BTS6163DAUMA1 概要
A high-side switch (HSS) is a power-distribution topology where the load is tied to ground and the FET switches the positive supply rail. In the BTS6163D family, Infineon's Smart SIPMOS chip-on-chip technology combines the power stage and control die in a single package, delivering embedded protective functions and optimized static electromagnetic compatibility (EMC) without external compensation components. This integration places the part in the broader category hierarchy: high-side switch -> power distribution switch -> load driver -> PMIC -> power management IC -> semiconductor.
Key features include 21.5 A continuous current capability, 20 mOhm typical on-resistance, integrated charge pump, current sense diagnostic output, overtemperature shutdown, overvoltage protection (including load-dump), short-circuit protection with auto-restart, open-load detection both in on-state and off-state, ground-loss detection, and reverse-battery robustness via an integrated reverse-protection diode. The diagnostic feedback pin provides both a digital status flag and an analog load-current sense proportional to the drain current.
Architecturally, the BTS6163DAUMA1 uses a charge-pump-driven N-channel vertical MOSFET for low RDS(on) despite the high-side configuration, while the analog/digital mux on the IS pin lets the MCU read load current and fault status through a single wire. This dramatically reduces BOM and wiring complexity in body-electronics modules.
Typical applications include automotive body control modules (lighting, seat heating, mirror adjustment), industrial PLC outputs, 24 V truck and agricultural-vehicle load switching, and any system requiring protected high-side switching with load diagnostics. The wide 5.5 V to 62 V input range supports both 12 V passenger-vehicle and 24 V commercial-vehicle buses, while the integrated protections eliminate the need for external fuses or TVS diodes in most designs.
When designing with this part, place a reverse-protective input capacitor of at least 100 nF directly at the Vbb pin and ensure the IS sense resistor is sized so the diagnostic current does not exceed the ADC input range during maximum load. The exposed tab (PG-TO252-5-11) provides the primary thermal path and must be soldered to a copper pad of at least 6 cm^2 for full 21.5 A operation.

主な用途
BTS6163DAUMA1 の用途: 7 件s: Automotive Body Control Modules - Lighting, Industrial PLC Digital Outputs, 24V Commercial Vehicle Load Switching, Power Distribution and Fuse Replacement Modules, Motor and Solenoid Drivers, Heated Seat and Cabin Comfort Modules, Battery-Connected LED Lighting Drivers.
Automotive Body Control Modules - Lighting
The BTS6163DAUMA1 is well-suited for driving automotive exterior and interior lamps (headlamp ballasts, DRLs, brake/tail lamps) from a body control module. Its 21.5 A continuous rating covers high-power halogen or LED matrices that exceed 10 A, while the 20 mOhm RDS(on) keeps cold-crank voltage drop on the lamp cable under 0.5 V at full load. Integrated short-circuit auto-restart handles the wiring-harness fault case (chafed cable short to ground) without blowing a fuse, and the analog current-sense pin lets the BCM distinguish 'lamp off' from 'open load' for end-of-line diagnostics. Place a 100 nF ceramic bypass at Vbb and a 10 kohm resistor on IS for current sense.

