The integrated current sense (IS) pin enables the BCM firmware to perform open-load, short-to-ground, and overcurrent diagnostics in real time.
Recommended
Powertrain Auxiliary Load Switching
The BTS5016SDAAUMA1 is suitable for powertrain auxiliary loads such as fuel pump relays, EGR solenoids, purge valves, and coolant pump drivers where 12 V supply switching with diagnostic feedback is required. The part's improved EMC performance minimizes conducted and radiated emissions that could couple into adjacent sensor signal chains, and its stable under-voltage behavior prevents undefined output states during cranking transients. The exposed-tab PG-TO252-5-11 package handles the thermal load under-hood.
Recommended
LED Daytime Running Light (DRL) Driver
The BTS5016SDAAUMA1 can drive LED daytime running light strings from a 12 V automotive bus, with the current-controlled input pin enabling PWM dimming directly from the BCM GPIO without additional driver circuitry. The integrated overcurrent and overtemperature protection of the Classic PROFETā¢ 12V family guards the LED string against wiring faults. For higher LED string voltages, an external boost stage can be added upstream, but for direct 12 V LED strings the part's 5.5 A rating comfortably covers typical 5-30 W DRL modules.
Recommended
Industrial 24 V PLC Digital Output Module
Although the BTS5016SDAAUMA1 is qualified for 12 V automotive rails, its robust protection features and integrated current sense also make it suitable for industrial 24 V PLC digital-output modules driving solenoids, valves, and indicator lamps. The current-controlled input accepts 3.3 V or 5 V logic-level signals from a PLC backplane, the load current sense output enables per-channel fault detection, and the PG-TO252-5-11 package provides industrial-grade thermal performance. Verify the absolute maximum Vbat rating against the industrial 24 V rail tolerances before deployment.
Recommended
Reverse Battery and Load-Dump Protected Distribution
The BTS5016SDAAUMA1's Reversaveā¢ reverse-polarity protection and integrated load-dump clamping make it an ideal building block for protected 12 V power distribution nodes in safety-critical automotive ECUs. The exposed tab of the PG-TO252-5-11 package can be soldered to a copper bus bar for high-current distribution. The combination of overcurrent, overtemperature, short-to-ground, and reverse-battery protection in one IC replaces several discrete protection components and reduces PCB area and BOM cost.

Design Notes
Estimated: At 5.5 A continuous load with RDS(on) of approximately 30 mOhm (typical for this family), conduction loss is roughly 0.9 W. The PG-TO252-5-11 DPAK package on 1 cmĀ² of 2 oz copper has a typical theta_JA around 50 C/W, yielding a junction temperature rise of ~45 C above ambient at full load. For sustained 5.5 A operation at 85 C ambient, enlarge the copper pour to at least 2 cmĀ² to keep Tj below 150 C. The exposed tab must be soldered to the copper pour for thermal dissipation - do not leave it floating.
Place the BTS5016SDAAUMA1 close to the connector to minimize the length of the high-current output trace, which can carry 5.5 A in steady state and several times that during inrush. Use a wide trace (at least 50 mil for 5 oz copper, or pour directly into the tab) from the OUT pin to the load, and keep the IS trace short and routed away from switching nodes to avoid capacitive coupling that corrupts the current-sense signal. Add a 100 nF ceramic bypass capacitor close to the Vbat pin and a reverse-polarity TVS if load-dump transients exceed the part's Vbat(AZ) rating.
Do not drive the IN pin with a voltage source directly - it is a current-controlled input designed for a series resistor from the MCU GPIO (typically 1-10 kOhm depending on desired switching speed). Do not exceed the part's inrush SOA: cold incandescent filaments and capacitive loads can draw 10x nominal at turn-on. Do not leave the IS pin floating if unused - tie it to GND through a resistor to prevent noise injection. Always confirm absolute maximum Vbat rating against the vehicle's load-dump profile (ISO 7637-2).
The exposed tab of the PG-TO252-5-11 package is the drain/output node and must be soldered to the PCB copper pour for both thermal dissipation and electrical connection. Use thermal vias under the tab (typically an array of 4-9 vias, 0.3 mm drill, 1 mm pitch) to conduct heat to inner copper layers. Keep high-current output traces on the top layer or on inner planes directly under the tab. Avoid running sensitive analog signal traces (such as the IS current-sense return) directly under switching nodes to minimize coupling.
