The MAX1649ESA is a voltage rail thermal and load-current monitor and overload protection integrated circuit (IC), which is part of the various device families of peripheral management integrated circuits (PMICs). It is part of the Voltage Regulators section of PMICs, more specifically, the DC DC Switching Controllers. It is designed for use in voltage regulation and controlling applications, typically in low-noise and high-current-density environments, such as notebook PCs, and portable electronics.
The device includes sensing capability to monitor temperature and load current, in addition to other monitoring information. Its main function is to help protect against damage due to overloads, excess current draw, and excessive temperatures, creating a secure and reliable system environment. It also provides power monitoring and overvoltage/undervoltage protection.
The MAX1649ESA has two main sections, the current sense and the overcurrent protection (OCP) sections. The current sense section is used to measure the load current and temperature, and to provide power-fail/power-good indication. The OCP section is used to turn off the output if the load current or other parameters become too high, limiting any potential damages.
The main features of the MAX1649ESA include an adjustable OCP threshold current level, adjustable soft start time, adjustable throttle time, adjustable overvoltage protection (OVP) threshold voltage, and an adjustable undervoltage protection (UVP) threshold voltage.The OCP threshold current is adjustable to help prevent excessive current draw and short-circuit conditions. The soft start time is adjustable to help prevent inrush currents upon startup, or when the system is cycling. The throttle time is adjustable to decide how long the IC should remain in the disabled state. The OVP and UVP thresholds help protect against any overvoltage or undervoltage conditions.
The MAX1649ESA also features built-in voltage and temperature monitoring, to allow for additional safety features. It contains an analog-to-digital converter (ADC) to sample voltage and temperature levels. The device also includes an analog output for monitoring, and a sleep-mode pin that can be used to switch the device off when not in use.
The MAX1649ESA is a highly reliable device and is designed for use in a variety of industrial applications. It is designed to operate in both the automotive and industrial industrial operating temperature ranges, with its operating voltage of 2.5V to 45V. It is also designed to be protected against electrostatic discharge (ESD), electro-static discharges (ESDs), and other forms of electrical overstress.
The MAX1649ESA is a very useful device in voltage regulation and control, and is a perfect fit for notebook computers and other low-noise and high-current-density environments. It provides over-current and over-voltage protection, as well as temperature and load-current monitoring. Its adjustable features allow for an optimized system environment.