Industrial PLC Digital Outputs
In industrial 24 V PLC digital-output modules the BTS6163DAUMA1 replaces a discrete high-side MOSFET plus fuse plus protection network. Its 5.5 V to 62 V Vbb range tolerates industrial 24 V plus supply transients, and the multiplexed analog current sense on the IS pin lets the PLC detect wire-break, short-circuit, and overload per-channel without extra op-amps. With 21.5 A continuous, one channel can drive solenoid banks or motor starters in the <2 HP range. The PG-TO252-5-11 footprint simplifies multi-channel PCB layouts where 8-32 switches share a copper heat-sink bus bar. Designers should derate per channel by at least 30% for 8-channel simultaneous operation.
おすすめ
24V Commercial Vehicle Load Switching
For 24V truck, bus, agricultural, and construction-equipment electrical systems, the BTS6163DAUMA1's 62 V Vbb maximum and integrated load-dump protection are decisive advantages over 12V-only parts. The same part drives trailer tail-lamp modules, hydraulic solenoid banks, and HVAC damper motors without external TVS diodes. Its 20 mOhm RDS(on) keeps steady-state dissipation manageable for always-on loads like telematics gateway power; the IS pin enables predictive maintenance by reporting gradual load-current drift. Reverse-battery protection means no inline Schottky is needed, saving both cost and forward drop.
おすすめ
Power Distribution and Fuse Replacement Modules
The BTS6163DAUMA1 enables solid-state power distribution modules that replace legacy ATO-blade fuses in junction boxes. Each channel provides programmable current limiting via the IS pin (analog sense), resettable short-circuit behavior, and per-channel diagnostics over a shared ADC - functions impossible with a fusible link. At 21.5 A it covers the largest standard ATO fuse class; multiple BTS6163DAUMA1 in parallel can build a programmable 43 A or 65 A smart distribution module. The PG-TO252-5-11 footprint with thermal tab supports >10 W steady-state dissipation on a modest copper pour.
おすすめ
Motor and Solenoid Drivers
Small DC motors, valve solenoids, and proportional valves in 12 V/24 V systems are well-served by the BTS6163DAUMA1, which handles inrush currents of several times the steady-state value via its short-circuit auto-restart. The 20 mOhm RDS(on) limits cold-crank drop on the motor cable; integrated flyback handling protects against the inductive kick when the solenoid is de-energized. The IS pin provides bidirectional current sense, allowing closed-loop control of proportional valves. Designers must respect SOA during stalled-rotor (locked-rotor) conditions and add external TVS if the inductance is high.
おすすめ
Heated Seat and Cabin Comfort Modules
Heated seats, steering-wheel heaters, and seat-ventilation blowers draw 5-15 A per channel in automotive comfort modules, making the BTS6163DAUMA1 an ideal high-side driver. Its low 20 mOhm RDS(on) keeps seat-cable losses small so the heating element sees near-battery voltage at full power; the multiplexed IS feedback lets the climate-control ECU detect heater-element failure and warn the driver. Integrated overtemperature shutdown protects the seat foam if the heater shorts to a higher-power element. The PG-TO252-5-11 footprint supports 4-8 switches in one compact comfort-module PCB.
おすすめ
Battery-Connected LED Lighting Drivers
High-brightness LED arrays for off-road, agricultural, or emergency-vehicle lighting draw 5-20 A at 12 V or 24 V, directly matching the BTS6163DAUMA1's 21.5 A continuous rating. Its 62 V load-dump tolerance protects the LED string from transient overvoltages that would otherwise require an external TVS. The IS pin enables thermal-foldback control by reporting actual LED current to a microcontroller, which can throttle PWM duty when the LED junction temperature exceeds its limit. Reverse-battery protection eliminates the need for a series Schottky, raising overall driver efficiency.

設計ノート
Estimated: at 21.5 A load with RDS(on) of 20 mOhm, steady-state conduction loss in the FET is approximately 9.2 W. The PG-TO252-5-11 package dissipates this primarily through the exposed tab; solder the tab to a copper pad of at least 6 cm^2 on a 1 oz copper PCB to keep junction temperature below 150 C. For multi-channel designs (e.g., 4x BTS6163DAUMA1), distribute the heat by spreading copper pours or use a small aluminum heatsink clamped to the tabs.
Place a 100 nF X7R ceramic bypass capacitor directly at the Vbb pin (within 5 mm) and a 10 kohm resistor on the IS pin to ground. The IS resistor converts the analog current-sense current (typically 1/1000 of load current) into a 0-5 V signal for the MCU ADC; size it so the maximum IS voltage at 21.5 A load stays below the ADC reference. Keep the IS trace short and away from switching nodes to avoid noise coupling into the diagnostic signal.
Do not exceed 62 V on Vbb, even briefly; load-dump pulses on 24 V systems can reach 36 V steady-state and 62 V transient, so verify the supply-side TVS or rely on the part's integrated load-dump clamp. Never drive the load from the BTS6163DAUMA1 in parallel with another switch without a current-balancing resistor or external ORing - the part's RDS(on) tolerance allows dangerous circulating currents. The IN pin is CMOS-compatible but must be driven rail-to-rail; leaving it floating enables partial turn-on and excessive quiescent current.
Use a star-ground topology with the BTS6163DAUMA1 GND pin tied directly to the battery-return star point; this keeps load current from modulating the logic ground that the IS pin measures. Keep the high-current OUT trace wide and short - 1 oz copper at 21.5 A continuous needs at least 5 mm trace width for <30 C rise. The exposed tab is electrically connected to OUT and must not be allowed to short to adjacent signals or to a non-isolated heatsink.
