TLE7188F 3-Phase Bridge Driver IC – High-Current Gate Driver for EPS & Steering Control Modules
The TLE7188F is a dedicated three-phase bridge driver IC engineered specifically for automotive motor control applications requiring high current handling capability.
This powerful gate driver is designed to control six to twelve external N-channel power MOSFETs forming the converter for high-current three-phase motor drives in the automotive sector.
It is ideally suited for demanding systems including electric power steering, cooling fans, water pumps, and electro-hydraulic applications.
The device features three high-side and three low-side output stages, each powerful enough to drive MOSFETs with 400nC gate charge with rise and fall times of approximately 150 ns.
Supporting a wide supply voltage range of 5.5V to 28V, this driver is fully compatible with 12V automotive electrical systems.
An integrated charge pump principle allows all six output stages to be switched at PWM frequencies up to 25kHz.
Comprehensive protection features include shoot-through protection with integrated minimum dead time, short circuit protection with fixed detection level, and thermal overload warning for the driver IC.
Integrated over-current warning and detailed diagnosis capabilities provide real-time system monitoring for enhanced reliability.
The device incorporates three fast and precise operational amplifiers for conditioning and amplification of shunt signals, enabling accurate phase current measurements.
A disable function and sleep mode minimize power consumption when the system is idle.
Qualified to AEC automotive-grade standards, this IC delivers reliable performance across a wide junction temperature range of -40°C to 150°C.
Packaged in a compact VQFN-48 with exposed heat slug, it is designed for surface mount assembly in space-constrained PCB layouts.
For engineers developing advanced steering and motor control systems, this driver offers the power, protection, and precision required for modern automotive electronics.
