The MAX6385XS38D5-T is a power management integrated circuit (PMIC) -- supervisors. It offers solutions to many challenges faced in the power supply distribution of consumer electronics, industrial and automotive applications. The power supply architecture consists of a main regulator, secondary regulators, and low-voltage-loops to ensure that the power supply is always in compliance with the system power requirements. The MAX6385XS38D5-T implements a variety of features and includes on-chip correction systems to address issues such as transient response, supply voltage regulation, and over-current protection.

The MAX6385XS38D5-T is designed for advanced power management. It provides the means for advanced sequencing, ultra-low noise operation, flexible voltage monitor, and monitoring of supply voltage deviation. It integrates synchronous rectifier FETs, hence simplifying power management board design.

The MAX6385XS38D5-T provides a high-efficiency power solution with its integrated PWM-mode synchronous buck switching regulator. The regulator includes a fully-featured adaptive loop response control system that reduces the output voltage ripple. The high-performance gate driver circuit can drive an N-channel MOSFET with up to 10A load. It is designed for an output voltage range of +/- 2.5V.

The MAX6385XS38D5-T provides an industry-leading low-noise operation and industry-leading performance at low operating frequencies of up to 500kHz. It features an integrated voltage monitor that allows the user to customize the monitor threshold and has adjustable output voltage accuracy. There is an on-chip over-current protection that trips upon detection of an over-current event.

The MAX6385XS38D5-T integrates two programmable regulators into one chip: A low-dropout (LDO) regulator and a low-noise linear regulator. The LDO regulator provides a dropout voltage of < 200mV at current loads up to 240mA while the low-noise linear regulator provides a dropout voltage of <200mV at currents up to 25mA. Both regulators are programmable and offer individually adjustable output voltages.

The MAX6385XS38D5-T offers a wide range of features for system power management, including an adjustable output voltage accuracy, on-chip monitoring of input power movement and over-current protection, pin selectable low-noise and high-efficiency operation, and integrated sensing elements for output current and voltage. All of these features make it suitable for a wide range of applications, from automotive to industrial, in which the power supply is expected to operate reliably, efficiently and with minimal noise.

The MAX6385XS38D5-T also features a ULVM (under-voltage lockout) circuit that prevents unauthorized use. It provides an adjustable USB-C Type-C voltage input range and has a soft-start circuit to ensure smooth operation at power-up, as well as an automatic spike-control circuit to reduce the radiated emissions.

The MAX6385XS38D5-T provides all the necessary features for advanced power management, including an adjustable output voltage accuracy, on-chip monitoring of input power movement and over-current protection, pin selectable low-noise and high-efficiency operation, and integrated sensing elements for output current and voltage. This makes it a top choice for those in need of a reliable and efficient power management solution.
