The MAX6719AUTTGD3+T Supervisors is an advanced autosensing IC supervisor which can be used for reset, sequencing, push-button power sequencing, precision power sequencing and OV/UV tracking for embedded system. It has many other features that can help make power supply design simpler, such as a wide operating voltage range, low quiescent current, fast start-up time, programmable reset duration, ENABLE pin control, and a watchdog circuit. The MAX6719AUTTGD3+T can be used for a variety of applications, such as automotive, industrial, and medical.

The MAX6719AUTTGD3+T Supervisor contains a sophisticated, low-power autosensing reset circuit. This circuit can sense the power supply ramp rate, and it can quickly and accurately initiate a reset when programming begins or when the power supply voltage falls below the reset threshold. It can also detect soft faults, such as brownout or under-voltage conditions, and then take action to reset the system without waiting for the power supply to reach a full reset level. This type of reset circuitry is useful for applications that need to restart quickly and reliably.

The reset circuit also includes two delay circuits, a push-button reset circuit, and a watchdog timer. The delay circuits can be used to ensure that the power supply has enough time to stabilize before the reset circuit is engaged. The push-button reset circuit provides an easy way to hold the reset active for a predetermined amount of time. This is useful for applications that require resetting a system in a controlled manner. The watchdog timer can be used to detect if the system is not functioning properly, so that it can reset it before the problem causes further damage or loss of data. The watchdog timer can also be used to alert the user or the system of a problem.

The MAX6719AUTTGD3+T Supervisor also features an auto-sensing OV/UV tracking circuit. This circuit monitors the supply voltage and can alert the system when it approaches a certain limit. This is especially useful for applications that require precise voltage control, such as in industrial or medical applications. This tracking circuit is also useful for systems that need to maintain a precise output voltage level, such as in power-over-Ethernet (PoE) applications. This can help to prevent damage or data loss that can occur due to over-voltage or under-voltage conditions.

The MAX6719AUTTGD3+T Supervisor is a versatile, reliable and low-power solution for reset and sequencing applications. Its autosensing reset circuitry can detect power supply ramp rate and quickly initiate a reset; its delay circuits and push-button reset allow for controlled reset processes; its watchdog timer helps protect the system from malfunctions; and its OV/UV tracking circuitry ensures precise voltage control. The MAX6719AUTTGD3+T Supervisor can be used in a variety of applications, such as automotive, industrial, and medical.
