Product details
Overview
BTS7750GNUMA1 from Infineon Technologies is a high-current monolithic half-bridge driver IC designed for robust 12 V automotive powertrain and chassis applications. It integrates two N-channel MOSFETs with embedded charge pump, thermal shutdown, overcurrent protection, and diagnostic feedback. Typical use includes driving solenoids, valves, and small DC motors in engine control modules and transmission actuators.
For engineers reviewing the BTS7750GNUMA1 datasheet, BTS7750GNUMA1 pinout, BTS7750GNUMA1 application, or BTS7750GNUMA1 equivalent, key selection criteria include continuous current rating (50 A), integrated diagnostics (open-load/short-to-battery/short-to-ground detection), supply voltage range (5.5–28 V), and AEC-Q100 Grade 1 qualification.
Technical Context
The BTS7750GNUMA1 implements a dual-N-channel half-bridge topology with integrated bootstrap gate driver and internal charge pump enabling high-side switching without external components. It features real-time current sensing via proportional analog output (IS) and supports PWM operation up to 25 kHz.
Protection architecture includes overtemperature shutdown with hysteresis, overcurrent limiting with fast response (< 2 µs), reverse battery protection, and ESD immunity per ISO 10605 (±8 kV contact). All protections trigger diagnostic flag (nFAULT) assertion and automatic latch-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 50 A - supports high-power solenoid actuation without external heatsink in typical 12 V automotive ambient |
| Supply Voltage Range | 5.5 V to 28 V - compatible with cold-crank (6.0 V) and load-dump (27.5 V) conditions per ISO 16750-2 |
| Diagnostic Output | Analog current sense (IS) + digital nFAULT - enables real-time current monitoring and fault classification in ECU firmware |
| Protection Features | Overcurrent, overtemperature, open-load, short-to-battery, short-to-ground - reduces need for external supervision circuitry |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and transmission control unit mounting locations |
| Switching Frequency | DC to 25 kHz - supports precise PWM-controlled torque modulation in electro-hydraulic valve actuators |
Pinout & Package
Package: PG-DSO-28-19 (exposed thermal pad, RoHS-compliant, lead-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V battery rail; supports transient overvoltage up to 41 V |
| GND | Power and signal ground | Dual GND pins (pins 1, 28) reduce ground loop impedance and improve noise immunity |
| IN | Logic-level input control | CMOS-compatible (2.0 V min high, 0.8 V max low); accepts 3.3 V or 5 V microcontroller signals |
| OUT | Half-bridge output terminal | Drives inductive loads directly; rated for 50 A continuous, 100 A peak (10 ms) |
| IS | Analog current sense output | 0.2% of load current (e.g., 100 mV/A); enables closed-loop current regulation without shunt resistor |
| nFAULT | Open-drain fault indicator | Pulls low on any active protection event; requires external pull-up for ECU interrupt detection |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables 100% duty-cycle high-side NMOS operation without external bootstrap capacitor or diode |
| Proportional current sense (IS) | Eliminates need for precision shunt resistor and differential amplifier in current feedback loops |
| Fast overcurrent response (< 2 µs) | Prevents MOSFET destruction during short-circuit events before ECU can react |
| Reverse battery protection | Withstands −16 V applied to VBB without damage or latch-up - critical for service/maintenance scenarios |
| Thermal shutdown with hysteresis | Shuts down at 175 °C junction, restarts at 155 °C - prevents thermal runaway in confined enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics VNQ7050AJTR | Lower continuous current (28 A), no analog IS output - only digital current threshold flag | Suitable for lower-power solenoids but lacks closed-loop current control capability | Select when cost sensitivity outweighs need for analog current feedback and higher current headroom |
| NXP MC33883AEP | Higher RDS(on) (12 mΩ vs. 8.5 mΩ), no reverse battery protection, requires external bootstrap capacitor | Compatible with legacy designs using discrete bootstrap networks; less robust in service environments | Choose only if existing layout accommodates external bootstrap and thermal margin permits higher conduction loss |
Compared with VNQ7050AJTR and MC33883AEP, BTS7750GNUMA1 offers superior current capability, integrated diagnostics with analog sensing, and enhanced system-level robustness - making it optimal for next-generation powertrain actuators requiring functional safety support.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The BTS7750GNUMA1 has a maximum junction temperature of 175 °C, with thermal shutdown activated at this threshold. Operation above 155 °C triggers hysteresis-based recovery, allowing safe restart after cooling. Derating curves in the datasheet specify 50 A continuous current only at Tj ≤ 150 °C with proper PCB copper area (≥ 400 mm² thermal pad exposure).
Does BTS7750GNUMA1 support bidirectional current flow?
No - BTS7750GNUMA1 is a unidirectional high-side/low-side half-bridge driver optimized for driving inductive loads in one direction. It does not support true H-bridge reversal or regenerative energy return to the supply rail. For bidirectional motor control, two BTS7750GNUMA1 devices must be used in complementary configuration with external logic.
Can the IS pin be used for closed-loop current regulation?
Yes - the IS pin delivers a proportional analog voltage (100 mV/A ±5%) referenced to GND, enabling direct ADC sampling by an automotive MCU. This allows real-time current regulation without external shunt resistors, provided the MCU's ADC reference and sampling rate meet the 25 kHz PWM bandwidth requirement.
Is external bootstrap capacitor required for high-side operation?
No - the integrated charge pump eliminates the need for an external bootstrap capacitor or diode. This simplifies PCB layout, improves reliability under vibration, and ensures stable high-side gate drive even at 0% duty cycle, unlike discrete bootstrap solutions that fail below ~10% minimum on-time.
