The MAX6892ETJ+ is a voltage supervisor and reset IC that provides circuit-handling instruction for advanced microcontrollers and logic circuits. It belongs to the class of PMIC (Primary Mechanical Interface Control) - Supervisors. This product has several features that make it ideal for applications that are constantly exposed to negative voltages and supply noise. MAX6892ETJ+ is most commonly used in battery-operated medical sensors and automotive microcontrollers.

The MAX6892ETJ+ is a low-power CMOS voltage supervisor that prevents system failures caused by negative voltages, brownout conditions and supply noise. The device has two operating ranges, one for normal operation and one for low-power monitoring. In the low-power state, it debounces the input signal and issues a reset on asserted logic level. The device also enables its internal comparator by allowing a second voltage checking point.

The MAX6892ETJ+ is designed to operate with a wide range of input voltages, including positive and negative supplies. It features an on-chip comparator which provides an adjustable voltage limit, in addition to a programmable reset delay. The device provides active low open-drain outputs which allow further control in the system.

The MAX6892ETJ+ includes an auto-recovery reset for quick recovery from a brownout condition. It also has internal hysteresis which eliminates excessive current consumption during shut-off transitions. Additionally, the device also has an automatic expiry evaluation that enables system self-diagnosis. This feature allows the device to become active immediately after a system failure.

The MAX6892ETJ+ is designed to run on a wide range of input voltages. It offers a shutdown supply range of -0.3V to +3.6V and a low-power supply of -0.3V to +1V. The device also features selectable output thresholds, with a programmable delay of 1.6ms minimum. This feature is ideal for automotive microcontrollers and other power supply sensitive applications.

The MAX6892ETJ+ also offers a temperature-compensated reset delay, which can be adjusted to extend the reset assert time at high temperatures. In addition, the device includes an adjustable timeout and a low-voltage monitoring input. The device features a power-up reset circuit and an integrated watchdog timer, which allows the MAX6892ETJ+ to able to detect a failure condition in the system.

Compared to other PMIC-Supervisor devices, the MAX6892ETJ+ is a low-power and efficient solution for design engineers. It provides an active low reset signal and an adjustable timeout for reliable protection against negative voltages and supply noise. In addition, the device is designed for automotive and medical application for reliable operation over a wide temperature range.
