BTS5016SDA Overview
A smart high-side switch (also called a high-side driver, intelligent power switch, or PROFET) is a semiconductor device that connects a load to the positive supply rail and integrates overcurrent, overvoltage, overtemperature, and short-circuit protection together with diagnostic feedback. High-side switches sit hierarchically within the power distribution family, which itself belongs to the broader power management integrated circuit (PMIC) category. By replacing discrete fuses, relays, and MOSFET driver circuitry, they reduce PCB area and improve system reliability in automotive and industrial 12 V systems.
The BTS5016SDA provides a defined fault signal during overload, overtemperature, or short-circuit events, enabling the microcontroller to take protective action. Its load current sense pin delivers a proportional analog current that the host ECU can read via an ADC for diagnostics and load monitoring. The device operates across an input voltage range of approximately 4.5 V to 16 V and offers very low standby current, making it well suited to permanently wired battery applications that must meet stringent quiescent current budgets.
The internal architecture uses a charge pump to drive the N-channel MOSFET gate above the battery rail, achieving a low typical R_DS(on) of around 16 mΩ at room temperature. This low on-resistance minimizes conduction losses and thermal rise during high-current load switching, allowing compact DPAK PCB layouts without forced cooling. The integrated reverse-battery protection (Reversave™) and EMC optimization further simplify compliance with automotive EMC standards.
Typical applications include automotive body and lighting loads, including LED daytime running lights, tail lamps, seat heaters, mirror heaters, and small DC motor drivers. The diagnostic feedback and protective features also suit industrial 12 V/24 V systems such as solenoid and valve control.
When designing with the BTS5016SDA, place a reverse-polarity protection element on the supply side if the system must survive double-battery jump-start events, and ensure the exposed pad is soldered to a sufficient copper pour for heatsinking. Always reference the device's load current sense resistor value in the datasheet to scale the analog diagnostic current correctly for your ADC reference voltage.

Typical Applications
BTS5016SDA is suitable for 6 applications: Automotive LED Daytime Running Lights, Automotive Tail Lamp and Turn Signal Switch, Seat Heater and Mirror Heater Control, Solenoid and Valve Driver (Industrial 12/24 V), Body Control Module (BCM) High-Side Output, Small DC Motor and Blower Driver.
Automotive LED Daytime Running Lights
The BTS5016SDA is well suited to driving automotive LED daytime running lights (DRLs) directly from the 12 V battery rail. Its 16 mΩ typical R_DS(on) keeps conduction loss under 0.5 W at 5.5 A, allowing the DPAK-5 package to dissipate the heat without forced cooling on a standard FR-4 PCB. The integrated load current sense output lets the body-control ECU monitor LED health in real time, while overtemperature and short-circuit shutdown protect against harness faults. Compared to a discrete MOSFET plus fuse solution, the BTS5016SDA cuts PCB area and improves reliability by replacing the fuse with a resettable intelligent switch.
Recommended
Automotive Tail Lamp and Turn Signal Switch
Tail lamps and turn signals draw 2-5 A and require fault detection to alert the driver to bulb failure. The BTS5016SDA's load current sense output delivers a proportional analog current that an ECU ADC can read for open-load and short-to-ground detection, satisfying FMVSS 108 functional requirements. Its 5.5 A continuous rating covers incandescent, halogen, and modern LED tail lamps with margin. With AEC-Q100 qualification and a -40 °C to +150 °C junction range, the device operates reliably in the harsh thermal environment of an automotive rear lamp housing.
Recommended
Seat Heater and Mirror Heater Control
The BTS5016SDA drives resistive heating loads such as seat heaters and side-mirror heaters at up to 5.5 A from a 12 V battery. The PWM-capable input pin allows closed-loop temperature control via duty-cycle modulation, while the diagnostic sense output monitors current draw for fault detection. The Reversave™ reverse-battery feature protects the heater load during a wiring fault or jump-start event. Compared to electromechanical relays, the BTS5016SDA eliminates audible clicking, reduces EMI, and extends system lifetime by removing moving contacts.
