MAX6389XS20D1-T is one of the Power Management Innovation Complex (PMIC) - Supervisors in the market. This device is a low power, low voltage supervisor integrated circuit (IC) that provides a cost-effective, ultra-low power general supply monitoring for many industrial, consumer, communication and computing products. It is generally used for system reset, power-on/low reset and power conditioning applications.

MAX6389XS20D1-T is designed to lower standby current and offer broad, integrated voltage monitoring capability with low voltage threshold accuracy. Its low power features can extend battery life and simplify power supply designs with integrated, single-chip reset, power-on reset and undervoltage lockout functions. This IC has a unique power-on reset circuit, requiring a minimum of external components, creating a small and cost-effective system design.

The MAX6389XS20D1-T device is functionally suitable for many applications, including: Distributed power systems, Automotive, Telecom and Networking, Industrial control systems, Embedded systems and various consumer products. It is available in 7 different packages: SOT23-5, SC70-5, TDFN-3x3, SOIC-8, MSOP-8, TSSOP-8, and UDFN-3x3.

This device works in a very basic principle. It monitors and trips an active-low reset after an asserted reset interval, independent of input voltage and temperature. It also supports the typical power-on reset, low voltage reset and under voltage lockout functions, with a built-in reset timer. An internal monitoring circuit continuously monitors the input voltage and will trip an active-low reset when it falls below a preset threshold. This active-low reset can either be issued as a power-on reset or a low voltage reset.

In addition to these features, the MAX6389XS20D1-T also offers extended flexibility and control. It is equipped with an adjustable reset interval, available in 20 or 40 milliseconds, or disabled (ON/OFF). The reset interval can be adjusted to match the most demanding Sequencing reset requirements, or configured for standby or power saving modes. This device can be used as an autonomous reset timer, or together with a manual/external reset for monitoring system status.

The MAX6389XS20D1-T is a one-stop solution for many of the signaling and control needs of the power supply design with built-in reset, power-on reset, undervoltage lockout and reset timeout features, all integrated onto a single chip. Its low power features provides cost-effective and reliable power monitoring and control, while allowing designers to maximize the power efficiency of their products. It is offered in a wide range of packages, suitable for different type of end-products and applications.
