Power management integrated circuits (PMICs) are a type of integrated circuit designed to manage the power of digital circuitry. Among its different types, Supervisors are a vital component used to ensure the safety of the power supply within a system. The DS1830A+ is a high-speed dual MOSFET driver and system supervisor IC from Maxim Integrated that facilitates fault protection and power sequencing control for ADAS, Autonomous and HEV applications.

The Maxim Integrated DS1830A+ is a smart, advanced circuit protection solution for the aggressive current margining needs faced by designers of Level 4 Autonomous, Hybrid Electric Vehicle (HEV), and Advanced Driver Assistance Systems (ADAS) systems. Not only does it provide a high-power drive and enhanced protection to power trees, but it also offers a wide range of programmable features to enable overcurrent, voltage and temperature protection. Moreover, the DS1830A+ offers increased safety by providing an active system supervisor that monitors multiple rails and logical input signals to ensure safe conditions for system power-up and power-down.

Application Field

The Maxim Integrated DS1830A+ is optimized for automotive and industrial applications, with features that can be used for time-critical power sequencing as well as fault protection. The features of this chip are such that it can easily be adapted to either an automotive system or an industrial system, providing versatile protection to the power supply. In automotive applications, the DS1830A+ can be used to control the voltage and current supplied to the drivetrain, brakes, and other crucial components, while in industrial applications it can provide protection and monitoring of systems such as communication networks, medical equipment, and machine automation.

Working Principle

The DS1830A+ is designed to ensure the safe operation of the system by actively monitoring the voltage, current, and temperature of the system. It can also monitor the logical input signals to ensure that the system is in a safe, powered-up state. In addition, the DS1830A+ has a built-in programmable timer, allowing for precise time management for power-up and power-down operations.

The DS1830A+ incorporates a dual MOSFET driver, which is capable of delivering 15A at 55V. This section of the chip is used to control and switch the power supply to various components of the system. This dual driver operates in conjunction with the supervisor section to ensure system safety and robust power supply control.

For improved system performance, the DS1830A+ provides adjustable blanking, allowing for the reduction of overshoot during the power sequencing process. This feature can be used to reduce unnecessary power disturbances during high-current events.

The DS1830A+ also incorporates precision and wide-input voltage and temperature monitoring, as well as inrush current management to ensure the safety and robust operation of the system. Additionally, the chip includes a reset timer, allowing for system restart if a fault condition is detected.

The DS1830A+ provides a reliable and versatile solution for system power management, allowing designers to use one single chip instead of the complex and costly power conditioning circuits. It is ideal for applications that require robust system protection and power sequencing.
