T8082U is a monolithic bidirectional DC motor driver integrated circuit. It integrates brake circuit, surge absorption circuit and over temperature protection circuit. The device supports forward rotation, reverse rotation, braking and standby mode, with voltage adjustable speed function. It is widely used in small household appliances, audio and video equipment, intelligent toys and low-power DC motor drive scenarios.

Supports bidirectional motor drive and stable braking performance.Built-in surge absorption structure to suppress voltage spike generated during motor commutation and braking.Equipped with independent speed control pin, which can adjust motor speed by external control voltage.Logic input is compatible with CMOS level signal, convenient for single-chip microcomputer direct control.Built-in thermal shutdown protection function, automatically cut off output when the chip overheats to avoid damage.Low standby operating current, energy saving and high stability.Adopt SOP-8 package, easy for circuit board mounting and mass production.

Pin 1 is ground terminal.Pin 2 is motor output terminal 1.Pin 3 is speed control voltage input terminal.Pin 4 is logic control input 1 for forward and brake signal control.Pin 5 is logic control input 2 for reverse and brake signal control.Pin 6 is internal signal power supply terminal.Pin 7 is motor power supply terminal.Pin 8 is motor output terminal 2.

When both control input pins are low level, the motor enters braking state.When control input 1 is high level and control input 2 is low level, the motor runs forward.When control input 1 is low level and control input 2 is high level, the motor runs in reverse.When both control input pins are high level, the chip enters standby state and the motor stops working.

The maximum rated supply voltage of power supply and signal supply is 14V.Single channel maximum output drive current is 800mA.Normal operating temperature range is from minus 25 degrees Celsius to 75 degrees Celsius.Storage temperature range is from minus 55 degrees Celsius to 150 degrees Celsius.

Under standard test conditions, the typical standby current is 6.5mA.The output saturation voltage is low, which can reduce power loss during motor operation.The typical thermal protection shutdown temperature is 165 degrees Celsius.

Connect pin 7 motor power supply to 7V to 12V DC power supply.Connect pin 6 signal power supply to 5V standard DC voltage.Pin 1 is connected to system ground.Pin 2 and pin 8 are directly connected to both ends of the DC motor.Pin 3 accesses 0 to 5V adjustable voltage to realize motor speed regulation.Pin 4 and pin 5 are connected to MCU logic IO port to control forward, reverse and brake functions.

Used for tray motor drive of audio and video equipment.Various small DC motor forward and reverse drive with braking requirement.Intelligent toys, small household appliances and portable electronic equipment motor control circuit.

T8082U is packaged in SOP-8, with compact size and suitable for surface mount process.
