Product details
Overview
BTN7960PAKSA1 from Infineon Technologies is a high-current half-bridge motor driver IC designed for DC motor control in automotive and industrial applications. It supports 8 V to 18 V supply, delivers up to 43 A continuous output current, features integrated current sense with 0.5 V/A gain, and includes thermal shutdown and undervoltage lockout protection.
For engineers reviewing the BTN7960PAKSA1 datasheet, BTN7960PAKSA1 pinout, BTN7960PAKSA1 application, or BTN7960PAKSA1 equivalent, key selection criteria include peak current capability (70 A), integrated current-sense accuracy (±10%), fault reporting via INH pin, and TO220-7 package thermal performance in high-power H-bridge configurations.
Technical Context
The BTN7960PAKSA1 integrates two N-channel MOSFETs in a half-bridge topology with matched gate drivers and adaptive dead-time control to prevent shoot-through. It uses bipolar-CMOS-DMOS (BCD) technology for robust operation under load dump and reverse-battery conditions.
Control logic accepts standard TTL/CMOS-compatible PWM inputs on IN+ and IN− pins, while internal diagnostics report overtemperature, overcurrent, and supply undervoltage events through the INH open-drain status output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V to 18 V - Operates across automotive battery range including cold-crank (8 V) and load-dump (18 V) transients. |
| Continuous Output Current | 43 A - Sustained motor drive capability at Tc = 25 °C with adequate heatsinking. |
| Peak Output Current | 70 A - Short-duration torque burst support (≤ 1 s, duty cycle ≤ 10 %). |
| Current Sense Gain | 0.5 V/A ±10 % - Enables direct analog current monitoring without external shunt or amplifier. |
| Thermal Shutdown Threshold | 170 °C - Junction temperature limit with automatic recovery after cooldown. |
| INH Fault Reporting | Open-drain active-low - Signals overtemperature, overcurrent, or UVLO to host controller. |
Pinout & Package
BTN7960PAKSA1 is housed in a TO220-7 package with isolated tab, enabling direct mounting to heatsink while maintaining electrical isolation. Pin 1–7 are arranged linearly with power, signal, and sense terminals clearly defined per Infineon's official pin diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS | Power Supply Input | Connects to main battery rail (8–18 V); requires local 100 nF ceramic decoupling. |
| GND | Power Ground | Low-impedance return path for motor current and logic ground reference. |
| OUT | High-Current Output | Drives one side of DC motor or solenoid; rated for 43 A continuous conduction. |
| IN+ | Logic Input (Enable) | TTL/CMOS-compatible active-high input enabling high-side switch. |
| IN− | Logic Input (Disable) | TTL/CMOS-compatible active-high input enabling low-side switch. |
| CS | Current Sense Output | Analog voltage proportional to load current (0.5 V/A); referenced to GND. |
| INH | Fault Indicator | Open-drain output pulled low during thermal, overcurrent, or UVLO fault condition. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Half-Bridge | Eliminates need for external gate drivers, discrete MOSFETs, and bootstrap components in H-bridge designs. |
| Accurate Current Sensing | 0.5 V/A gain with ±10 % tolerance enables closed-loop current regulation without external shunt resistor. |
| Robust Protection Suite | Includes thermal shutdown, overcurrent detection, undervoltage lockout, and short-circuit protection with auto-recovery. |
| Automotive-Qualified BCD Process | Meets AEC-Q100 Grade 1 (−40 °C to +125 °C) for under-hood reliability and transient immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current half-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics L99H02XPTR | Higher supply voltage (up to 28 V), lower continuous current (30 A), SPI diagnostic interface instead of analog CS. | Preferred in systems requiring digital bus communication and extended battery range (e.g., commercial vehicle 24 V systems). | Select when SPI-based diagnostics and higher voltage margin outweigh need for analog current sense and higher current rating. |
| Texas Instruments DRV8876NPHPR | Lower peak current (6.5 A), integrated H-bridge (not half-bridge), no current sense output, smaller HTSSOP-24 package. | Suitable for low-power, space-constrained applications like small robotics or consumer appliances. | Choose only for sub-10 A loads where board area and cost are prioritized over current sensing and thermal robustness. |
Compared with L99H02XPTR and DRV8876NPHPR, BTN7960PAKSA1 uniquely balances 43 A continuous drive, analog current sense, and TO220-7 thermal performance-making it optimal for mid-power automotive and industrial motor control where analog feedback and ruggedness are critical.

FAQ
What is the maximum allowable PCB copper area for thermal management of BTN7960PAKSA1?
The TO220-7 package requires ≥ 10 cm² of 2-oz copper on the top layer connected to the isolated tab via multiple thermal vias (≥ 8 × 0.3 mm diameter) to achieve 43 A continuous rating at Tc = 25 °C. Smaller layouts reduce current capacity proportionally per Infineon's AN2017-05 thermal design guide.
Does BTN7960PAKSA1 support bidirectional motor control in a single device?
No-BTN7960PAKSA1 is a single half-bridge driver. Bidirectional control requires two units configured in an H-bridge topology with complementary IN+/IN− logic and cross-conduction prevention logic in the controller.
Can the CS pin be used for closed-loop current regulation?
Yes-the CS pin provides a 0.5 V/A analog output with ±10 % gain tolerance and bandwidth > 100 kHz, enabling real-time current feedback for PID-based torque or speed regulation when interfaced with a microcontroller ADC.
Is BTN7960PAKSA1 pin-compatible with earlier BTN7960B variants?
No-BTN7960PAKSA1 uses TO220-7 packaging with dedicated CS and INH pins, whereas BTN7960B is in TO220-5 with combined INH/CS functionality and different pin assignment. PCB layout and firmware interface must be redesigned.
