TC1413COA is a gate driver PWM control IC created by Microchip Technology, Inc. It is considered a PMIC - Gate Drivers device, as it features precise, independent 2-channel output control with high-speed PWM control circuitry. It also integrates high side and low side driver circuits, as well as a linear regulator, all of which are held within a 12-lead TSSOP package. The TC1413COA is designed to provide precise, low-power control for a variety of high-current, high frequency motor applications. It is also capable of providing protection from high voltage and current transients, as well as under-voltage and over-current conditions.

The TC1413COA is commonly used in power-efficient brushless DC motors, solenoid coils and stepper motors, where a precise control signal is necessary. This is because it is capable of controlling up to 2½ A (1 A per channel) of output current, with a minimal power dissipation of less than 75 mW in an 8-bit PWM mode. Additionally, the device can be configured to provide a range of different frequency responses from as low as 1 kHz to 5 MHz.

The TC1413COA incorporates a high-efficiency linear regulator, which offers superior voltage regulation, ripple rejection and operation at low voltage levels. It can be used to generate any required operating voltage, within a wide input range of 5.5 V up to 18 V. Furthermore, this device offers a number of protective features, including input over-voltage protection, output over-current protection, output voltage tracking and fault current limit protection.

The TC1413COA’s circuit architecture is based around a high-gain PWM amplifier, which is powered by two 12-bit up/down counters. The two channels of this PWM amplifier are programmed independently, which enables a wide range of pulse and duty cycle control, while still providing low power consumption. The amplifier is connected to an output driver that is capable of providing up to 2½ A of output current. This is combined with buffers and protection circuits, allowing symmetrical current flow in one or both directions.

The TC1413COA also features several configurable options, which can be used to tailor its performance for specific applications. These include configurable frequency response ranges, adjustable PWM duty cycle range, and programmable dead time and drift compensation, as well as programmable thermal protection. All of these options can be adjusted via the onboard SPI port.

Overall, the TC1413COA is designed to provide precise and efficient motor control, with low-power consumption, wide input voltage and PWM frequency ranges and a high current output. Its onboard linear regulator, protective features and configurable options make it suitable for a wide range of demanding motor applications.
