Product details
Overview
BTN7963BAUMA1 from Infineon Technologies is a high-current monolithic half-bridge driver IC designed for robust motor control in automotive and industrial applications. It delivers 44 A continuous output current, operates from 5.5 V to 28 V supply, integrates integrated current sense with ±5% accuracy, features overtemperature shutdown, and is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C). It drives DC motors, solenoids, and resistive loads in engine cooling fans.
For engineers reviewing the BTN7963BAUMA1 datasheet, BTN7963BAUMA1 pinout, BTN7963BAUMA1 application, or BTN7963BAUMA1 equivalent, key selection criteria include its integrated current-sense accuracy, thermal shutdown threshold at 175 °C, IN/EN logic interface compatibility with 3.3 V/5 V microcontrollers, and TO263-7 package thermal performance under forced-air convection.
Technical Context
The BTN7963BAUMA1 implements dual N-channel MOSFET half-bridge topology with integrated gate drivers, bootstrap circuitry, and analog current-sense amplifier. Its internal charge pump enables high-side NMOS operation without external components, and the integrated diagnostic flag (IS) provides real-time overcurrent/overtemperature status.
It supports PWM switching up to 25 kHz with propagation delay of 1.2 µs (typ.) and rise/fall times ≤ 1.5 µs. The device uses embedded protection including undervoltage lockout (UVLO), short-circuit detection via current-sense threshold, and latch-off behavior after fault detection until reset via EN pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 44 A continuous (TC = 25 °C, PCB copper area ≥ 200 cm²); enables direct drive of high-power 12 V/24 V DC motors without external heatsink. |
| Supply Voltage Range | 5.5 V to 28 V; supports wide automotive battery range including cold-crank (6.5 V) and load-dump (28 V) conditions. |
| Current Sense Accuracy | ±5% (−40 °C to +125 °C); allows precise closed-loop motor current regulation without external shunt calibration. |
| Thermal Shutdown Threshold | 175 °C (junction); latches off until EN deasserted, preventing thermal runaway in stalled-motor scenarios. |
| Logic Input Compatibility | 3.3 V / 5 V CMOS/TTL; eliminates level-shifter requirement when interfacing with modern MCUs like S32K or TC3xx families. |
| Propagation Delay | 1.2 µs (typ.); ensures tight timing control for high-frequency PWM motor commutation. |
Pinout & Package
BTN7963BAUMA1 is housed in a thermally enhanced TO263-7 (D2PAK-7) surface-mount package with exposed drain pad for low thermal resistance (RthJA = 20 K/W on 2-layer 200 cm² PCB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS | Power supply input | Connects to battery rail (5.5–28 V); feeds both high-side and low-side power stages. |
| GND | Power ground | Common return path for load current and logic; must be low-inductance connection to minimize noise coupling. |
| IN | Input control signal | Active-high logic input controlling high-side switch; compatible with 3.3 V/5 V MCU GPIO. |
| EN | Enable input | Active-high enable; resets fault latches and powers internal logic; pulled low disables all outputs. |
| OUT | Half-bridge output | Switching node connecting to motor terminal; rated for 44 A continuous and 80 A peak surge. |
| IS | Current sense output | Analog voltage proportional to load current (VIS = 0.2 V/A); used for real-time monitoring and overcurrent protection. |
| BOOT | Bootstrap capacitor connection | Connects external 100 nF ceramic capacitor to enable high-side NMOS gate drive above VS. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sense | Eliminates external shunt resistor and op-amp circuitry, reducing BOM count and PCB area by >30% in fan control designs. |
| Embedded thermal protection | Latch-off behavior at 175 °C junction prevents repeated fault cycling, enabling fail-safe motor stop in overheating conditions. |
| Bootstrap-based high-side drive | Removes need for isolated supply or charge-pump IC, simplifying layout and improving reliability in space-constrained modules. |
| AEC-Q100 Grade 1 qualification | Validated for automotive under-hood environments (−40 °C to +125 °C ambient), supporting engine cooling, HVAC blower, and radiator fan applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics L99H02 | 40 A continuous rating; requires external current-sense amplifier; no integrated IS output. | Targeted at cost-sensitive non-AEC-Q100 industrial actuators; lacks automotive-grade thermal robustness. | Select when BOM cost is primary constraint and closed-loop current sensing is implemented externally. |
| Texas Instruments DRV8876N | 35 A continuous; integrated current sense (±8%); 5 V logic only; no AEC-Q100 qualification. | Designed for consumer robotics and medical pumps; not validated for automotive under-hood vibration or temperature cycling. | Select for non-automotive 24 V motion control where footprint and 5 V MCU compatibility outweigh thermal margin needs. |
Compared with L99H02 and DRV8876N, BTN7963BAUMA1 uniquely combines AEC-Q100 Grade 1 qualification, ±5% current-sense accuracy, and 44 A continuous output in a single TO263-7 package-making it the only choice for production automotive cooling fan modules requiring zero-field-failure reliability.

FAQ
What is the maximum PWM frequency supported by BTN7963BAUMA1?
The BTN7963BAUMA1 supports PWM switching up to 25 kHz with guaranteed timing performance. At this frequency, propagation delay remains 1.2 µs (typ.), and rise/fall times stay ≤1.5 µs. Operation beyond 25 kHz is possible but may reduce current capability due to increased switching losses and thermal constraints-design validation required per application PCB layout and heatsinking.
Does BTN7963BAUMA1 require an external bootstrap diode?
No, the BTN7963BAUMA1 integrates an internal bootstrap diode. Only an external 100 nF ceramic capacitor between BOOT and OUT is required to sustain high-side gate drive. This eliminates discrete diode placement and associated layout sensitivity, improving design robustness and reducing bill-of-materials count in automotive motor modules.
How does the IS pin output scale with load current?
The IS pin delivers a voltage output of 0.2 V per ampere of load current (VIS = 0.2 × ILOAD), with ±5% accuracy over −40 °C to +125 °C. For example, 20 A load yields 4.0 V ±0.2 V at IS. This ratiometric scaling enables direct ADC measurement without gain calibration in MCU-based motor controllers.
Can BTN7963BAUMA1 drive inductive loads without external flyback protection?
Yes-the BTN7963BAUMA1 integrates clamp diodes across both high- and low-side MOSFETs, enabling safe energy recirculation during inductive turn-off. No external freewheeling diodes are required for standard DC motor or solenoid loads. However, external TVS clamping is recommended for systems subject to ISO 7637-2 pulse 5a (load dump) transients exceeding 40 V.
