BTG70013A1ESWXUMA2 Overview
A high-side switch is a power-distribution building block that sits between the supply rail (typically the automotive 12 V battery) and the load, replacing discrete fuses, relays, and MOSFET drivers. It belongs to the broader category of smart power switches (also called intelligent power switches, IPS, or PROFET devices), which integrate a power transistor, gate driver, current sense, and diagnostic feedback into one IC. Within a vehicle electrical/electronic (E/E) architecture, it sits under the body control module (BCM) and power distribution box, protecting wiring harnesses from over-current and short-circuit events while reporting fault status back to the MCU.
Key specifications of the BTG70013A1ESWXUMA2 include a 26.6 A maximum load current, an active-high logic input, a selectable integrated I²t wire-harness protection function, an IDL pin for microcontroller wake-up from key-off mode, and an operating supply current under 60 µA in active key-off (idle) mode. Embedded protection features include over-current, over-voltage, over-temperature, reverse battery, and loss-of-ground protection per Infineon's PROFET datasheet. The device is rated for use with 12 V automotive loads and supports diagnostic feedback through a status / current-sense pin.
The BTG70013A uses a vertical DMOS output stage driven by a charge-pump-assisted gate driver, enabling true rail-to-rail low-RDS(on) switching in a small PG-TSDSO-24-32 thermal-enhanced package. The integrated I²t characteristic lets designers select a wire-protection curve by external component choice, matching the thermal limit of the harness rather than a fixed silicon trip point. This is critical for AEC-Q100 and ISO 26262-compliant automotive wiring systems where the wire itself is the weakest thermal element.
Typical applications include automotive body-electronic loads such as LED lighting modules, seat heaters, mirror heaters, auxiliary 12 V outlets, and small DC motor drivers. It is also used in industrial 24 V systems and truck / agricultural 24 V body controllers where 12 V-class smart switches are deployed per channel. The low idle current under 60 µA makes it suitable for permanently-live nodes that must not drain the battery during key-off parking.
When designing with this part, ensure the PCB layout provides sufficient copper area on the exposed pad for thermal dissipation, place the input/bulk capacitor as close as possible to the VBB pin, and configure the I²t selection network per the application curve in the datasheet. The IDL wake pin must be wired to an MCU interrupt-capable GPIO to use the key-off wake feature; floating this pin disables the wake function but does not affect normal operation.

Automotive LED Lighting Modules
The BTG70013A1ESWXUMA2's 26.6 A load capability and 12 V supply operation make it well suited to drive automotive exterior and interior LED lighting loads such as daytime running lights, tail lamps, and headlamp modules. The integrated I²t wire-harness protection matches the trip curve to the cable's thermal limit, protecting thin-gauge wiring from chronic over-current without nuisance trips. The <60 µA idle current supports always-on lighting nodes that must not drain the battery during key-off parking, while the IDL pin wakes the BCM when the driver operates the lighting switch.

