Product details
Overview
BTN8960TAAUMA1 from Infineon Technologies is a high-current monolithic half-bridge driver IC designed for automotive motor control, featuring 30 A continuous output current, integrated high-side and low-side MOSFETs, overtemperature and short-circuit protection, and operation up to 40 V supply voltage. It drives brushed DC motors in power seat, sunroof, and HVAC actuators.
For engineers reviewing the BTN8960TAAUMA1 datasheet, BTN8960TAAUMA1 pinout, BTN8960TAAUMA1 application, or BTN8960TAAUMA1 equivalent, key selection criteria include peak current capability (60 A), integrated diagnostics (open-load, overcurrent, thermal warning), PWM switching frequency support (up to 25 kHz), and AEC-Q100 Grade 1 qualification for under-hood use.
Technical Context
The BTN8960TAAUMA1 integrates complementary N-channel power MOSFETs with adaptive gate driving, real-time current sensing via proportional current mirror, and digital diagnostic reporting through a dedicated INH/IS pin. Its internal charge pump enables 100% duty-cycle operation without external bootstrap components.
It implements dual-stage overtemperature protection (warning at 150 °C, shutdown at 175 °C), supports both enable-based and PWM-based control modes, and features fast current-limit response (< 2 µs) with adjustable blanking time for noise immunity in noisy automotive environments.
Key Specifications

Applications
| Power Seat Actuation | Sunroof Motor Control |
|---|---|
Use Scenario: Bidirectional movement of automotive power seat mechanisms with position feedback and soft-start. IC Role / Device Role / Timing Role: Half-bridge driver providing controlled H-bridge polarity reversal and current-limited acceleration/deceleration. Use Value: Integrated diagnostics reduce ECU software overhead for fault detection; 30 A rating handles high-inertia seat track loads. | Use Scenario: Smooth, quiet opening/closing of panoramic sunroofs with anti-pinch compliance. IC Role / Device Role / Timing Role: PWM-controlled bidirectional motor driver with precise current regulation for speed and torque consistency. Use Value: 25 kHz switching enables ultrasonic PWM operation, eliminating audible whine during normal operation. |

Use Value: Fast (< 2 µs) current-limit response prevents thermal runaway during blade obstruction or icing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTN8982TA | Higher RDS(on) (12 mΩ vs. 9.5 mΩ), lower peak current (50 A), same package and pinout | Targeted at lower-power HVAC and mirror actuation; reduced thermal margin at 30 A continuous | Select when cost sensitivity outweighs peak current headroom and thermal performance is verified for target load |
| TPIC2603D | External MOSFET driver (not integrated), no current sense, higher external component count | Used where discrete FET selection is required for ultra-low RDS(on) or high-voltage (>40 V) operation | Choose only if system-level flexibility in FET selection or voltage scaling beyond 40 V is mandatory |
Compared with BTN8982TA and TPIC2603D, BTN8960TAAUMA1 delivers superior continuous current capability and integrated diagnostics-critical for ASIL-B-compliant seat and sunroof modules-while reducing bill-of-materials complexity and PCB footprint.

FAQ
What is the maximum allowable PCB copper area for thermal relief on the exposed drain pad?
The TO263-7 package requires ≥200 mm² of 2-oz copper connected to the exposed drain pad via ≥6 thermal vias (0.3 mm diameter, filled or plated). This achieves ≤3.5 K/W junction-to-board thermal resistance, enabling 30 A continuous operation at 85 °C ambient per Infineon Application Note AN2019-04.
Does BTN8960TAAUMA1 support reverse battery protection?
No. BTN8960TAAUMA1 lacks integrated reverse-polarity protection and must be used with an external series Schottky diode or MOSFET-based protection circuit. Reverse battery events below −18 V will damage the device, as confirmed in the Absolute Maximum Ratings table of the official datasheet Rev. 2.0.
Can the INH/IS pin be used for closed-loop current control without external amplification?
Yes. The IS function provides a proportional current mirror output (1:2000) with ±5% accuracy from 0.5 A to 30 A. It interfaces directly with a 12-bit ADC (≥1 V full-scale range) for real-time current monitoring and PID control without op-amps or shunt resistors.
Is there a recommended minimum dead-time setting when using external PWM generation?
Infineon specifies a minimum 1.2 µs dead-time between high-side and low-side drive signals to prevent shoot-through. This value is validated across temperature and voltage extremes and must be enforced in MCU firmware or external logic-no internal dead-time generator is present in BTN8960TAAUMA1.
