The MAX802LCSA is a voltage detector and supervisor integrated circuit manufactured by Maxim Integrated. This device is used to supervise the operation of circuits within the system that require a specific voltage input such as power supplies, clocks, or reference voltages. The MAX802LCSA is part of the Power Management Integrated Circuit (PMIC) Supervisors family, providing a wide range of features while consuming low current.The MAX802LCSA is an voltage detector used to monitor the status of multiple supply voltages in a single application. It is used to detect when voltages are out of a user-defined threshold, and to provide a status signal to the host system for appropriate action. The MAX802LCSA is a solution for applications with high power supply voltage accuracy requirements, as it can accurately detect up to ±1% of the threshold voltage. The MAX802LCSA has a low quiescent current of 1.5µA, allowing it to operate in low power environments. It also has an adjustable threshold voltage from 2.5V to 5.8V and adjustable hysteresis which can improve the accuracy of the voltage detection by reducing the noise immunity of the output signal. The device also features an open-drain reset output that is active-low, which is asserted when the input voltage drops below the user-defined threshold. This reset output can be used to trigger interrupts and/or reset other ICs that are part of the system.The MAX802LCSA also provides excellent EMC and ESD protection, ensuring reliable operation in harsh environments. The device features a protection circuit that limits the voltage at the output to 28V, which helps protect against overvoltage and electrostatic discharge (ESD). The MAX802LCSA also features an on-chip ESD protection diode, which helps protect the device from both lightning strike and ESD transient events.In summary, the MAX802LCSA is a great choice for applications where the power supply voltage accuracy is critical. With its low current operation and superior protection against overvoltage and transient events, the MAX802LCSA is an ideal supervisor for low-power and accurate voltage-detection applications.
