Product details

Overview

BTN7930S from Infineon Technologies is a high-current half-bridge motor driver IC designed for automotive and industrial DC motor control. It operates from 8 V to 18 V supply, delivers up to 30 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, HVAC damper drives, and electronic throttle control systems.

For engineers reviewing the BTN7930S datasheet, BTN7930S pinout, BTN7930S application, or BTN7930S equivalent, key selection criteria include its 30 A peak drive capability, integrated current sensing accuracy, thermal shutdown threshold of 170 °C, and diagnostic flag signaling for fault conditions.

Technical Context

The BTN7930S integrates two N-channel MOSFETs in a half-bridge configuration with adaptive dead-time control to prevent shoot-through. It uses a charge-pump circuit to sustain high-side gate drive above supply voltage, enabling 100% duty-cycle operation.

Internal diagnostics monitor load current via an analog sense output (IS), detect open-load and short-to-ground/short-to-supply faults, and report status through a dedicated INH/FLT pin that toggles between active-low fault indication and high-impedance normal operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	8 V to 18 V - supports standard 12 V automotive battery systems with tolerance for load-dump transients.
Peak Output Current	30 A - enables direct driving of high-torque 12 V DC motors without external current boosting.
Current Sense Gain	0.5 V/A - provides linear analog feedback for closed-loop current regulation with ±5% accuracy.
Thermal Shutdown Threshold	170 °C - protects silicon integrity during sustained overload or poor heatsinking conditions.
Logic Input Compatibility	3.3 V / 5 V CMOS - interfaces directly with microcontrollers without level-shifting circuitry.
Diagnostic Flag Output	INH/FLT pin - signals fault condition as active-low open-drain output with internal pull-up.

Pinout & Package

BTN7930S is housed in a TO-220-7 package with exposed thermal pad for enhanced heat dissipation. The package requires mechanical mounting to a heatsink and soldering of the thermal pad to PCB copper for optimal thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
V_S	Power supply input	Connects to 8–18 V battery rail; feeds both high-side and low-side MOSFETs.
GND	Power ground	Common return path for load current and internal logic; must be low-inductance connection.
IN	Control input	CMOS-compatible digital input controlling high-side MOSFET turn-on/turn-off sequence.
INH/FLT	Enable/fault indicator	Active-low open-drain output indicating device enable state or fault condition (overtemp, overcurrent).
IS	Current sense output	Analog voltage output proportional to load current (0.5 V/A) for real-time monitoring.
OUT	Half-bridge output	Drives motor terminal; connects between high-side and low-side MOSFETs.
VS2	Secondary supply pin	Provides additional decoupling path for internal gate drivers; ties to V_S externally.

Key Features

Feature	Design Value
Integrated high- and low-side MOSFETs	Eliminates need for external discrete half-bridge layout and gate-drive timing design.
Adaptive dead-time control	Prevents shoot-through by dynamically adjusting delay between high-side and low-side switching transitions.
Real-time current sensing	Enables precise torque control and stall detection without external shunt resistor or amplifier.
Comprehensive fault protection	Detects and reports overtemperature, overcurrent, open-load, and supply undervoltage conditions.

Applications

Power Seat Actuation

HVAC Damper Control

Use Scenario: Bidirectional movement of automotive power seat mechanisms under variable mechanical load.

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 current rating; identical pinout and protection features.	Preferred for higher-torque motors requiring >30 A continuous drive.	Select BTN7960B when thermal margin or peak load demands exceed BTN7930S capability.
VNH7040AS	STMicroelectronics device with 40 A peak rating, SPI diagnostic interface, and different pin assignment.	Supports advanced diagnostics via serial interface; not pin-compatible.	Choose VNH7040AS only when SPI-based fault logging and system-level integration are required.

Compared with BTN7960B and VNH7040AS, the BTN7930S offers optimal balance of current capability, thermal robustness, and analog diagnostic simplicity for cost-sensitive automotive body electronics where 30 A peak suffices and SPI is unnecessary.

FAQ

What is the maximum continuous output current rating for BTN7930S?

The BTN7930S supports up to 14 A continuous output current at T_A = 25 °C with adequate PCB copper area and heatsinking. This value decreases with rising ambient temperature and reduced thermal resistance-derating curves in the official Infineon datasheet define exact limits per board layout and airflow conditions.

Does BTN7930S require an external bootstrap capacitor?

No. BTN7930S uses an internal charge-pump circuit instead of a bootstrap capacitor to generate the gate voltage for the high-side MOSFET. This eliminates the need for external high-voltage capacitors and simplifies PCB layout while supporting 100% duty-cycle operation.

Can BTN7930S drive inductive loads other than DC motors?

Yes. BTN7930S is qualified for driving any inductive load within its voltage and current ratings, including solenoids, valves, and relays. Its integrated clamp diodes and overcurrent protection ensure safe commutation and fault handling for such loads.

How is the current sense output (IS pin) calibrated?

The IS pin provides a factory-trimmed 0.5 V/A analog output with ±5% gain tolerance across temperature and supply voltage. No external calibration is required; it connects directly to an ADC input for real-time current measurement, with offset error compensated in firmware if needed.
