PMIC refers to a power management integrated circuit, which combines linear and non-linear functions such as voltage regulation, current limit and energy control to realize efficient power management of the system. It is an important component for modern electronic products.

TL7702ACDRG4 is an advanced supervisor IC (Supervisor IC, Supervisory IC), which is the current most advanced power management solution. Through its "three-finger" application field and advanced working principle, TL7702ACDRG4 can provide high performance, stability and reliability to the entire system power management.

Application Field of TL7702ACDRG4

The TL7702ACDRG4 is a voltage supervisor for general use, often used for monitoring a wide range of industrial applications, such as server and storage systems, automotive systems, telecommunications base stations, instrumentation, medical equipment and home entertainment systems. The device also provides two digital outputs that can be used to monitor low and high thresholds.

Working Principle of TL7702ACDRG4

TL7702ACDRG4 adopts a “three finger” workmanship, designed to generate accurate reset signals under a variety of operating conditions. The main component of this IC is a precision bandgap reference and two comparators. It has two input voltages, VT, full name is “VolTage”, and VCC, both of which are impedance balanced about 1.205V. When the voltage on both these inputs is equal, the comparator output can be triggered and the reset output is pulled low. When VCC>VT, the reset output is pulled high and waits for the next trigger. This is the general working principle of the TL7702ACDRG4.

TL7702ACDRG4 also includes a dual-channel watchdog timer, which is independent from the reset circuit, and detects any abnormal conditions in the system. For highly technical applications, this IC can also detect the operating temperature range with an integrated NTC temperature sensor — adjustable.

The TL7702ACDRG4 supports a wide range of input voltages, including 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V and 1.05V. It also has two digital outputs that can be used to monitor low and high thresholds. And it has integrated protection against short circuits, surges and reverse polarity, which provides excellent protection against the harsh conditions of industrial environment.

TL7702ACDRG4 is an innovative and advanced supervisor IC, which is widely used in industrial applications because of its wide range of features and its ability to work under different conditions. Due to its high performance and stability, TL7702ACDRG4 has become a popular choice for industrial and commercial applications.
