MAX6389XS16D3+T

MAX6389XS16D3+T is an integrated power management IC (PMIC) with a supervisor built to operate at temperatures up to +150°C. It supplies three low-dropout (LDO) regulators, a supervisor and two push-button power switch outputs, making it an ideal solution for high-temperature/harsh-environment applications.

Features

The MAX6389XS16D3+T integrated power management IC provides four output channels on a single die: three low-dropout (LDO) regulators, a supervisor and two push-button power switch outputs. Its low operating voltage and power consumption make it a suitable solution for battery-powered and portable applications. Its high temperature range and array of features found in the supervisor make it an ideal choice for applications in harsh environments. The regulator’s wide input/output range and tight-load and line-regulation performance are suitable for powering general-purpose load current applications.

Application Fields

The MAX6389XS16D3+T is a highly integrated power management IC that integrates three low-dropout (LDO) regulators, a supervisor, and two push-button power switch outputs in a single package. Its low operating voltage and power consumption make it suitable for battery-powered portable applications. Its applications best suited for harsh environments, like automotive, industrial and telecommunications applications. The small package size of it allows it to fit small space, like portable, handheld devices. Its wide input/output range and tight-load and line-regulation performance makes it an ideal choice for powering general-purpose load current applications.

Working Principle

The MAX6389XS16D3+T works by combining three LDO regulators, a supervisor and two push-button power switch outputs on one die. The LDO regulators provide a regulated output voltage between 0.8V and 9V, and have a typical output current of up to 2A. The supervisor has a watchdog timer and reset generator that provides essential protection against power loss or voltage fluctuations. It can also be used to detect inputs coming from the push-button power switch outputs. The two push-button power switches have up to 25mA current-source load currents and standby currents, which are automatically disconnected when the power switch is not selected.

The system can be reset either with the supervisor or with a manual reset input. The supervisor can provide a reset signal to the system for several reasons. This can help protect itself from conditions such as overvoltage, undervoltage, overcurrent, brownout, or excessive die temperature. All of these protections help ensure that the system is kept running at a stable voltage and current.

The MAX6389XS16D3+T comes with numerous protection features, such as overcurrent, overvoltage, undervoltage, short-circuit, thermal, and other protection features. These protect the system from a variety of potential malfunction scenarios. Its wide input/output range and tight-load and line-regulation performance make it perfect for powering general-purpose load-current applications.
