BTS3011TEATMA1 概要
A Smart Low-Side Power Switch is a semiconductor that controls a load by switching the ground return path rather than the supply rail, providing a cost-effective way to drive resistive or inductive loads such as solenoids, valves, lamps, relays, and LED strings. The category sits within Power Distribution Switches > Load Drivers in the broader PMIC taxonomy, and combines a power MOSFET with protection and diagnostic logic into a single IC - eliminating the need for discrete protection circuitry around a bare MOSFET. Low-side switches are favored when the load is referenced to a common chassis ground and when fast demagnetization of inductive loads is required through active freewheeling.
Differentiating features include 11 mΩ typical on-resistance at 25 °C, ±8 kV HBM ESD robustness on the output pin, an operating junction temperature range of -40 °C to +150 °C, and a logic-level CMOS-compatible input. The integrated inverse-current protection and ground-loss protection improve fault tolerance on automotive wiring harnesses where shorts to ground or battery are common. The 5-pin DPAK footprint provides a tab for low thermal resistance, enabling continuous 10 A operation without external heatsinking on typical 1 oz copper PCB areas.
The device is built on Infineon's proprietary N-channel vertical power MOSFET process, optimized for low on-resistance per unit area in the 30 V class. Internal charge pump and gate driver circuitry ensure full enhancement of the power stage even at low battery voltages down to 3 V during cranking transients. A status flag pin provides open-drain feedback for fault detection by an external microcontroller.
Typical applications include automotive body electronics (door lock actuators, mirror heaters), 12 V LED lighting modules, relay and solenoid replacement in HVAC and powertrain ECUs, and industrial 24 V load switching. The AEC-Q100 Grade 1 qualification makes it suitable for under-hood and chassis-mounted modules exposed to wide temperature swings.
When designing with this device, ensure that the load's inrush current does not exceed the inrush current limit, and that adequate copper area is provided on the drain tab for thermal dissipation. The input pin must be driven from a microcontroller GPIO capable of sourcing the pull-up current; a series resistor may be required to limit inrush into the logic input.

12 V Automotive LED Lighting Modules
The BTS3011TEATMA1 serves as the low-side switch for 12 V LED daytime running lights, tail lamps, and interior lighting modules. With 11 mΩ R_DS(on), it dissipates only about 110 mW at 1 A LED string current, eliminating the need for thermal management. The Infineon datasheet specifies ±8 kV HBM ESD protection on the output pin - critical for outdoor lamp modules exposed to handling and environmental ESD events. The 3-28 V operating range tolerates load-dump transients up to 28 V and cold-crank drops to 3 V without dropout. PWM dimming is supported by toggling the logic input up to 1 kHz with smooth current transitions.
おすすめ
Relay and Solenoid Replacement in HVAC ECUs
The BTS3011TEATMA1 replaces electromechanical relays for HVAC damper solenoids and blend door actuators, delivering silent operation and longer service life. The 10 A continuous rating covers even large blend door motors that draw 5-7 A inrush. Integrated inverse-current protection - per the Infineon HITFET +12V datasheet - protects the IC from back-EMF when switching inductive loads. The status flag pin enables the ECU to detect open-circuit faults (broken solenoid) and short-circuit faults (stuck actuator) without external sense resistors, reducing BOM and PCB area. AEC-Q100 Grade 1 qualification ensures operation up to +150 °C junction under dashboard mounting.
おすすめ
Industrial 24 V Load Switching
The BTS3011TEATMA1 operates from 3 V to 28 V making it suitable for industrial 24 V bus systems controlling small solenoids, indicators, and relay coils. The 10 A continuous current supports most PLC-output-style loads directly. According to the Infineon datasheet, integrated over-temperature shutdown and over-voltage clamp provide robust protection in electrically noisy factory environments where 24 V rails experience inductive spikes. The DPAK-5 surface-mount package supports automated assembly and reflow soldering compatible with standard industrial PCB processes. Logic-level CMOS input interfaces directly with 3.3 V or 5 V PLC outputs without level shifters.
おすすめ
Mirror Heater and Seat Heater Switching
The BTS3011TEATMA1 drives resistive heating elements in automotive mirror and seat heaters at currents up to 10 A. Its 11 mΩ R_DS(on) keeps conduction loss below 1 W at full load - per the Infineon datasheet - simplifying thermal design in space-constrained door modules and seat frames. PWM control through the logic input enables variable heating levels for temperature regulation. The integrated current limit protects against short-to-ground faults in the heating element wiring, while the status feedback pin alerts the body controller to fault conditions for diagnostic logging required by OBD-II in some markets. AEC-Q100 Grade 1 qualification supports underbody mounting.
おすすめ
Fuel Pump and Water Pump Relay Driver
The BTS3011TEATMA1 drives 12 V automotive fuel pump and water pump relays, replacing electromechanical relays with solid-state reliability. With 10 A continuous current handling, it covers the relay coil current with substantial margin. Per the Infineon HITFET datasheet, the device's ground-loss protection prevents damage when the control module loses chassis ground - a known failure mode in automotive wiring. The status flag confirms proper relay operation back to the ECU, enabling fault detection without additional sense circuitry. AEC-Q100 Grade 1 and -40 °C to +150 °C junction rating support engine bay mounting.

設計ノート
Estimated: at 10 A continuous current and 11 mΩ R_DS(on), conduction loss is approximately P = I² × R = 100 × 0.011 = 1.1 W. With DPAK-5 R_thJA of approximately 50 K/W on minimum copper (JEDEC 1s0p), junction temperature rise above ambient is about 55 °C. For continuous 10 A operation in 85 °C ambient (under-hood), the junction reaches approximately 140 °C - below the 150 °C limit. To maintain margin, provide at least 1 sq inch of 2 oz copper on the drain tab, reducing R_thJA to ~25 K/W and junction rise to ~28 °C. For continuous operation above 8 A, add thermal vias to inner PCB planes.
Per Infineon application guidelines, place the BTS3011TEATMA1 with the drain tab directly over a copper pour connected to the load return path. Use thermal vias (typically 9-16 vias of 0.3 mm diameter) under the tab to inner ground or power planes for improved heat spreading. Keep the input trace short to minimize noise coupling into the CMOS gate. Add a 100 nF ceramic bypass capacitor close to the IN pin if the input trace exceeds 10 mm. The OUT pin connects to the load; ensure the PCB trace width supports 10 A continuous (typically 2-3 mm wide on 1 oz copper).
Do not operate the BTS3011TEATMA1 above 28 V; load-dump transients in 12 V automotive systems can exceed this. Add an external TVS diode (e.g., 30 V SMA) at the load supply for protection against jump-start events. Per the Infineon datasheet, do not leave the input pin floating - always drive it from a defined logic source, otherwise the internal MOSFET may partially enhance and dissipate excess power. The status pin is open-drain and requires an external pull-up resistor (typically 10 kΩ to V_DD); do not connect it directly to a voltage source.
Per Infineon HITFET +12V application note, route the high-current load path (load supply → load → OUT pin → TAB → back to supply ground) with wide, short traces to minimize parasitic inductance. The GND pin must connect directly to the system ground plane with a via close to the pin - a long GND trace creates a ground bounce that can confuse the status comparator. Keep the input logic trace away from the OUT trace to prevent capacitive coupling that could falsely trigger the device. If the load is inductive (solenoid, relay, motor), add a flyback diode or use the device's built-in inverse current handling to clamp back-EMF.
