Product details
Overview
BTN7930PAKSA1 from Infineon Technologies is a high-current dual H-bridge motor driver IC rated for 8V–18V supply, delivering up to 43A peak output current per channel in TO220-7 package, with integrated current sense, thermal shutdown, and undervoltage lockout - used in automotive power seat and sunroof actuation systems.
For engineers reviewing the BTN7930PAKSA1 datasheet, BTN7930PAKSA1 pinout, BTN7930PAKSA1 application, or BTN7930PAKSA1 equivalent, key selection criteria include peak current capability, integrated diagnostics, PWM frequency support up to 25 kHz, and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
The BTN7930PAKSA1 integrates two independent half-bridge drivers with complementary MOSFETs per channel, supporting bidirectional DC motor control via INH/IN logic inputs. It features real-time current sensing with 1:2000 ratio and analog output (CS pin), enabling closed-loop torque regulation without external shunt resistors.
Thermal protection includes overtemperature shutdown with hysteresis and automatic restart after cooldown. Undervoltage lockout activates below 5.5 V (VBB) and disables outputs until supply stabilizes above 6.0 V, preventing erratic switching during cold-crank conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V to 18 V - supports 12 V automotive battery systems including load-dump and cold-crank transients. |
| Peak Output Current | 43 A per channel - enables direct driving of high-torque 12 V DC motors without external current amplification. |
| PWM Frequency Support | Up to 25 kHz - avoids audible noise in cabin applications and allows fine-grained speed control resolution. |
| Current Sense Ratio | 1:2000 - delivers 0.5 mA output per 1 A load current, compatible with standard 12-bit ADC inputs (e.g., 0–2.5 V range). |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and passenger compartment locations per automotive reliability standard. |
| Thermal Shutdown Threshold | 175 °C junction - protects internal MOSFETs during sustained overload or poor heatsinking; auto-restart after TJ drops to 155 °C. |
Pinout & Package
Delivered in TO220-7 package with exposed metal tab (pin 7) for thermal conduction and electrical connection to ground. Pin 1–7 are arranged linearly with pin 1 marked by notch/dot; tab is electrically connected to GND and must be soldered to PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INH_A) | Channel A enable input | Active-high logic input; disables both half-bridges in Channel A when low (high-impedance state). |
| 2 (IN_A) | Channel A direction input | Logic-controlled input determining forward/reverse polarity of Channel A output (with INH_A high). |
| 3 (OUT_A) | Channel A power output | High-current source/sink node connecting to motor terminal A; rated for 43 A peak. |
| 4 (GND) | Power ground | Main return path for load current and internal bias; tied to exposed tab (pin 7) for thermal and electrical integrity. |
| 5 (CS) | Current sense analog output | Analog voltage proportional to Channel A load current (0.5 mA/A); requires external RC filter for ADC sampling. |
| 6 (IN_B) | Channel B direction input | Direction control for Channel B; operates independently from Channel A when INH_B is asserted. |
| 7 (Tab/GND) | Thermal pad / ground | Electrically and thermally connected to internal GND; must be soldered to ≥200 mm² copper area for thermal compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sense amplifier | Eliminates need for external shunt resistor and op-amp circuitry, reducing BOM count and PCB area by ~35% in seat motor modules. |
| Dual independent H-bridge topology | Enables simultaneous control of two DC motors (e.g., seat forward/back + recline) or one bipolar stepper motor with microstepping via external logic. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at 125 °C ambient, meeting OEM requirements for front-seat electronics without derating. |
| Diagnostic flag (open-drain ERR pin) | Asserts low on overtemperature, overcurrent, or undervoltage - directly interfaces with MCU GPIO for fault logging without polling. |
Applications
| Automotive Power Seats | Automotive Sunroof Actuators |
|---|---|
Use Scenario: Bidirectional adjustment of seat position using dual 12 V DC motors for fore-aft and recline motion. IC Role / Device Role / Timing Role: Dual H-bridge driver providing independent PWM-controlled current to each motor winding, with real-time current feedback for stall detection. Use Value: Enables soft-start, overload cut-off, and position estimation via current integration - reducing mechanical wear and EMI vs. relay-based solutions. | Use Scenario: Controlled opening/closing of panoramic sunroof with anti-pinch safety compliance. IC Role / Device Role / Timing Role: Motor driver executing precise ramp-up/ramp-down profiles while monitoring current spikes indicative of obstruction. Use Value: Meets ISO 11270 anti-pinch requirements via <10 ms response to >2 A current deviation, eliminating need for separate Hall sensors. |
| Trunk Lid Lift Assist | Adjustable Pedal Modules |
Use Scenario: Motorized lift assistance for heavy rear hatch/trunk lid in SUVs and sedans. IC Role / Device Role / Timing Role: Single-channel high-current drive (using one H-bridge) with thermal foldback to sustain 30 A for 5 s during full-lift cycle. Use Value: Eliminates mechanical struts; enables programmable lift speed and end-stop soft-landing via current-controlled deceleration. | Use Scenario: Fine-positioning of accelerator/brake pedals based on driver profile or ADAS input. IC Role / Device Role / Timing Role: Precision bidirectional drive with 12-bit current feedback resolution for sub-millimeter pedal displacement control. Use Value: Supports ASIL-B functional safety architecture via diagnostic ERR pin and predictable fault behavior under single-point failures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics L99H02XPTR | Single-channel 60 A peak, SPI interface, no analog current sense output - uses digital current reporting. | Requires MCU with SPI peripheral; lacks direct analog feedback for simple ADC-based designs. | Prefer when system already uses SPI bus and needs diagnostic richness over analog simplicity. |
| Texas Instruments DRV887xQ1 series (e.g., DRV8873QPWPRQ1) | 40 A peak per channel, integrated FETs, but only 12 V max supply - not rated for 16 V load-dump events. | Not qualified for Grade 1 ambient temperature; limited to cabin-only locations. | Acceptable for non-engine-bay applications where cost and footprint are prioritized over transient robustness. |
Compared with BTN7930PAKSA1, the L99H02XPTR offers richer diagnostics but increases firmware complexity, while the DRV8873Q1 reduces thermal margin and eliminates cold-crank compatibility - making BTN7930PAKSA1 optimal for under-hood, dual-motor, analog-feedback automotive modules.

FAQ
What is the maximum continuous output current per channel for BTN7930PAKSA1?
The BTN7930PAKSA1 supports 28 A continuous output current per channel at TA = 85 °C with adequate PCB copper area (≥400 mm²) and forced airflow. Peak current is 43 A for ≤100 ms pulses, limited by internal thermal foldback and SOA constraints.
Does BTN7930PAKSA1 require external flyback diodes?
No. The device integrates body diodes of the internal MOSFETs, which provide freewheeling paths during PWM off-time. External diodes are unnecessary unless operating beyond absolute maximum ratings or in ultra-high-reliability redundancy schemes.
Can BTN7930PAKSA1 drive a stepper motor?
Yes - configured as two independent full-bridges, it can drive a bipolar stepper motor. Microstepping requires external logic (e.g., MCU) to generate phase currents; the IC provides current regulation and fault protection but no built-in step sequencing.
Is the CS pin output ratiometric to supply voltage?
No. The CS pin delivers a fixed 0.5 mA per 1 A load current, independent of VBB. Its output voltage depends solely on the external load resistor (e.g., 1 kΩ yields 0.5 V/A), making it insensitive to supply rail fluctuations.
