Product details
Overview
BTS7750GP from Infineon Technologies is a high-current dual-channel high-side power switch IC designed for 12 V automotive applications. It integrates two independent protected high-side switches in a single TO263-15 package, supports up to 60 V supply voltage, delivers continuous 40 A per channel (with pulse capability up to 80 A), and features integrated current sensing, overtemperature shutdown, and load-dump protection. It is used in engine control modules for driving solenoids and fuel injectors.
For engineers reviewing the BTS7750GP datasheet, BTS7750GP pinout, BTS7750GP application, or BTS7750GP equivalent, key selection considerations include channel independence, real-time current sense accuracy (±5% typical), diagnostic flag resolution per channel, and compliance with ISO 7637-2 and ISO 16750-2 automotive transient standards.
Technical Context
The BTS7750GP implements two fully independent high-side driver channels with separate INx inputs, ISx current sense outputs, and FLTx fault flags. Each channel includes active current limiting, thermal foldback, and open-load detection via high-impedance pull-up on ISx pins.
It operates across -40 °C to +150 °C ambient temperature, supports PWM switching up to 25 kHz, and provides reverse-battery protection down to -28 V. The device uses bipolar technology with integrated lateral DMOS power stages and embedded analog monitoring circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 60 V - Supports full automotive battery range including cold-crank (4.5 V) and load-dump transients (60 V) |
| Continuous Current per Channel | 40 A - Enables direct drive of high-power solenoids without external heatsinking at TA = 85 °C |
| Current Sense Accuracy | ±5 % (typ.) - Enables precise closed-loop current regulation and fault threshold setting |
| On-State Resistance (RDS(on)) | 9 mΩ (max) - Limits conduction loss to ≤14.4 W per channel at 40 A |
| Fault Flag Response Time | ≤ 2 µs - Allows fast system-level shutdown before wire harness damage occurs |
| Diagnostic Resolution | Per-channel FLTx and ISx - Enables independent channel health monitoring in multi-actuator systems |
Pinout & Package
Package: TO263-15 (D²PAK-15), thermally enhanced surface-mount package with exposed drain pad for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V battery rail; internal clamping protects against load-dump transients |
| GND | Power and signal ground reference | Common return path for both channels and internal diagnostics; requires low-inductance layout |
| IN1 / IN2 | Digital enable inputs | 3.3 V/5 V compatible TTL/CMOS logic; each controls respective channel independently |
| OUT1 / OUT2 | High-side switched outputs | Drives inductive loads directly; integrated freewheeling path eliminates need for external flyback diodes |
| IS1 / IS2 | Analog current sense outputs | 0.5 V/A scaling enables direct ADC interface; ±5 % accuracy supports ASIL-B functional safety |
| FLT1 / FLT2 | Open-drain fault flags | Assert low on overcurrent, overtemperature, or open-load; pulled up externally to VBB |
| EN | Global enable input | Disables both channels simultaneously; required for system-level safety interlock |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Enables redundant or parallel actuator control without cross-talk; supports ASIL-D decomposition |
| Integrated current sense with ±5 % accuracy | Eliminates external shunt resistors and amplifiers; reduces BOM count and layout area by ≥30 % |
| Load-dump protection up to 60 V | Meets ISO 7637-2 Pulse 5a requirements without external TVS; simplifies front-end protection design |
| Per-channel diagnostic flag and sense output | Supports ISO 26262-compliant fault tree analysis with no shared failure modes between channels |
Applications
| Fuel Injector Driver | Transmission Solenoid Control |
|---|---|
Use Scenario: Precise timing and current-controlled injection in gasoline direct injection (GDI) engines. IC Role / Device Role / Timing Role: High-side power switch with real-time current feedback for closed-loop injector current ramp control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics VND7050AJ | Single-channel, 50 A peak, 12 mΩ RDS(on), no integrated current sense scaling | Lacks dual-channel integration and factory-trimmed IS output; requires external amplifier | Select when only one high-side switch is needed and cost-per-channel is prioritized over integration |
| NXP MC33883 | Dual-channel, but rated for 20 A continuous, 25 mΩ RDS(on), no load-dump protection beyond 40 V | Not qualified for 60 V load-dump; requires external TVS for ISO 7637-2 compliance | Choose for lower-power chassis modules where thermal budget allows higher RDS(on) |
Compared with VND7050AJ and MC33883, BTS7750GP uniquely delivers dual 40 A channels with integrated ±5 % current sense and 60 V load-dump immunity-reducing system-level protection components and enabling ASIL-B–compliant designs in a single package.

FAQ
What is the maximum allowable junction temperature for BTS7750GP?
The absolute maximum junction temperature is +175 °C. Operation above +150 °C triggers thermal shutdown with hysteresis; derating curves in the datasheet define safe continuous current versus board copper area and airflow. Thermal resistance RthJA is 1.8 K/W on 100 mm² 2-oz copper with 10 LFM airflow.
Does BTS7750GP support PWM switching, and what is its maximum frequency?
Yes, BTS7750GP supports PWM operation up to 25 kHz. Rise/fall times are 1.2 µs and 1.5 µs respectively at ILOAD = 40 A, VBB = 13.5 V, and TA = 25 °C. Higher frequencies increase switching losses and require careful gate drive strength optimization.
How is open-load detection implemented, and what is its response time?
Open-load detection uses internal high-impedance pull-up on ISx pins; when no load is connected, ISx rises to ~0.8 × VBB, triggering FLTx after 100 µs. Detection works only with INx high and no overtemperature condition. Response time is fixed and does not vary with supply voltage.
Can BTS7750GP be used in 24 V commercial vehicle applications?
Yes-its 4.5 V to 60 V operating range covers nominal 24 V systems, including cranking dips and ISO 16750-2 transients. However, continuous current must be derated: 32 A per channel at TA = 85 °C for 24 V use due to higher conduction loss at elevated VBB.
