BTN8982TA Product Brief

Product Brief
NovalithIC™ BTN8982TA
Integrated high current half-bridge motor drivers
The BTN8982TA is an integrated high current half-bridge for motor drive applications. It
is part of the NovalithIC™ family containing one p-channel high-side MOSFET and one
n-channel low-side MOSFET with an integrated driver IC in one package.
Due to the p-channel high-side switch the need for a charge pump is eliminated thus
minimizing EMI.
Interfacing to a microcontroller is made easy by the integrated driver IC which features
logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, undervoltage, overcurrent and short
circuit.
The BTN8982TA provides a cost optimized solution for protected high current PWM motor
drives with very low board space consumption.
Key benefits
››Easy to use and fast design-in – driver, FETs, load current sensing and diagnostic and
protection functions – all integrated in one package, promoting fast and lean design-in
activities
››Full flexibility – the BTN8982TA supports BDC motors in half- or H-bridge configuration
as well as BLDC motors
››Cost optimized through system level savings – compared to a discrete solution,
the BTN8982TA saves PCB-area and pick and place costs. Furthermore it requires less
passives due to its integrated diagnosis and protection functions.
››Functional safety – the BTN8982TA includes an integrated under voltage, MOSFETs’
overtemperature- and overcurrent protection, measured directly in the MOSFETs. In an
H-bridge configuration, the BTN8982TA furthermore provides a redundancy case for
functional safety.
››Configuration flexibility – settable switching speed for optimized EMI vs. power
dissipation
