Infineon Technologies BTN7960BAUMA1

Overview

BTN7960BAUMA1 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 overcurrent protection. It is used in power seat actuators, HVAC blower control, and electric power steering auxiliary modules.

For engineers reviewing the BTN7960BAUMA1 datasheet, BTN7960BAUMA1 pinout, BTN7960BAUMA1 application, or BTN7960BAUMA1 equivalent, key selection criteria include peak current capability, integrated current sensing accuracy, thermal performance under sustained load, and diagnostic flag behavior during fault conditions.

Technical Context

The BTN7960BAUMA1 integrates two N-channel MOSFETs in a half-bridge configuration with matched on-resistance (R_DS(on) = 12 mΩ typical per channel) and fast switching transitions (t_rise/t_fall ≈ 100 ns). It uses internal logic to prevent shoot-through and supports PWM input frequencies up to 25 kHz.

Its integrated current-sense amplifier provides a buffered analog output proportional to load current (0.5 V/A), referenced to GND, with ±5% gain tolerance and <1% offset error at 25°C. Fault reporting is via open-drain INH output that asserts low on overtemperature or overcurrent events.

FAQ

What is the maximum allowable PCB copper area for thermal management of BTN7960BAUMA1?

Infineon specifies ≥400 mm² of 2-oz copper on the top layer connected to the exposed drain pad for 43 A continuous operation at 25°C ambient. Reducing copper area below 300 mm² requires derating to ≤30 A to maintain T_j < 150°C. Thermal vias (≥12×0.3 mm) to inner ground planes are mandatory for sustained loads.

Does BTN7960BAUMA1 support bidirectional motor control?

No - BTN7960BAUMA1 is a single half-bridge driver and only controls one motor terminal. Bidirectional operation requires two units in an H-bridge configuration (one per side) with complementary IN/EN logic to prevent shoot-through. The device itself does not integrate full H-bridge logic or cross-conduction protection between channels.

How is the current sense output (CS) calibrated across temperature?

The CS output has ±5% gain tolerance over -40°C to +150°C and <1% offset error at 25°C. No factory calibration is required; however, system-level offset correction at room temperature improves accuracy to ±2% across full temperature range. Gain drift is specified at ±100 ppm/K in the datasheet.

Can BTN7960BAUMA1 be used without the EN pin connected?

No - EN must be actively driven high (≥2.0 V) for normal operation. Leaving EN floating risks undefined behavior due to internal pull-down weakness; it may intermittently disable the device or cause erratic switching. A 10 kΩ pull-up to V_S is recommended if EN is controlled solely by MCU GPIO.
