Product details

BLDC commutation controller with integrated pre-driver

The TC78B006FNG,EL is a brushless DC (BLDC) motor controller that integrates commutation logic and a pre-driver stage. It accepts a 3.5V to 16V supply rail and outputs two half-bridge drive signals, making it suited for small- to medium-power BLDC motors in fan, pump, or spindle applications where the external power stage handles the high-current switching. The controller uses a PWM interface for speed and direction commands, and the internal Power MOSFET technology drives the external half-bridge FETs.

Package and supply integration

The 3.5V to 16V supply range means a single 12V or 5V rail can power the controller directly, simplifying the power tree. The half-bridge outputs are pre-driver level — an external FET bridge handles the motor current, so the controller's own dissipation stays low even at higher bus voltages.

Frequently asked questions

What is the difference between TC78B006FNG,EL and TC78B006FTG,EL?

Both are BLDC pre-drivers with identical function (Controller - Commutation, Direction Management), output configuration (Pre-Driver - Half Bridge (2)), interface (PWM), supply voltage (3.5V), motor type (BLDC), and temperature range (-40°C to 105°C). The difference is the package: TC78B006FNG,EL comes in a 16-LSSOP (4.40 mm width) while TC78B006FTG,EL uses a different package variant. They are not pin-compatible without a board layout change.
