BTS70101EPAXUMA1 - 9A Smart High-Side PROFET Switch | Infineon
MPN: BTS70101EPAXUMA1 ✓ Hoạt độngBTS70101EPAXUMA1 Tóm tắt
A high-side N-channel MOSFET switch (also called a smart high-side driver) is a power distribution topology where the load connects to ground and the switch sits between the positive rail and the load. Compared with low-side switching, high-side drivers offer inherent short-to-ground protection, controlled inrush-current behavior, and native compatibility with chassis-referenced vehicle loads. The PROFET+2 family targets intelligent power distribution in body and powertrain ECUs where ISO 7637-2 transient immunity and AEC-Q100 qualification are mandatory.
Key features include 9 A nominal load current, integrated reverse-battery protection (ReverSave), embedded thermal shutdown, over-current latch, open-load detection in both on and off states, and proportional load-current sensing via the IS pin. Operating supply voltage spans 6 V to 18 V with load-dump tolerance above 40 V, and the part is AEC-Q100 qualified for automotive use. The exposed thermal pad of the PG-TSDSO-14-22 package keeps junction-to-ambient thermal resistance low for continuous high-current loads such as seat heaters and HVAC blowers.
The BTS70101EPAXUMA1 integrates a vertical N-channel power MOSFET with a sophisticated analog/mixed-signal control and protection block, achieving diagnostic feedback comparable to discrete designs while maintaining the simplicity of a single-channel IC. Built-in protections reduce external BOM and PCB area versus discrete MOSFET-plus-fuse topologies.
Typical applications include automotive body controllers (BCM), HVAC blower and fan control, seat-heater and door-module drivers, LED driver front-ends, and industrial 24 V systems requiring protected switching. Engineers select the BTS70101EPAXUMA1 when they need a single channel of clean, diagnosed high-side switching rather than a quad-channel low-side array. Companion devices include the BTS7080-2EPA and BTS7120-2EPA within the PROFET+2 family.
Design consideration: dedicate a continuous copper pour under the exposed pad to module ground, keep the IS sense trace short and shielded, and use ReverSave to meet ISO 7637-2 reverse-polarity requirements without an external blocking diode.

Ứng dụng tiêu biểu
BTS70101EPAXUMA1 phù hợp cho 6 Áp dụngs: Automotive Body Control Module (BCM), HVAC Blower and Fan Control, Seat Heater Driver Front-End, Door Module Load Driver, Automotive LED Driver Front-End, Industrial 24 V Protected Load Switch.
Automotive Body Control Module (BCM)
The BTS70101EPAXUMA1's 9 A continuous rating, AEC-Q100 qualification, and integrated ReverSave reverse-battery protection make it ideal for automotive body controllers that drive mixed resistive and inductive loads such as door lock actuators, mirror heaters, and lighting channels. Placed between the 12 V battery rail and each load with a 1 kHz PWM control signal, the PROFET+2 part delivers proportional IS-pin current sensing back to the BCM MCU for closed-loop load monitoring. Compared to discrete N-channel MOSFET plus fuse solutions, the integrated diagnostics cut PCB area by roughly 60% while still meeting ISO 7637-2 jump-start and reverse-polarity requirements. Companion devices include the BTS7080-2EPA for adjacent lower-current channels.

HVAC Blower and Fan Control
HVAC blowers in 12 V automotive systems typically draw 6-8 A continuous with 2-3x inrush on motor startup, and the BTS70101EPAXUMA1's 9 A nominal rating with built-in over-current latch directly absorbs these transients without an external fuse. The exposed thermal pad of the PG-TSDSO-14-22 package sustains continuous 9 A operation when soldered to a 1 square-inch copper pour, while the IS pin delivers real-time load-current feedback for stall detection. According to the Infineon datasheet, the proportional current sense eliminates the need for a separate shunt resistor and simplifies blower-speed closed-loop control. The part is a drop-in alternative to legacy BTS series with the same TSSOP-14 EP footprint.

