TL7705ACDR

TL7705ACDR is a popular PMIC - Supervisors integrated circuit from Texas Instruments. It has numerous applications in power supply systems where power demand is constant. This device offers two or three outputs to provide multiple current limit and thermal protection for equipment load. It also provides reset signals for system power management control.

TL7705ACDR Application fields are primarily used in industrial, automotive, and consumer electronics devices. It can protect against over-voltage and under-voltage conditions and thermal overloads. It also provides protection against reversed polarity input and over-current detection by using an external sense resistor. This device can protect applications from up to 35v in automotive and industrial environments, and up to 37v in consumer electronics.

The working principle of TL7705ACDR relies on detecting the input voltage and output current of the system power supply and triggering reset signals when these thresholds are crossed. The TH97 is a comparator you can use in conjunction with a voltage divider for over-voltage detection, and a comparator for under-voltage detection. The die temperature of the device must also be monitored as thermal protection. The output of the die temperature sensor is compared against a reference voltage by the TCTC pin, triggering a reset signal when the threshold is crossed.

TL7705ACDR is a versatile and widely used device in PMIC - Supervisors applications. It can provide multiple power supply protections through its integrated circuits, and reset signals for power management control. It is commonly used in consumer electronics, automotive, and industrial applications, and can protect against wide range of over-voltage, under-voltage, thermal, and reversed polarity input conditions.
