The NCV7701DW is a cost-efficient, triple motor driver, controller, and power management system. The NCV7701DW is targeted at cost-sensitive motor driver, controller, and power management applications. It has three independent, low-side and high-side low-side drive outputs and a single power stage driver. The device operates from an input voltage range of 4 V to 45 V and is characterized for operation from -40°C to 125°C.

The NCV7701DW integrates several features that simplify system design and reduce the total system cost. It has an integrated sense and protection circuit that can monitor current, voltage, temperature, and other parameters to detect over-current or over-temperature conditions and shut down the system. It also has a wide range of integrated features such as PWM and timers, advanced power protection, fault reporting, and robust protection circuitry.

The NCV7701DW has three built-in, 3-phase dual-mode motor drivers which allow it to directly drive three unipolar stepper motors or up to six brushless DC (BLDC) motors. It supports both step and direction control modes and can directly drive the motor up to 48V. The device also provides an integrated speed control module which can provide PWM signal for speed control.

The NCV7701DW provides an additional protection level for system and embedded device protection against ESD, voltage spikes, and shorts. The low-side FETs are protected by over-current monitoring, under-voltage lockout, and adjustable current and voltage sense trip points. The high-side FETs are also protected by over-temperature and under-voltage lockout.

The NCV7701DW offers a wide range of protection options, such as power-on reset, watchdog timer, ESD protection, short circuit protection, and over temperature protection. The NCV7701DW is compatible with several standard interfaces and provides a wide range of communication protocols, including I2C, SPI, UART, and CAN.

The NCV7701DW is ideal for powering small, low-power motors in applications such as consumer electronics, industrial, home appliances, and robotics. The device is optimized for use in automotive and commercial applications and is also suitable for applications with high temperatures or limited space.