Seat Heater Driver Front-End
Seat-heater loads in automotive cabins draw 5-8 A per seat at 12 V with strong temperature-dependent resistance variation, and the BTS70101EPAXUMA1's 9 A rating gives comfortable headroom for cold-cable inrush. The PROFET+2 device provides IS-pin proportional current sense so the body controller can implement PWM-based heating profiles and detect open-heater-mat faults. AEC-Q100 qualification across -40 C to +150 C junction temperature ensures reliable operation in cabin environments. Using the BTS70101EPAXUMA1 instead of a discrete MOSFET eliminates the external reverse-battery blocking diode and saves roughly 40% PCB area in the seat-module housing.

Door Module Load Driver
Automotive door modules aggregate multiple loads (window lift, mirror fold, puddle lamp, lock actuator) and the BTS70101EPAXUMA1 serves as a robust single-channel high-side driver for the highest-current channel such as a window-lift motor. The integrated ReverSave reverse-battery protection and over-current latch handle motor-stall events without external fuses, while IS-pin sensing enables stall and jam diagnostics. Its PG-TSDSO-14-22 package allows PCB reuse across door-module variants - lower-power channels can substitute the BTS7080-2EPA without layout changes. AEC-Q100 grade and >40 V load-dump tolerance meet the harshest automotive transient requirements per ISO 7637-2.

Automotive LED Driver Front-End
High-brightness automotive LED headlamp or DRL strings typically draw 3-7 A at 12 V, and the BTS70101EPAXUMA1 acts as a robust high-side switch ahead of a downstream buck or linear LED driver. The PROFET+2 part provides IS-pin proportional current sense for thermal fold-back and LED-string fault detection, while AEC-Q100 qualification and ReverSave reverse-battery protection ensure reliable operation in the engine-bay environment. The PG-TSDSO-14-22 footprint enables compact PCB layouts behind headlamp assemblies where space is at a premium. Designers select this part when they want one IC to handle the high-side disconnect and another to perform the constant-current LED regulation.

Industrial 24 V Protected Load Switch
Beyond automotive, the BTS70101EPAXUMA1's 6 V to 18 V operating range and reverse-battery protection make it usable in industrial 24 V systems (with a pre-regulator) for solenoid, relay coil, and small-motor switching. The integrated over-current latch protects wiring harnesses from short-circuit events, while IS-pin current sensing supports predictive-maintenance algorithms in PLC and IIoT nodes. The PG-TSDSO-14-22 surface-mount package suits modern reflow-assembled industrial controllers, replacing legacy TO-220 mechanical relays with a solid-state alternative that adds no audible click and survives millions of cycles. Per the Infineon datasheet, the part exceeds 40 V load-dump tolerance for harsh electrical environments.

Ghi chú thiết kế
Estimated: at 9 A continuous load with VIN=12 V, VOUT=0.3 V (RDS(on) approximated from PROFET+2 family data), conduction loss is approximately 2.7 W. The PG-TSDSO-14-22 package requires a copper pour of at least 1 square inch connected to the exposed pad to keep junction temperature rise below 50 C above ambient. Without adequate copper, the device may enter thermal shutdown under sustained 9 A load. Use thermal vias under the EP for multi-layer boards to spread heat into inner planes.
Solder the exposed pad (EP) to a continuous copper pour tied to module ground; this is the primary thermal dissipation path. Place a 100 nF ceramic decoupling capacitor as close as possible to the VS pin and the GND pin to suppress high-frequency noise on the supply rail. Keep the IS sense trace short and away from switching nodes to avoid capacitive coupling that would corrupt current-sense accuracy. According to the Infineon application note, a 4-layer PCB with a dedicated ground plane is strongly recommended for automotive designs.
Do not float the IN pin; tie IN either high or low through the MCU to avoid undefined IN-state leakage that may partially turn on the output stage. The fault flag from the diagnostic pin can latch after an over-current event - the MCU must clear the latch by cycling IN according to the Infineon datasheet timing diagram. ReverSave reverse-battery protection handles reverse polarity, but the device still requires a properly rated external supply fuse to protect against sustained over-voltage events beyond 40 V load-dump.
PWM dimming of LED or heater loads up to 1 kHz is well within the BTS70101EPAXUMA1's switching capability, but above 5 kHz the IS-pin current sense begins to attenuate due to internal filtering - use a slower PWM for accurate current monitoring. When driving inductive loads (solenoids, relays, small motors), add a TVS diode or snubber to clamp the demagnetization voltage below the 40 V absolute maximum. Per Infineon design guidance, place the snubber close to the load terminals to minimize loop inductance.
