PMIC (Power Management Integrated Circuit) - Supervisors are a family of integrated circuits that are responsible for supervising the power supply lines of electronic circuits.It is composed of a supervisor chip and its associated circuits.The supervisor chip mainly monitors the power supply voltage and system reset, but also contains additional features such as software reset and power-on delay circuits.TLC7705QPWRG4Q1 is a PMIC - Supervisor, which includes an on-chip reset circuit and an internal voltage reference.The voltage reference is used to generate an internal reference voltage, whose output can be compared with an externally applied reference voltage after passing through a resistor divider.

The TLC7705QPWRG4Q1 provides three functions:reset circuits, timers and voltage references.It has a 200mV reference, providing an ideal source of stable voltage to all kinds of microcontroller, digital signal processor, flash memory and more.The preset reset circuit has stable and reliable voltage monitoring of the system power supply, satisfying different requirements of many applications.

The TLC7705QPWRG4Q1 includes a power-on reset circuit, under-voltage detector, timer and voltage sensor.The power-on reset circuit (POR) immediately resets the system power supply when it drops below a preset threshold or when external reset signals are activated.The under-voltage detector (UVD) monitors pre-set voltage levels and sends out an active-low reset signal whenever the voltage level drops below the pre-set threshold.The timer circuit is a programmable delay timer with a range of 0.25 to 1.75 minutes.The voltage sensor detects a low voltage and sends an active-low reset signal.

The TLC7705QPWRG4Q1 can be used in a variety of applications, such as server and storage system control, power control, computer peripherals, and automotive applications.It is suitable for any system which requires robust over-voltage and under-voltage protection.In terms of working principle, the TLC7705QPWRG4Q1 monitors the voltage of the power supply and sets the output signals accordingly.When the detected power supply voltage is lower than the preset threshold, a reset signal is output.Also, when the reset is activated, the internal timer will delay a reset signal for a pre-defined length of time.This allows for a system reset even when the power supply is unstable due to external conditions.

TLC7705QPWRG4Q1 is an efficient PMIC - Supervisor.The combination of reset circuits, timers and voltage reference make it suitable for use in monitoring and resetting of system power supply.With six pins, it is compact and highly integrated.It also has a wide operating temperature range, making it ideal for use in applications requiring high reliability operations in various environmental conditions.
