Power management isolated circuit (PMIC) is a special type of integrated circuit (IC) designed to operate in an isolated environment or in a high voltage environment with a voltage range of 10 V - 65 V. PMICs are commonly used in motor control, power conversion, and system-level DC/DC power management. The UCC27423DRG4 is a dual-channel gate driver that is widely used in motor control and power conversion applications.

The UCC27423DRG4 is a dual-channel, low-side, linear-mode power switch with built-in protection and drive capability. It is designed to drive a pair of external N-Channel MOSFETs and can be used in a variety of applications, from switching to inrush. The product includes an overcurrent protection (OCP), short-circuit protection (SCP), and thermally monitored input and output current limits for over-current protection.

The UCC27423DRG4E4 can drive up to two N-channel external MOSFETs in low-side switch configurations. It features an internal 5 A current-limited linear drive, overcurrent protection (OCP), short-circuit protection (SCP), and an integrated charge pump for eliminating the need of an external gate drive supply. The built-in gate drive and protection make the UCC27423DRG4E4 an ideal solution for a wide range of low-side switch applications, such as motor control, power management and power conversion.

The UCC27423DRG4E4 is designed to operate over an input voltage range of 10 V - 65 V and has an operating temperature range of -40°C to +125°C. The IC also supports an adjustable overcurrent level and adjustable over temperature shut down. The device is highly integrated and requires only a few external components, and it is also EMC compliant, meaning it is resistant to noise from external sources such as EMI and ESD.

The UCC27423DRG4E4 utilizes a proprietary high speed self-oscillating gate drive to deliver fast switching performance and robust EMI protection. The device is also capable of delivering up to 25 A per channel of steady-state current and 45 A peak current. The built-in charge pump further boosts the operating frequency, allowing for faster gate risetimes, increased system efficiency, and improved EMI performance.

The UCC27423DRG4E4 provides a robust, reliable and cost-effective solution that meets the needs of a wide range of low-side switch applications such as motor control, power conversion and power management. The product can be used to switch a wide range of loads, from small DC motors to high-powered AC motors. The device’s built-in protection and gate drive enable it to be used in high temperature and harsh industrial applications, making it an ideal solution for any low side switch application.
