The MAX14870ETC+T is a high-performance integrated motor control and protection IC designed to drive three-phase brushless DC (BLDC) motor applications with speed and current loop control. This motor driver has a wide field of application including Uninterruptible Power Supplies (UPSs), air conditioners, fans, electric tools, home appliances and vacuum cleaners.

The MAX14870ETC+T includes both motor control logic and a protection circuit which is optimized for BLDC motors. It simplifies the application design by integrating the most commonly used functions into a single IC. It includes a high-resistance bootstrap diode, a 3.2V linear regulator, a dead-time control circuit, overvoltage, overcurrent and short-circuit protection. It also contains an undervoltage lockout and overtemperature protection, as well as anti-cogging and motor control functions.

Its PWM input interface is designed to support both single-edged and complementary PWM inputs, with adjustable dead time for current output. It operates in continuous or quadrature modes, with current loops for selected motor types such as trapezoidal and sinusoidal. Its dc-bus undervoltage lockout function can be used to protect the motor from driving errors during operation.

The MAX14870ETC+T motor driver can be used to control a brushless DC motor by applying a low voltage gate drive voltage to the power MOSFETs. It has a built-in linear regulator and high-resistance bootstrap diode. This eliminates the need for an external regulator and bootstrap diode. The protection circuit includes both overvoltage and overcurrent protection, as well as short-circuit and overtemperature protection. It also includes a low-on resistance MOSFET current sensing circuit, which helps to detect short-circuits and overcurrent events.

The MAX14870ETC+T motor driver can be used in a wide variety of applications, including Uninterruptible Power Supplies (UPSs), air conditioners, fans, electric tool, home appliances and vacuum cleaners. It is an ideal solution for applications that require smooth torque, precise speed control, and increased efficiency.

In conclusion, the MAX14870ETC+T motor driver is designed to drive three-phase brushless DC motor applications with speed and current loop control. It integrates commonly used functions such as a high resistance bootstrap diode, a linear regulator and a dead-time control circuit, in addition to overvoltage, overcurrent and short-circuit protection. It also includes an undervoltage lockout and an overtemperature protection. It is suitable for a wide range of applications such as Uninterruptible Power Supplies (UPSs), air conditioners, fans, electric tools, home appliances and vacuum cleaners.
