The UCD3138RHAT is a high performance integrated PMIC (power supply controller, monitor) designed for use in industrial and automotive applications. It combines high-performance current sensing, power management, and power control functions into a single device. The device has a wide input voltage range (8-36V) and provides multiple output voltages, including adjustable output voltage, a programmable linear regulator, and pulse-width modulation (PWM). It is capable of driving an external MOSFET to provide up to 50A sink-mode current.

The device is based on an integrated single-chip current monitoring system which allows users to accurately monitor and control the current in their system. The system can be programmed to detect over-current, under-current, and over/under temperature conditions, and can provide feedback or corrective action to prevent any of these conditions from occurring. The UCD3138RHAT also offers a number of advanced power control features including programmable voltage and frequency regulation, adaptive load balancing and tracking, and over-current protection.

The UCD3138RHAT is optimized for use in high-temperature applications such as automotive, industrial, and medical applications. It is designed to operate over a wide temperature range (-40C to +105C), and provide higher reliability than traditional discrete components. The device has a low quiescent current of just 2.1mA, making it suitable for applications with battery-powered supply.

The UCD3138RHAT utilizes a single 2.7V to 18V voltage input to provide up to 4.5A of load-dependent output current. The device also features a built-in temperature and current sensing system, allowing for accurate control over output current and voltage. An enable and reference voltage pins allows for easy on/off power control and scalability.

The device offers a wide range of adjustable output functions including programmable linear regulators, pulse-width modulation (PWM), multi-phase AC/DC, and a bias controller. It is also compatible with multiple popular communication protocols such as I2C, JTAG, SPI, SMBus, and UART. The device is also capable of driving a MOSFET to support up to 50A of sink-mode current.

The UCD3138RHAT is a versatile PMIC (power supply controller, monitor) designed specifically for use in industrial and automotive applications. It is capable of highly accurate current sensing and power management and control functions, and its wide input voltage range (8-36V) and built-in protection make it well-suited for a variety of high-temperature and load-dependent applications. Its low quiescent current and extensive communication protocol support make it the ideal choice for system integrators seeking to quickly and accurately implement a reliable power solution.
