Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this component. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
BTS700201ESPXUMA2 is suitable for 6 applications: Automotive Front and Rear Lighting, Body Control Module (BCM) Loads, HVAC Blower and Fan Motors, Industrial 24 V Solenoid and Relay Replacement, Power Distribution and Fuse Replacement, Auxiliary Heater and PTC Heating.
Automotive Front and Rear Lighting
The BTS700201ESPXUMA2 drives LED headlamp modules, tail lamps, and turn signals from a 12 V battery rail with 23.2 A continuous capability. Its 2.3 mOhm typical RDS(ON) minimizes conduction loss so multi-LED strings reach full brightness without thermal stress on the switch. The IS pin provides diagnostic current-sense feedback to the BCM for open-load and short-circuit detection, while integrated reverse-battery and load-dump protection (70 V transient) withstands harsh automotive electrical transients. This makes it well suited to replace electromechanical lighting relays.
Recommended
Body Control Module (BCM) Loads
Within a body control module, the BTS700201ESPXUMA2 powers seat heaters, window lifts, door locks, and mirror adjusters directly from the 12 V bus. Its 23.2 A rating handles inrush from DC motors while the embedded current limit and over-temperature shutdown protect against stall conditions. Per Infineon application notes, the device operates across -40C to +150C, matching under-hood and cabin ambient profiles. The 1:1 input-to-output digital control interface allows direct GPIO drive from the BCM microcontroller.
Recommended
HVAC Blower and Fan Motors
The BTS700201ESPXUMA2 is well matched to 12 V HVAC blower motors and cooling fans where steady-state current can approach 20 A. Its low 2.3 mOhm RDS(ON) reduces heat dissipation at full load, while the exposed-pad PG-TSDSO-24-32 package spreads heat into PCB copper. Integrated PWM capability (driven from the IN pin) allows variable fan-speed control without external MOSFETs. The IS pin current sense provides stall and blockage detection for safety diagnostics.
Recommended
Industrial 24 V Solenoid and Relay Replacement
In industrial automation, the BTS700201ESPXUMA2 replaces electromechanical relays driving 24 V solenoids, valves, and indicator loads. The 70 V transient rating tolerates inductive kick from de-energized coils, and the diagnostic IS pin reports wiring faults to a PLC. AEC-Q100 qualification extends lifetime in factory environments with thermal cycling. Its solid-state design eliminates contact bounce and arcing, improving reliability over mechanical switching.
Recommended
Power Distribution and Fuse Replacement
The BTS700201ESPXUMA2 acts as a resettable electronic fuse in 12 V distribution boxes, replacing blade fuses with software-controlled switching. Per Infineon datasheet, the integrated current limit and over-temperature shutdown self-protect downstream wiring during overload conditions, eliminating the need to replace blown fuses. The IS pin allows fault logging in the body control module for predictive maintenance. Multiple BTS700201ESPXUMA2 channels can be paralleled in software for higher-current rails.
Recommended
Auxiliary Heater and PTC Heating
PTC cabin heaters and auxiliary heating elements draw sustained high current from 12 V rails, making the BTS700201ESPXUMA2 a suitable solid-state driver. With 23.2 A continuous rating and 2.3 mOhm RDS(ON), it minimizes dissipation in confined under-dash installations. The exposed thermal pad of the PG-TSDSO-24-32 package supports PCB copper heat spreading. The device's diagnostic IS pin enables overtemperature and fault reporting to the climate control module.

Key Differentiators
- 23.2 A continuous current in a single PG-TSDSO-24-32 channel (vs BTS428L2ATMA1)
- Single-channel high current vs dual-channel lower current (vs BTS700202EPAXUMA1)
- Lower RDS(ON) than other family members (vs BTS700102EPAXUMA1)
Design Notes
Estimated: at 23.2 A load current with 2.3 mOhm typical RDS(ON), the conduction loss is approximately 1.23 W. Combined with switching losses in PWM applications, the PG-TSDSO-24-32 exposed pad should be soldered to at least 6 square centimeters of copper to keep the junction-to-ambient thermal resistance within acceptable limits. For continuous high-current operation above 15 A, additional copper on inner PCB layers connected via thermal vias is recommended.
Do not connect the IS pin directly to 5 V or 3.3 V logic - it is a current source output requiring a pull-down resistor to ground (typically 1 kOhm). The IS pin voltage must be limited to the ADC reference of the monitoring microcontroller to avoid damage. Per Infineon datasheet, IS pin leakage in OFF state can cause false open-load detection if the wiring harness has significant capacitance; add a small RC filter if fault flags are spurious.
Keep high-current traces (VBB and OUT) wide and short to minimize parasitic inductance that can produce voltage transients during turn-off. Place a 100 nF ceramic decoupling capacitor close to the VBB pin to absorb fast transients. The exposed pad (EP) must be soldered for both thermal performance and mechanical reliability; thermal vias to internal copper planes significantly improve heat spreading.
Although the BTS700201ESPXUMA2 integrates reverse-battery protection, an external TVS diode (such as SMBJ series) on the VBB line is recommended for severe load-dump transients beyond ISO 7637-2 pulse B requirements. The internal protection handles 70 V transients, but sustained overvoltage conditions may still activate the over-temperature shutdown. Verify TVS clamping voltage is below the 70 V maximum load voltage rating.
