Tle6285Gduma1 is an integrated power stage bridge-mode driver IC from Infineon. It is designed for driving three-phase brushless AC fans and DC motors. It operates from 5.5V to 36V supply voltage and provides output currents up to 3.2A. It features programmable frequency, over temperature protection and over/under-voltage protection.

The device is applicable for 3-phase brushless AC fans and DC motors with 5.5V to 36V supply voltage. It supports programmable frequency up to 32MHz for PWM control of fan or motor speed adjustment by controlling PWM duty cycle. The device offers over temperature protection and under/over-voltage protection of the power stage device to ensure the fan or motor operates correctly and reliably.

Working principle:

Tle6285Gduma1 works by controlling the flow of current within the device. It provides gate pulses to the upper and lower power MOSFETs and it works in bridge mode where two switches are connected at the two ends of the motor and the other two at the other two ends of the motor. It controls the direction of current flow by turning the two switches on or off depending on the input signal. Therefore, it can be used for applications like variable speed control, speed reversal and power factor correction.

The device is used in a wide range of applications such as industrial machines, HVAC systems, medical devices and robotic systems. It can operate in conditions ranging from -40°C to 125°C and can withstand high supply voltages in order to drive motors with higher power requirements. The device also offers high current capability and protection against short circuits, ensuring reliable operation.
