MAX802LESA

Power Management IC (PMIC) devices are designed to regulate, monitor, and optimize power-related components in a variety of applications. Supervisors, one type of PMIC device, are an ideal solution for system high-level monitoring, protection, and reset, especially in portable or embedded systems. The MAX802LESA, a Low-Voltage, High-Current Reset/Power-On Reset (POR) voltage supervisor IC, is designed to provide excellent system resilience in battery-powered and other portable systems.

Application Field: The MAX802LESA is a low-voltage, high-current, active-low reset supervisor IC that monitors system power supply and issues a reset (active low) when VOH falls below the pre-programmed reset voltage threshold. It is ideal for use in a wide range of applications, from low-power to high-power embedded system designs. It features a very low quiescent current draw, enabling longer system uptime in battery-powered and other portable systems, making it an ideal choice for a wide range of applications, from communication and medical systems to automotive, test and measurement, and home entertainment.

Working Principle: The MAX802LESA has an active-low reset output that is set high at reset voltage and then reset (active-low) when the reset voltage drops below the pre-programmed reset threshold. The reset output is designed to be used in conjunction with a series of load switches and other power switching circuits to provide an effective reset solution in low-power and high-power designs. When the reset threshold is reached, all circuits in the system are reset and the power supply remains in a low-power state until the system power voltage rises again. The MAX802LESA will then reset the system, returning it to its normal operation.

The MAX802LESA is designed to provide an effective and economical reset solution in a wide variety of applications. It features an active-low reset output and low quiescent current draw, enabling it to remain active for relatively long periods of time. It also features a wide operating voltage range, allowing it to effectively reset systems operating from a variety of voltage sources. Additionally, the MAX802LESA has an hot-swap capacitor feature that allows the capacitor to remain charged even when the power is removed from the circuit, ensuring reset even in the event of an unexpected power interruption.

The MAX802LESA is an ideal solution for low-power, medium-power and high-power embedded system designs. It provides excellent system resilience in battery-powered and other portable systems, as well as provides an efficient and cost-effective reset solution in a variety of applications. Additionally, the MAX802LESA\'s active-low reset output and low quiescent current draw allows for relatively long system uptime in battery-powered or other portable systems, providing the ideal solution for a wide range of embedded system designs.
