PMIC - Supervisors: MAX6388XS19D5-T Application Field and Working Principle

PMIC (power management integrated circuit) supervisors are integrated circuits that provide a set of functions to manage the power supply of a system. PMIC supervisors typically provide reset functions, power-on reset, voltage and over-temperature monitoring, as well as integrated level shifting and interfacing to standard system buses. The MAX6388XS19D5-T is a PMIC supervisor designed for applications such as desktop and notebook PCs, servers, network equipment, and single-board computers.

The MAX6388XS19D5-T features a variety of options for reset timing, including adjustable power-on reset (POR) delays, reset width and reset active-low or active-high assertions. The device also includes a power-on reset (POR) adapter which allows the POR time to be adjusted to any value between 15 ms and 4 sec. Additional features include a power fail detection circuit and an integrated voltage monitor.

The MAX6388XS19D5-T supervises the power supply in a system by monitoring the power-on reset (POR) and/or voltage levels of the system. The supervisor provides a reset output that is asserted whenever the main power supply drops below a predetermined voltage level. This reset output allows the system to identify and respond to power supply fault conditions before the processor is affected. Additionally, the device provides an integrated voltage monitor for monitoring voltage levels during system startup and operation, and can be used to detect over-voltage conditions.

The device can be configured with a variety of reset assertion options to control the behavior of the reset output. These options allow the system to be configured to ensure that the reset output is asserted when a power supply fault is detected and that the reset is not asserted if the fault condition is corrected. Additionally, the device includes an integrated level shifter that translates logic levels between the processor’s supply rail and the device’s power supply.

The integrated voltage monitor of the MAX6388XS19D5-T is used to provide a warning when the system power supply is over-voltage or under-voltage. If an over-voltage condition is detected, the voltage monitor can be configured to assert a reset output to prevent the system from entering an unstable state. The MAX6388XS19D5-T is designed to operate over a wide range of input voltages from 2.5V up to 5.5V.

The MAX6388XS19D5-T is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) allowing for easy mounting on a variety of boards. It features a very low power consumption of only 10µA (ma) at 3V and a very low static power consumption of only 5µA at 3V. The device also includes a 40µA Brown-out Reset that is set at 1.7V to keep the processor in reset when the voltage drops below the specified threshold.

The MAX6388XS19D5-T provides a variety of options for reset timing and voltage monitoring to enable more precise power-down control in portable and embedded systems. It provides a reliable means of monitoring the voltage of the power supply, as well as a reset signal that can be used to alert the system of any faults detected. Furthermore, its small size and low power consumption make the device a great choice for a wide range of applications.
