TL7700CDGKT

TL7700CDGKT is a supervisor device that is part of PMIC (Power Management Integrated Circuit) system. It is used to monitor several power supply rails and output voltage levels, and raise alarms when the voltage levels exceed the pre-set warning and supervision levels. TL7700CDGKT adopts a wide supply voltage range of 2.7V to 14V, and temperature range of -40℃ to ＋125℃, to meet the requirements of different system applications.

TL7700CDGKT\'s function is to detect, reset, and supervise the supply voltage level to prevent system malfunction. The specific role in which TL7700CDGKT operates is determined by its internal configuration, which consists of a watchdog timer, multiple voltage comparators and a power reset controller.

The voltage comparators use an internal reference voltage generated from an on-chip bandgap reference generator, which is compared to the supply voltage. When the supply voltage falls below the specified lower threshold, the voltage comparators will trigger a reset event to shut down the system. When the supply voltage rises above the pre-set upper threshold, a warning is triggered and the supervisor will capture the voltage level.

TL7700CDGKT is used to protect system against under-voltage events, such as brownouts and power sags, and alert the system of the presence of an over-voltage condition. It is also highly configurable, with the possibility to select from multiple reset sources, reset levels, supervisory settings and reset timeout settings.

The application field of TL7700CDGKT is mainly in data storage and communications infrastructure, industrial, automotive, healthcare and medical markets. In data storage and communications, it is used as a power diverter, allowing the system to continue operation even when the power supply is not optimal. In industrial, automotive and healthcare/medical applications, it is used to monitor critical voltage levels and raise alarms when these levels exceed the set thresholds.
