BTS70202EPAXUMA1 개요
A high-side power switch is a semiconductor device that sits between the supply rail and the load, replacing a relay or discrete MOSFET+driver pair. It controls power to resistive or inductive loads such as lamps, solenoids, motors, and LED strings, while also providing protection and diagnostic feedback. Within the broader power-management hierarchy, high-side switches sit alongside low-dropout regulators (LDOs) and DC-DC converters as system-level power-conditioning blocks; within Infineon's PROFET+ family, they are the most integrated option, embedding protection, driving, and sensing into a single die.
The BTS70202EPAXUMA1 integrates per-channel protection: load-current limitation, short-circuit shutdown, over-temperature latch-off, over-voltage clamp (including inductive load demagnetization), reverse-battery protection through an external ground-referenced resistor network, and loss-of-ground/battery detection. Each channel also provides an analog current-sense (IS) pin that scales with load current for ADC-based diagnostics, plus a dedicated enable input for PWM and multiplexing flexibility.
A key feature is the configurable current-limit setpoint (default ~12 A ICL0, with selectable ICL1 thresholds via the SEL pin) and a typical on-state resistance of about 30 mΩ per channel, which keeps conduction losses low at full load. The device supports 3.3 V and 5 V microcontroller logic on its input pins and meets the strict electromagnetic-compatibility requirements of automotive body and chassis ECUs.
Typical applications include automotive body control modules for driving LED tail-lights, interior lighting, and seat heaters; industrial PLC digital outputs; 24 V industrial sensor and actuator power; and any 12 V/24 V distributed power system needing per-channel fault reporting back to a host MCU. Designers pair the BTS70202EPAXUMA1 with a small automotive MCU such as Infineon's TLE984x or TC2x family for protected, diagnosable load driving.
When designing with this part, place a low-ESR 100 nF ceramic bypass capacitor directly on Vbb, follow the PCB layout recommendations in the PROFET application notes for thermal copper spreading under the exposed pad, and confirm that the configured ICL threshold leaves margin above the maximum inrush current of the specific load (e.g., cold filament lamp or motor stall). The sense resistor must be Kelvin-connected to GND to preserve current-mirror accuracy.

일반적인 애플리케이션
BTS70202EPAXUMA1 적합 용도: 6 애플리케이션s: Automotive Body Control Module (BCM), Automotive LED Tail-Light and Daytime Running Light Driver, Industrial 24 V PLC Digital Output Module, Solenoid and Relay Replacement in HVAC Actuators, 24 V Industrial Sensor and Actuator Power Distribution, Automotive Seat Heater and Seat Adjustment Driver.
Automotive Body Control Module (BCM)
The BTS70202EPAXUMA1 is a natural fit for automotive body control modules that drive exterior lighting, mirror heaters, and seat adjustment motors. Its 6-18 V Vbb range tolerates direct 12 V battery connection, while the 30 mΩ per-channel Rds(on) keeps conduction losses below 0.4 W at 2.5 A continuous load - manageable without an external heatsink. The analog current-sense (IS) pin enables the host MCU to detect open-load, short-to-ground, and over-current faults in real time, which is critical for ASIL-rated BCM firmware. The exposed-pad PG-TSDSO-14-22 package spreads heat into the inner PCB copper layers, supporting the -40 C to +125 C automotive ambient range under the dashboard. Compared to electromechanical relays, this part eliminates click noise, bounce, and mechanical wear.

Automotive LED Tail-Light and Daytime Running Light Driver
The BTS70202EPAXUMA1 drives LED tail-light and DRL strings with PWM dimming up to several hundred hertz. Each channel's 12 A current limit and over-temperature latch-off protect against LED short-circuit failure modes, while the analog sense pin provides a multiplexed ADC feedback channel for thermal fold-back and open-string detection. The 2.5 A per-channel continuous rating comfortably drives LED strings up to 25 W per side at 12 V. Designers typically place 100 nF ceramic bypass caps on Vbb within 5 mm of the IC pins to suppress PWM edge transients and meet CISPR 25 Class 5 EMI limits. The PROFET family's proven automotive EMC pedigree reduces qualification time versus discrete MOSFET designs.

