NCV5701BDR2G is a high efficiency gate drive manufactured by ON Semiconductor and is designed for driving a bridge of Gate Voltage (VGS) in power switching applications as a part of a power management integrated circuit (PMIC). The device provides excellent performance, efficient and reliable gate drive power with minimum system cost.

Overview

NCV5701BDR2G PMIC Gate Driver is the ideal choice for driving a bridge of Gate Voltage (VGS) in power switching applications. It features a dedicated high and low side signal channel in each driver, which is released and then clamped with a series resettable over-temperature protection for each respective driver. The device also features an Under Voltage Lockout (UVLO) with hysteresis, Under Voltage Protection (UVP), Over Temperature Protection (OTP) and an enable/disable control circuit. It is rated for an input voltage range of 10V to 36V, and delivers up to 1A of peak current to each of the two drivers.

Features and Benefits

High Efficiency: NCV5701BDR2G PMIC Gate Driver is the highest efficiency gate driver PTMIC, providing an impressive 94% efficiency which reduces power dissipation, while allowing extremely lower power losses.

Maximum System Cost Savings: The device features a low quiescent current, which also reduces the overall power dissipation, resulting in a lower bill of materials cost, and lower total system costs.

Printed Circuit Board Area Reduction: The NCV5701BDR2G maintains very high efficiency over a wide input voltage range, while allowing design flexibility and minimal printed circuit board area.

High Power Protection: The device includes integrated gate drive protection, over-temperature protection and Under Voltage Lockout (UVLO), making it well suited for high-power applications.

Applications

The NCV5701BDR2G PMIC Gate Driver is suitable for a variety of applications including motor controllers, power converters, welding equipment, automotive battery chargers, AC/DC converters, switching regulators, DC/DC converters and motor drive circuits. It can also be employed in other gate drives, such as for microprocessor power management, electric heating and air conditioners.

Working Principle

The NCV5701BDR2G PMIC Gate Driver includes two independent gate drivers, each with a dedicated high and low side signal channel. The driver has an internal clamp which releases when an over-temperature condition is present. This results in a series resettable over-temperature protection for each respective driver. When the device is enabled, signals on each of the two drivers are turned on with a controlled slew rate to protect against inductive spikes.

The device also features Under Voltage Lockout (UVLO) with hysteresis to protect against input supply under-voltage conditions, as well as Under Voltage Protection (UVP) to prevent unbalanced outputs at low input voltages. The NCV5701BDR2G also features integrated over-temperature protection to ensure safe operation, and an enable/disable control circuit to enable or disable the two drivers.

Conclusion

NCV5701BDR2G PMIC Gate Driver is an ideal choice for driving a bridge of Gate Voltage (VGS) in power switching applications. Its high efficiency and integrated fault protection enable maximum system cost savings and improved performance. Its wide input voltage range provides flexibility and board area reductions, making it well suited for various types of applications.