Recommended
Solenoid and Valve Driver (Industrial 12/24 V)
The BTS5016SDA drives small 12 V / 24 V solenoids and proportional valves in industrial process control and building automation, where its 5.5 A continuous rating covers most coil currents and its diagnostic feedback reports stuck-valve conditions to the PLC. The exposed pad of the PG-TO252-5-11 package allows sufficient thermal dissipation for duty-cycled loads up to 50 percent, while overtemperature shutdown protects against continuous-on faults. The current-controlled input works directly with 3.3 V and 5 V logic, simplifying interface to a wide range of industrial microcontrollers.
Recommended
Body Control Module (BCM) High-Side Output
The BTS5016SDA serves as a single high-side output driver inside an automotive body control module, controlling accessories such as interior lamps, horn, and wipers. Its 16 mΩ typical R_DS(on) keeps the BCM thermal budget manageable, and its integrated fault feedback reduces wiring complexity by reporting open-load and short-circuit events over a single diagnostic pin. AEC-Q100 qualification allows direct use in body and chassis ECUs without additional qualification cycles. Multiple BTS5016SDA devices can be paralleled across different loads with their fault outputs feeding a single ADC multiplexer.
Recommended
Small DC Motor and Blower Driver
The BTS5016SDA can drive small brushed DC motors such as HVAC blower fans, mirror adjusters, and headlight leveling actuators at currents up to 5.5 A. The PWM-capable input allows variable-speed control, and the diagnostic sense pin reports stall conditions for motor protection. The integrated short-circuit shutdown reacts in microseconds to a stalled rotor, protecting the wiring harness from fire hazards. Compared to a relay plus diode approach, the BTS5016SDA provides silent, software-controlled operation with full diagnostic feedback.

Key Differentiators
- Highest current class within the BTS5016 family at exactly the same footprint (vs BTS5010-1EKA)
- Lower R_DS(on) than lower-tier family members (vs BTS5010-1EKA)
- Pin-to-pin compatible within Classic PROFET 12V family for BOM flexibility (vs BTS5020-1EKA / BTS5045-1EKA)
- Integrated Reversave™ reverse-battery protection (vs Generic third-party high-side switches without reverse-battery protection)
Design Notes
Estimated: at 5.5 A continuous load and 16 mΩ typical R_DS(on), the BTS5016SDA dissipates roughly 0.5 W in the on-state (P = I² × R). Combined with switching losses and reverse-battery clamping, the steady-state dissipation in a 12 V automotive seat-heater application typically reaches 1-2 W. The PG-TO252-5-11 exposed pad must be soldered to at least 1 square inch of 2 oz copper to keep junction temperature rise below 50 °C above ambient; without proper PCB copper the device will trigger overtemperature shutdown well before reaching its 5.5 A rating.
Do not forget the input current-limiting resistor on the IN pin — the BTS5016SDA uses a current-controlled input, not a voltage input. Per the Infineon datasheet, the input pin requires a series resistor sized so that the logic-high input current stays within the recommended range (typically 1-3 mA). Driving the IN pin directly from a 3.3 V or 5 V GPIO without the resistor will mis-bias the internal charge pump and may cause partial turn-on or excessive input current.
Place a reverse-polarity protection element (Schottky diode or P-channel MOSFET) on the Vbb supply if the harness can be mis-wired during service. The BTS5016SDA's internal Reversave™ protects the load, but the device itself still draws current from a reversed battery rail. Add a 100 nF ceramic bypass capacitor close to the Vbb pin and a 10 µF bulk capacitor on the supply rail to suppress load-dump and jump-start transients that exceed 16 V.
The load current sense output (DEN/ST pin) is an analog current source that should be read by a microcontroller ADC through an external sense resistor to ground. Keep the sense trace short and away from switching signals such as PWM inputs and inductive load traces. Add a small RC filter (10 kΩ + 100 nF) on the sense line if the load is PWM-switched to average the current-sense output and reduce noise pickup on the ADC input.