Automotive Seat Heater Driver
The BTG70013A1ESWXUMA2 is commonly deployed as a high-side seat-heater switch in body control modules. Its 26.6 A current rating covers high-power seat heaters with carbon-foil or wire-wound elements drawing 10-15 A continuous, with margin for inrush. Embedded over-temperature and over-current protection prevent fire risk if a heater element shorts, while I²t protection preserves the harness against pin-chafing damage. ISO 26262 compliance supports use in safety-related seating systems where functional-safety documentation is required.
Recommended
Auxiliary 12 V Power Outlet / Cigarette Lighter Receptacle
Auxiliary 12 V outlets in passenger compartments and cargo areas benefit from the BTG70013A1ESWXUMA2's 26.6 A continuous rating and I²t wire protection. The device safely interrupts over-current events such as a foreign object wedged in the socket or a shorted accessory plug, without requiring a service-replaceable fuse. Diagnostic feedback via the IS / STATUS pin alerts the BCM to log the fault, and the ISO 26262 documentation supports ASIL-rated power-distribution architectures used by OEMs.
Recommended
Mirror Heater and Washer Heater Control
Mirror heaters in cold-climate automotive markets draw 2-5 A continuous, well within the BTG70013A1ESWXUMA2's 26.6 A envelope, while its low RDS(on) minimizes conduction losses across long mirror-harness runs. The exposed pad on PG-TSDSO-24-32 enables compact PCB placement near the mirror connector, and the IDL pin supports wake-on-touch features in premium vehicles. Reverse-battery and loss-of-ground protection guard against wiring faults during service or accident events.
Recommended
Industrial 24 V DC Solenoid and Valve Driver
Beyond automotive, the BTG70013A1ESWXUMA2 is used in industrial 24 V PLC and process-control systems to switch solenoid valves, hydraulic actuators, and pneumatic valves. The PROFET's <60 µA idle current suits battery-backed industrial controllers, and the embedded protection functions handle the inductive kickback and over-temperature conditions common in solenoid switching. The exposed pad provides adequate thermal dissipation for continuous-duty industrial cycles.
Recommended
Truck / Commercial Vehicle 24 V Body Controller
In heavy-duty trucks and commercial vehicles, the BTG70013A1ESWXUMA2 is used to switch marker lights, cab heaters, and 12 V-derived body loads from a 24 V battery when paired with a pre-regulator. The 26.6 A rating and AEC-Q100 / ISO 26262 compliance suit harsh under-hood environments with high vibration and temperature swings. Diagnostic feedback enables fleet telematics to log switch events and fault counts for predictive maintenance.
Recommended
Small DC Motor Driver (Pump / Fan)
Small DC pumps and cooling fans in automotive thermal-management systems draw 5-15 A continuous with higher inrush at startup; the BTG70013A1ESWXUMA2 handles both regimes within its 26.6 A envelope. The integrated I²t characteristic can be tuned to allow motor-start inrush while still protecting the harness against locked-rotor conditions. The exposed pad and PG-TSDSO-24-32 footprint enable compact under-hood placement close to the pump or radiator fan.

Design Notes
Estimated: at VBB=14 V, VOUT≈0.1 V (saturated), and continuous 26.6 A load, the BTG70013A1ESWXUMA2 dissipates roughly P = I² × RDS(on). For a 10 mΩ RDS(on), this is ~7 W. The PG-TSDSO-24-32 package requires a substantial copper pour on the exposed pad (≥6 cm² on outer layers) to keep theta_JA below 30 C/W. Without adequate copper, the device will derate or trip thermal shutdown well before reaching rated current.
Place the VBB bulk capacitor (≥10 µF X7R plus a 100 nF ceramic) within 5 mm of the VBB pin to suppress load-dump and ISO 7637-2 transient pulses that are common in 12 V automotive environments. The exposed pad must be soldered to a continuous thermal land with thermal vias to inner copper planes. The IS / STATUS pin trace should be kept short and routed away from the OUT switching node to avoid coupling noise into the diagnostic feedback path.
Do not float the IDL pin if wake-on-event functionality is required; floating it disables the wake function but does not affect normal ON/OFF switching. The I²t selection network (typically an R-C on a dedicated pin) must be sized per the harness gauge in the datasheet application curve - choosing a too-aggressive curve causes nuisance trips on cold starts, while a too-relaxed curve defeats wire protection. Always observe the reverse-battery maximum rating during service conditions.
Route the high-current OUT trace on an outer layer with wide copper (≥2 mm per ampere for sustained 26.6 A operation) and stitch the return path on the opposite inner layer. The exposed thermal pad should be a single contiguous land rather than a split pattern, with an array of 0.3 mm thermal vias on a 1.0-1.2 mm grid. Avoid routing sensitive analog signals (sensor feedback, IS pin) under the OUT trace to minimize capacitive coupling during switching transients.
The BTG70013A1ESWXUMA2 switches at sub-µs edge rates that can inject common-mode noise into nearby analog circuits. Place a small ferrite bead or RC snubber on the OUT pin if the load is a long cable harness (>0.5 m), and keep the diagnostic IS / STATUS trace short and guarded by ground. The IDL wake signal should be routed with ground reference to avoid false wake events from injected noise during load switching.
