MAX6714BUB+T is a 2kVrms transient voltage and current supervisor device designed for maintaining power supplies at regulated levels. It integrates a supervisor, temperature and over temperature protection, as well as a power switch. This power switch provides a buffered enable/disable function to control external P-channel and N-channel MOSFETs used in the application. This ensures low power dissipation when the MOSFETs are turned off.

The MAX6714BUB+T applies input voltages of +4.75V to +19V and provides protection for either an input current limit of +4.75A or an over-temperature limit of +150°C. The built-in over-temperature monitor keeps an eye on the external temperature and shuts down the power supply if it exceeds 150°C. The device also includes an input bypass pin that allows the device to take advantage of an interrupt-driven power-down mode. This pin discourages external circuitry from taking over the power-down process.

The MAX6714BUB+T supervisor is designed to work in conjunction with MOSFETs. The device provides potentiometer adjustment of startup delays, soft start, inductor current limit threshold, and MOSFET turn-off time. To further prevent the MOSFETs from turning on too quickly or too slowly, the MAX6714BUB+T includes an open-drain driver that allows an external pull-up resistor to speed up the MOSFET turn-ons. This pulse-width modulation (PWM) control increases efficiency by reducing the output voltage ripple.

The MAX6714BUB+T features a power-down mode in which the MOSFETs are turned off when the input voltage drops below a prescribed voltage, or when the temperature exceeds a predetermined limit. The device also includes an input bypass pin that allows it to take advantage of an interrupt-driven power-down mode, discouraging other external circuitry taking over the process. And the thermal protection circuit automatically shuts down the power supply when the temperature exceeds the limit set by the user.

The MAX6714BUB+T is ideal for a variety of applications where reliable supply voltage control is required, including motorsport applications, industrial automation, power systems, and embedded systems. It is capable of delivering fast current limit response, frequency control, and low-dropout performance. With its low on-resistance and its wide input voltage range, it is an ideal choice for cost-sensitive embedded systems.

The MAX6714BUB+T supervisor is the perfect solution for many applications that require reliable supply voltage control. It is designed to provide fast current limit response, frequency control, and low-dropout performance, making it the ideal choice for a variety of embedded systems. With its low on-resistance and its wide input voltage range, the MAX6714BUB+T will keep your system running smoothly and efficiently.
