TC1410NCPA Application Field and Working Principle

PMIC - Gate Drivers

The TC1410NCPA is a high-performance gate driver produced by Texas Instruments (TI). It is typically used for driving small N-channel or P-channel MOSFET and IGBTs in various power and industrial applications ranging from motors to power converters, PFC, and more. The device is a monolithic integrated circuit featuring a low-voltage, low-power, high-speed driver with an integrated sense FET and isolated pulse current limit.

TC1410NCPA consists of a differential input stage, a low-voltage-translation stage, a precision voltage reference and a driver core. The differential input stage is used to process the remote voltage sensed from the upper power switch, providing a differential difference between the two voltages. This differential difference is then used by the low-voltage-translation stage to convert the voltage to an appropriate level to process by the rest of the device, allowing for proper operation.

The TC1410NCPA features a precision voltage reference, which is used to accurately set low voltage level, providing a corresponding reference voltage while reducing the quiescent current of the smart gate driver, ECU and MCU. The TC1410NCPA also features a driver core, which is used to drive levels up to 500mA. The low power, fast switching speed, and high output current capability of this section make it suitable for a wide range of applications, from motor control to industrial applications.

The TC1410NCPA also integrates a sense FET. This allows for the device to sense and adjust the voltage across the hot side of the switch open circuit (e.g., a MOSFET). The sense FET is also used for PWM current limit termination. The integrated isolated pulse current limit helps limit the maximum current of the smart gate driver as well as the power switches.

In summary, the TC1410NCPA from Texas Instruments is an integrated, high-performance gate driver. The TC1410NCPA features low-voltage, low-power, high-speed operation with an integrated sense FET and isolated pulse current limit. These features make it ideal for a variety of power and industrial applications ranging from motors to power converters, PFC, and more.