Industrial 24 V PLC Digital Output Module
For industrial PLC digital output modules sinking or sourcing 24 V loads, the BTS70202EPAXUMA1 provides two protected outputs in a single chip, reducing module size and BOM cost. The 6-18 V nominal Vbb range covers most 12 V and 24 V PLC rails when paired with an upstream pre-regulator, while the device's diagnostic outputs feed directly into the PLC's safety MCU for IEC 61131-2 fault reporting. The reverse-battery and loss-of-ground protection features, combined with integrated over-temperature shutdown, simplify the IEC 61131-2 certification path for industrial control cabinets. The exposed-pad package enables sustained operation at 2.5 A per channel in sealed enclosures with limited airflow.
추천
Solenoid and Relay Replacement in HVAC Actuators
The BTS70202EPAXUMA1 is well-suited to driving small DC solenoids and HVAC damper actuators, where silent operation and long-term reliability outweigh the small BOM cost premium over discrete transistors. Each channel's inductive-load demagnetization clamp handles the flyback energy from a de-energized solenoid without external freewheeling diodes, and the 30 mΩ Rds(on) keeps thermal dissipation under 0.2 W per channel at 2 A continuous. The dual-channel architecture enables two-zone HVAC control from one IC. Designers must ensure the configured ICL threshold sits above the solenoid inrush current (often 3-5x the steady-state value) to avoid nuisance tripping during actuator engagement.

24 V Industrial Sensor and Actuator Power Distribution
In distributed 24 V industrial systems - such as machine vision lighting, conveyor sensors, and valve manifolds - the BTS70202EPAXUMA1 provides per-channel protection and remote diagnostics over a single wire pair. The analog IS pin can drive a 4-20 mA-style current loop back to the controller, enabling predictive maintenance by detecting gradual load drift. Each channel's 2.5 A continuous rating covers most sensor-cluster loads, and the parallel-output mode (both channels ganged together) supports 5 A for higher-power lighting bars. The wide operating temperature range and Infineon's automotive-grade reliability pedigree translate directly to factory-floor uptime requirements.
추천
Automotive Seat Heater and Seat Adjustment Driver
The BTS70202EPAXUMA1 drives resistive seat heater pads and bidirectional seat adjustment motors from a single Infineon PROFET+ chip. Its dual channels can be PWM-modulated at audio frequencies above 20 kHz to drive seat heater MOSFETs in parallel for higher current, or used independently to control two seat zones. The integrated current-sense output enables the body controller to detect heater-element failure (open-circuit) and over-current conditions that indicate a pinched wire, both of which are required for FMVSS 302 compliance testing. The exposed-pad package keeps junction temperature below 150 C even when mounted under the seat with minimal airflow, and the -40 C cold-start rating handles arctic-climate operation.

설계 노트
Estimated: at 2.5 A per channel continuous load and 30 mΩ Rds(on), each channel dissipates approximately P = I² × Rds(on) = 2.5² × 0.030 = 0.19 W. With both channels at full load, total dissipation reaches 0.38 W. The PG-TSDSO-14-22 package has a junction-to-ambient thermal resistance of roughly 40 C/W on a standard 4-layer JEDEC EIA/JESD51 test board, giving a 15 C temperature rise above ambient - well within the 150 C junction limit. For sealed enclosures with poor airflow, increase the PCB copper pour area beneath the exposed pad and add thermal vias to the inner layers to drop the effective θJA below 30 C/W.
Place a 100 nF X7R ceramic bypass capacitor within 5 mm of the Vbb pin to suppress voltage transients caused by load inductance and PWM switching. The exposed thermal pad must be soldered to a PCB copper pour of at least 1 square cm on the top layer, with a 5x5 array of 0.3 mm thermal vias connecting to inner ground planes. Keep high-current OUT traces wide (≥ 1 mm per ampere) and short to minimize voltage drop and parasitic inductance. Per the Infineon PROFET application note, the sense-resistor ground return must be a Kelvin connection to the IC's GND pin to preserve current-mirror accuracy - do not share the sense ground with high-current power ground.
Do not exceed the configured current-limit threshold during normal load inrush - this is the most common cause of PROFET latch-off in the field. Cold filament lamps can draw 10x their steady-state current at turn-on, and DC motor stall currents reach 5-7x running current. Always measure the inrush with an oscilloscope and current probe on a prototype, and select the ICL0 or ICL1 setting (via the SEL pin) to leave at least 50% margin above the measured inrush peak. Also, never leave the IN pin floating - tie it to GND with a 10 kΩ pulldown if the MCU GPIO is high-impedance during boot, otherwise an undefined input can partially turn on the output stage and cause excessive quiescent current.
The BTS70202EPAXUMA1's PWM rise time is internally limited to roughly 1-2 µs to meet automotive CISPR 25 EMI limits. For applications requiring even softer edges (e.g., to meet Class 5 conducted emissions), add a small series gate resistor (10-47 Ω) between the MCU GPIO and the IN pin, combined with a 1 nF RC snubber on the OUT pin if load inductance is significant. The analog IS pin output is a current-source signal that is naturally immune to common-mode noise, but route the IS trace away from switching power lines and keep it short to avoid injecting PWM switching noise into the host MCU's ADC measurement.
