TC647EOA

PMIC - Motor Drivers, Controllers

The TC647EOA is a motor driver, controller and PMIC device that is used to power DC and AC motors. It is engineered to be an efficient and reliable driver for various motor types, and is designed to reduce current consumption while providing superior performance.

The TC647EOA integrates several features that allow it to operate in a wide variety of applications. It includes a dual-mode control circuit with a digital current limitation, which provides a higher current limit than conventional drivers. It also contains a built-in gate driver with thermal protection and can provide a 50mV gate drive.

The TC647EOA also features a temperature monitor and an open-loop temperature control. This feature allows for the device to operate at optimum temperatures and at maximum efficiency. The device also features a current-sense transistor with a sense resistance of 0.25 Ohms and a wide operating temperature range of -40°C to +150°C.

The device has two adjustable current limits - one for motor phase current and one for motor B phase current. The motor current limit is adjustable up to 11A. The TC647EOA utilizes PWM inputs for commutation control and sensored transistors for torque production. The device can support motors with either three or four wire winding configuration.

The TC647EOA also includes a self-protection system, which guarantees a safe and reliable operation. The self-protection system includes a thermal shutdown that trips at a maximum chip temperature of ~?15C. The system also includes an under-voltage protective circuit that trips at 15V, an over-voltage protection circuit (200V) and an under-voltage protective circuit (2V).

The TC647EOA has become a popular choice for motor drive and PMIC applications. Due to its high current rating, wide operating temperature range, self-protection system and flexible interface, the device provides superior performance and reliability.
