Supervisors: MAX6338AUB Application Field and Working PrinciplePMIC or Power Management Integrated Circuit is a system-level solution for power control and efficient power conversion. Power-management integrated circuits (PMICs) are designed to provide optimum power efficiency, optimal reliability, and thermal performance. In today’s electronics industry, there is a need for improved efficiency and increased reliability in power delivery. This is particularly true in applications where the power supply is often exposed to harsh environments, such as the automotive industry.The MAX6338AUB by Maxim Integrated is a supervisor device developed to meet the requirements of automotive, industrial and consumer applications. It provides monitoring, protection, and control functions to maintain the integrity of the power system. The device provides undervoltage, overvoltage, and overcurrent protection to the system and supports a wide variety of power topologies as well as output capability such as PWM, and pulse-width modulation/dead time control (PWDTC).The MAX6338AUB is a three-channel device for monitoring voltage, undervoltage, overvoltage, and overcurrent. Each channel can be independently configured for various output capability such as PWM, or PWDTC. Utilizing the device’s programmable UVLO, SLP, and DLY registers, the MAX6338AUB can be configured for various power topologies such as flyback, boosted, and buck-boost.In addition, the MAX6338AUB is available in both SOT-23 and four SSOP packages and provides integrated diagnostics to help ensure correct operation of the power system. Integrated diagnostics include power-on reset (POR), undervoltage lockout (UVLO), run flag, and thermal shutdown (TSD). Other features include detection of overvoltages up to 30V, Temperature Operation up to 125°C and adjustable input bootstrap voltage of 5V, 8V, 9V, 10V, and 12V. The MAX6338AUB is ideal for applications such as automotive, industrial, and consumer power supplies, motors and actuators, battery monitoring systems and protection circuits. The device can provide a cost-effective solution for efficient system power management.The MAX6338AUB can provide efficient system management with its user-programmable undervoltage lockout (UVLO). This programmable parameter ensures the correct operation of the system by setting the voltage at which power is supplied to the load. With its overvoltage threshold, the device helps prevent any damaging overcurrent conditions by turning off the power when the predetermined voltage is reached. The adjustable input bootstrap voltage control of the device allows for optimal utilization of transient energy in the power supply and efficient power control for improved power efficiency. The MAX6338AUB provides a wide variety of protection and monitoring capabilities. With its overvoltage protection, the device monitors the output voltage of the power source and shuts down the system when it reaches a predetermined voltage limit. It also provides thermal shutdown protection to protect the system from any thermal damage. The device also offers protection from overcurrent conditions with both DLY (Delay) and SLP (Slew Rate Limiting) functions. Finally, the Run Flag feature of the device helps avoid incorrect behaviors of the power system. In conclusion, the Maxim Integrated MAX6338AUB supervisor device provides a user-friendly solution for efficient system power management. The device offers a variety of protection and monitoring functions, which allow the device to protect the system from damaging overcurrent conditions, monitor the output voltage of the power source, and prevent incorrect behaviors of the power system. The MAX6338AUB is ideal for applications such as automotive, industrial, and consumer power supplies, motors and actuators, battery monitoring systems, and protection circuits.
