BTS71202EPGXUMA1 개요
A high-side switch is a power-MOSFET driver topology where the load is tied to ground and the switch sits between the positive supply rail and the load. Compared with low-side switches, high-side drivers simplify wiring harnesses, eliminate ground-shift issues, and integrate easily into automotive body-control modules where chassis ground returns are long and noisy. The BTS71202 sits inside the broader PROFET family of protected switches (which are part of Infineon's power-management IC portfolio) and is a member of the 12 V automotive smart-switch category.
Key features of the BTS71202 include 110 mΩ typical on-resistance per channel at room temperature, very low standby current (~0.5 µA typ), integrated clamping for inductive loads, AEC-Q100 qualification, and a SPI-compatible diagnostic feedback path via the IS pin. Its PROFET +12V heritage means the device meets the stringent ISO 7637 transient, jump-start (36 V), and reverse-battery (–16 V) requirements common on vehicle 12 V buses.
Architecturally, each channel stacks an N-channel power MOSFET with a charge pump and gate driver, plus analog current-sense and digital protection logic. The current-sense output delivers a current proportional to the load current, allowing the host MCU to detect open-load, short-to-ground, and over-current conditions without a discrete shunt resistor.
Typical applications include automotive body-control modules, LED driver modules, relay and solenoid replacement, distributed power-distribution nodes, and general-purpose 12 V high-side switching in industrial systems. Compared with electromechanical relays, the BTS71202 offers smaller PCB area, no contact bounce, silent operation, and embedded diagnostics, while maintaining comparable current-handling capability.
When designing with the BTS71202, place the device close to the load connector to minimize inductance in the high-current path, and reserve copper area for thermal dissipation since two channels can deliver a combined 4 A continuous in still air. A 100 nF X7R decoupling capacitor must be placed within a few millimetres of the Vbb pin to handle ISO 7637 transient pulses.

일반적인 애플리케이션
BTS71202EPGXUMA1 적합 용도: 6 애플리케이션s: Automotive Body Control Module (BCM), Automotive LED Tail Lamp Driver, Relay & Solenoid Replacement, Industrial 12 V / 24 V Distribution Nodes, Heated Seat Control Module, 12 V Battery Management Disconnect.
Automotive Body Control Module (BCM)
The BTS71202EPGXUMA1 is a natural fit for automotive body-control modules driving exterior lighting, door locks, mirror heaters, and small solenoids. With two independent 2 A channels per IC, one device handles two loads, reducing BOM count and PCB area. The IS-pin current sense lets the BCM distinguish a burned-out bulb from a wiring fault, supporting OBD-II diagnostic requirements. The AEC-Q100 qualification and ISO 7637 transient tolerance meet 12 V vehicle electrical-environment standards without external TVS protection.
추천
Automotive LED Tail Lamp Driver
Driving LED tail-lamp assemblies requires accurate fault detection and PWM dimming for stop/tail/turn functions. The BTS71202EPGXUMA1's 110 mΩ Rds(on) keeps conduction loss low even at full brake-lamp current, and its analog IS output reports open-load when an LED fails. The active-high CMOS input accepts direct PWM from an MCU at up to 200 Hz with clean edges, avoiding the audible flicker that plagues relay-driven designs. AEC-Q100 + 28 V load-dump survival make it robust against automotive electrical hazards.
추천
Relay & Solenoid Replacement
Replacing electromechanical relays with the BTS71202EPGXUMA1 yields silent operation, no contact bounce, longer life, and embedded diagnostics. Each channel directly drives solenoid coils and DC motors up to 2 A continuous, with built-in inductive clamping that absorbs the flyback energy when the field collapses — eliminating the need for flyback diodes on the load. The PROFET +12V family also survives reverse-battery polarity, a frequent failure mode when jump-starting vehicles incorrectly.
추천
Industrial 12 V / 24 V Distribution Nodes
Beyond automotive, the BTS71202EPGXUMA1 serves in industrial 24 V DC distributed systems where each node controls a solenoid valve, indicator, or actuator. The 28 V absolute-max supply comfortably covers 24 V nominal rails with margin for transients, and the dual channels enable two loads per IC — useful in PLCs and remote I/O blocks. Current sense over the IS pin lets a controller identify failing actuators before they cause machine downtime, supporting predictive-maintenance strategies.
추천
Heated Seat Control Module
Heated-seat modules in vehicles use PWM control of resistive heating elements, with current sensing for fault detection. The BTS71202EPGXUMA1's two channels can drive the seat-cushion and seat-back heaters independently, allowing zone-by-zone temperature control. The IS-pin output enables detection of heater-element failures (open-circuit) and over-current conditions (shorted element) without a dedicated shunt resistor. AEC-Q100 qualification and –40 °C to +150 °C thermal range suit under-seat environments.
추천
12 V Battery Management Disconnect
The BTS71202EPGXUMA1 can serve as a low-current disconnect switch in auxiliary battery management, where its reverse-battery protection and active clamping protect downstream electronics from harsh fault events. Two channels allow separate control of load and charger paths. The current-sense output gives the BMS a continuous reading of parasitic draw, supporting sleep-mode current budget verification — a common engineering challenge in always-connected vehicles.

설계 노트
At 2 A continuous per channel with 110 mΩ Rds(on), each channel dissipates roughly 0.44 W, giving 0.88 W combined at full dual-channel load. The PG-TSDSO-14 exposed pad must be soldered to a copper pour of at least 200 mm² to keep the junction below 150 °C in still air. In hot underhood or industrial cabinets, derate to 1.3 A per channel or add forced airflow. Estimated: RθJA ≈ 35 °C/W on a 4-layer 2 oz JEDEC test board; verify against the Infineon datasheet curve for your actual PCB.
Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of the Vbb pins and a low-ESR bulk capacitor (≥10 µF) at the supply input to absorb ISO 7637-2 transient pulses. Use wide copper pours (≥2 mm) on the OUT pins, and split logic ground from power ground only if the load current path is independent — for two-channel loads, a single ground pour is fine. The exposed pad must be a continuous copper area without thermal relief cutouts for best thermal performance.
Do not leave IN pins floating — tie them either high or low through a defined resistor (10 kΩ typical) so the channel state is deterministic during MCU startup or reset. The IS pin must be terminated to GND through a sense resistor; an open IS pin is a fault condition and may trigger the device's diagnostic state. Reverse battery (–16 V) survival is rated only when the IC is properly soldered with the exposed pad grounded to the same chassis potential; floating the pad will compromise reverse-battery robustness.
The IS pin output is a current source whose bandwidth extends into the audio range; add a small RC filter (1 kΩ + 100 nF) to filter PWM noise from the ADC sampling. PWM dimming of LED loads should use frequencies above 200 Hz to avoid perceptible flicker and below 2 kHz to stay within the device's switching slew rate. Verify in your specific design because thermal limits depend on PCB copper area.
