The MAX6862UK32+T is a precision initialization and reset supervisor IC specifically designed for use in power-sensitive applications. The IC operates from a single +2.5V to +5.5V energy source and is available in both the space-saving 8-pin uMAX® package and the 16-pin TQFN package. This device is ideal for use in applications such as FPGAs, DSPs, microcontrollers, and motor controllers.

The MAX6862UK32+T provides several features, including a low-power initialization and reset supervisor with two manual reset (MR) inputs, an automatic power-on reset (POR) with adjustable timeout, a power-fail supervisor, and an adjustable power-switch reset threshold with built-in watch-dog timer (WDT) and push-pull or open-drain power switch outputs. The device also provides flexible interrupt and reset filtering.

The MAX6862UK32+T\'s low-power initialization and reset feature handles manual and power-on reset (POR) functions. Manual reset inputs are used to initialize the system and respond to power-fail events. The user-programmable POR timeout controls the system\'s power-on reset duration.

The power-fail supervisor monitors the positive and negative power supplies for out-of-tolerance conditions. If either power source falls below a user-programmable threshold, the on-chip power-fail gate asserts the device\'s RESET output.

The adjustable power-switch reset threshold is an adjustable power fail comparator that monitors the system power level; the adjustable power-switch threshold determines when the WDT and push-pull or open-drain power switch outputs are asserted.

The MAX6862UK32+T automatically transitions the state of the system during power-up and power-down sequences, ensuring orderly system initialization and system shutdown. The device supports an interrupt output, which can be triggered by a power-fail event or the expiration of the POR timeout period. The interrupt output can be used to trigger a interrupt controller to contend for system resources in response to power-fail or power-on events.

The MAX6862UK32+T is designed for a wide range of low-power applications and is ideal for use in DSPs, microprocessors, and other power-sensitive systems. The device is available in both the space-saving 8-pin uMAX® package and the 16-pin TQFN package, making it suitable for a wide range of applications, from space-constrained applications to more demanding applications.
