The AH9282RTR-G1 is a motor driver, controller and power management integrated circuit (PMIC) released by Advanced Motor Control (AMC) in August 2020. The AH9282RTR-G1 helps customers simplify power management design and achieve efficient motor control in a wide range of applications.

Designed for high performance and power efficiency, the AH9282RTR-G1 is a monolithic, ultra-low quiescent current integrated circuit (IC). The dual channel half-bridge motor driver includes two independent high-side/low-side outputs, each with internal protection features. With on-chip protection features such as short circuit protection, over-current protection and under-voltage protection, the AH9282RTR-G1 provides a high level of reliability.

In addition, the AH9282RTR-G1 utilizes Enhanced Spread Spectrum Control (ESSC) to reduce electromagnetic interference (EMI) without compromising performance. This technology reduces peak current and peak voltage by spreading the frequency of the current waveform and reducing the energy in the high-frequency harmonics without affecting the overall performance. This allows for a more robust design and also reduces the levels of radiated and conducted EMI.

The AH9282RTR-G1 is designed for a wide range of applications such as automotive, household appliances, and industrial applications. It can be used in motor control systems such as brushless DC (BLDC) motor control, wind turbines, industrial robots, and renewable energy systems. The AH9282RTR-G1 can also be used to control stepper motors, voice coil motors, and brushless servo motors, as well as many other motors and applications.

The AH9282RTR-G1 is based on AMC\'s lightningstrike motor control architecture and includes a range of features to meet the needs of a variety of applications. The motor driver features internal protection features, such as short-circuit, over-current and under-voltage protection. The device can also be customized for different applications, with the ability to adjust PWM frequency, clock frequency, pulse-width modulated (PWM) duty cycle, and dead time.

The AH9282RTR-G1 is designed to offer a wide operating range from 4.5V to 78V and a maximum output current of 14A. It also offers a low on-resistance of just 10mΩ at 25°C and a high switching frequency of up to 1.5MHz. The high switching frequency reduces power consumption by reducing switching losses, while the low on-resistance ensures efficient and accurate motor control.

As a motor driver, the AH9282RTR-G1 is a powerful, versatile and reliable PMIC. It is suitable for a variety of applications and its features ensure efficient and accurate motor control. With its on-chip protection features, it also provides reliable operation in harsh environments. AMC\'s lightningstrike motor control architecture also helps to reduce EMI, making the AH9282RTR-G1 a suitable solution for applications that require high performance, power saving, and reliability.
