NCV7513FTG Application Field and Working Principle

The NCV7513FTG is an integrated low-voltage, low-current, low-power PMIC (Power Management IC) motor driver, controller and regulator designed to control the operation of three-phase brush-type DC motors. It is designed to operate at voltages ranging from 16V to 18V, and outputs currents up to 15 Amps.

In addition to providing motor control, the NCV7513FTG also provides signals for other functions such as monitoring system temperatures and faults, as well as providing feedback to the main processing unit to ensure regulated power consumption. It also features adjustable slop compensation and current-limiting features to improve system reliability.

The primary application of the NCV7513FTG is to provide reliable, accurate, and efficient three-phase brush-DC motor control at low voltage and current levels. It is designed to be used in motor control applications such as Electronics Speed Controllers (ESC), Electric Speed Drivers (ESDs), voice coils, small industrial motors, HVAC systems, rotating actuators, and medical equipment.

The NCV7513FTG includes multiple integrated features which are important for motor control applications. These include:

• Low-Voltage and Low-Current Operation
• Adjustable Current Limit
• Dynamic Braking Capability
• Three-Level Motor Current and Voltage Monitoring
• Automatic Error-Reporting
• Integrated Multichannel PWM Control
• Built-In Overload Protection

The NCV7513FTG is a digital 3-level gate drive integrated circuit. It uses a standard 3-phase bridge configuration with N-channel MOSFETs as the power switches. The internal logic of the NCV7513FTG allows it to operate in two distinct operating modes: low-voltage startup and normal operation. During low-voltage startup, the device turns on all three-phase FET switches and then gradually increases the motor voltage to reach the programmed normal operating conditions. The device can be programmed to operate at voltages from 16V up to 18V.

In normal operation mode, the NCV7513FTG provides three-level motor control, enabling accurate and efficient control at low current levels. The motor current is monitored and can be adjusted, as needed, to achieve optimum performance. Additionally, the device includes integrated protections to prevent hard faults in the system, such as current limiting, over-current monitoring and dynamic braking. Finally, the device features automatic error reporting and multiple channels of integrated Pulse Width Modulation (PWM) control.

The NCV7513FTG is an ideal solution for low-voltage, low-current brush-DC motor applications, including Electronics Speed Controllers (ESC), Electric Speed Drivers (ESDs), voice coils, small industrial motors, HVAC systems, rotating actuators, and medical equipment.
