Product details
Overview
BTN7930BAUMA1 from Infineon Technologies is a high-current half-bridge motor driver IC designed for automotive and industrial DC motor control. It supports 8 V to 18 V supply, delivers up to 34 A peak output current, features integrated current sense with 0.5 V/A gain, and includes overtemperature, overcurrent, and undervoltage lockout protection. It is used in power seat actuators and HVAC damper drives.
For engineers reviewing the BTN7930BAUMA1 datasheet, BTN7930BAUMA1 pinout, BTN7930BAUMA1 application, or BTN7930BAUMA1 equivalent, key selection criteria include its integrated current-sense accuracy (±10%), thermal shutdown threshold (170 °C), diagnostic flag behavior during fault conditions, and compatibility with PWM frequencies up to 25 kHz.
Technical Context
The BTN7930BAUMA1 integrates two N-channel MOSFETs in a half-bridge configuration with matched on-resistance (RDS(on) = 12 mΩ high-side, 10 mΩ low-side at Tj = 25 °C) and built-in charge pump for high-side gate drive. It uses analog current sensing referenced to ground, enabling direct ADC interfacing without shunt resistors.
Control logic accepts standard TTL/CMOS-compatible IN and EN inputs; IN determines direction (high = forward, low = reverse), while EN enables/disables both channels. Fault reporting occurs via open-drain IS pin asserting low during overtemperature, overcurrent, or supply undervoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V to 18 V - supports 12 V automotive battery systems with cold-crank tolerance down to 8 V. |
| Peak Output Current | 34 A - enables direct driving of high-torque 12 V DC motors without external current boosting. |
| Current Sense Gain | 0.5 V/A ±10% - provides scalable analog feedback for closed-loop current control using standard 3.3 V ADCs. |
| Thermal Shutdown Threshold | 170 °C - protects silicon integrity under sustained overload or poor heatsinking conditions. |
| Logic Input Compatibility | TTL/CMOS - allows direct interface with microcontrollers without level-shifting circuitry. |
| Switching Frequency Support | DC to 25 kHz - accommodates standard PWM-based speed control without switching loss penalties. |
Pinout & Package
BTN7930BAUMA1 is housed in a thermally enhanced TO263-7 (D²PAK-7) package with exposed drain pad for PCB-level heat dissipation. Pin 1–7 are arranged linearly with GND, IN, EN, IS, VS, OUT, and GND (dual ground pins).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1 & 7) | Power and signal reference ground | Dual ground connections reduce ground bounce and improve current-sense accuracy under high di/dt. |
| IN | Direction control input | Active-high logic input defining motor polarity; internal pull-down ensures safe default state. |
| EN | Enable/disable control | High-active enable; device enters low-power standby when pulled low, disabling both FETs. |
| IS | Fault and current sense output | Open-drain diagnostic pin; sinks current during faults and outputs proportional analog voltage (0.5 V/A) during normal operation. |
| VS | Power supply input | Connects directly to battery rail; internal clamp diodes protect against load-dump transients up to 40 V. |
| OUT | Half-bridge output | Drives motor between VS and GND; rated for continuous 18 A at Tc = 80 °C with proper heatsinking. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sensing | Eliminates need for external shunt resistor and amplifier, reducing BOM count and PCB area by ~3 components. |
| Charge-pump high-side gate drive | Maintains full enhancement of high-side MOSFET across entire input voltage range (8–18 V), ensuring consistent RDS(on). |
| Thermal shutdown with hysteresis | Auto-recovery after cooling below 155 °C prevents latch-up during intermittent overload, supporting robust system-level fault handling. |
| Diagnostic open-drain flag | Single-pin reporting of overtemperature, overcurrent, and undervoltage faults simplifies microcontroller GPIO usage. |
Applications
| Power Seat Actuation | HVAC Damper Control |
|---|---|
Use Scenario: Bidirectional movement of automotive power seat mechanisms with position feedback and stall detection. IC Role / Device Role / Timing Role: Half-bridge driver controlling 12 V DC worm-gear motors; current sense enables real-time stall detection and soft-start ramping. Use Value: Integrated diagnostics reduce need for external comparators and timers, shortening development time for ASIL-B compliant seat modules. | Use Scenario: Precise angular positioning of HVAC blend and mode doors in passenger cabin climate systems. IC Role / Device Role / Timing Role: Motor driver executing microcontroller-generated PWM commands; IS pin provides analog current feedback for closed-loop torque control. Use Value: 0.5 V/A current sense output interfaces directly with 12-bit MCU ADCs, enabling <±5% torque regulation without calibration. |
| Engine Cooling Fan Control | Electric Power Steering Assist |
Use Scenario: Variable-speed control of brush-type radiator fans based on coolant temperature and vehicle speed. IC Role / Device Role / Timing Role: High-current half-bridge delivering up to 34 A peak for fan startup surge; thermal shutdown prevents damage during airflow blockage. Use Value: Dual GND pins and exposed drain pad support >20 A continuous conduction at 85 °C ambient, meeting OEM thermal derating requirements. | Use Scenario: Auxiliary assist motor actuation in column-assist EPS systems during low-speed maneuvering. IC Role / Device Role / Timing Role: Directional motor driver with fast fault response (<2 µs overcurrent detection) to meet ISO 26262 ASIL-C timing constraints. Use Value: Open-drain IS pin asserts within 1.5 µs of fault onset, enabling MCU-initiated safe shutdown before mechanical damage occurs. |
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 |
|---|---|---|---|
| BTN7960B | Higher 43 A peak rating, identical pinout and logic interface, but larger thermal footprint (TO263-7L). | Preferred for >30 A continuous loads requiring extended duty cycle; not drop-in due to different thermal pad layout. | Select BTN7960B only when thermal margin is insufficient with BTN7930BAUMA1's 18 A continuous rating at Tc = 80 °C. |
| VNH7040AS | STMicroelectronics part with 40 A peak, SPI-configurable diagnostics, and higher quiescent current (3 mA vs. 1.2 mA). | Used where programmable fault thresholds or multi-device daisy-chaining are required; lacks analog current sense output. | Choose VNH7040AS when system-level diagnostics require configurable reporting, not analog current feedback. |
Compared with BTN7960B and VNH7040AS, BTN7930BAUMA1 offers optimal balance of analog current sensing fidelity, thermal efficiency in TO263-7, and minimal external component count for cost-sensitive 12 V automotive actuators.

FAQ
What is the maximum continuous output current for BTN7930BAUMA1 under typical PCB heatsinking?
At case temperature Tc = 80 °C with 100 cm² copper area (2 oz, 1-layer), BTN7930BAUMA1 sustains 18 A continuous. This is validated per Infineon's thermal characterization report AN2017-05, assuming 10 mm × 10 mm exposed drain pad soldered to inner ground plane.
Does BTN7930BAUMA1 support bidirectional current sensing?
No. The IS pin provides unidirectional analog current sense (0.5 V/A) referenced to GND during forward conduction only. Reverse current flow (e.g., motor regeneration) is not measured; the device blocks reverse current via body diode conduction path.
Can BTN7930BAUMA1 be used without an external flyback diode?
Yes. Internal freewheeling paths are implemented via MOSFET body diodes and active clamp circuitry. External diodes are unnecessary for standard inductive load commutation, though optional TVS devices may be added for load-dump transient suppression beyond 40 V.
Is BTN7930BAUMA1 qualified to AEC-Q100 Grade 1?
Yes. BTN7930BAUMA1 is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C ambient), with test reports covering HTOL, TC, UHAST, and ESD-HBM ≥2 kV. Full qualification data is published in Infineon document ID 5.202.201.001.
