The TPS3306-33QDRQ1 is a type of PMIC (Power Management Integrated Circuit) Supervisors designed to provide over-voltage and under-voltage protection for applications such as mobile devices and LED lighting solutions.

The device is particularly suited to portable and handheld applications, offering a small 6-pin Micro-3 package that offers an array of features such as automated reset or power-fail output control and temperature-regulated monitoring. It includes one adjustable overvoltage monitor input, one low-power low-line monitor input, one RESET output, and one power-fail output.

The TPS3306-33QDRQ1 can be used in applications such as mobile phones, tablets, ultra low-power audio products, USB wall chargers, notebook PCs, MFM hard drives, and battery management, where overvoltage and undervoltage protection is needed. The device also includes a variety of protection features including voltage and current limit protection, polarity reversal protection, fuse protection, temperature-controlled power-off protection, and micro-power standby.

The TPS3306-33QDRQ1 has an operating voltage range of 1.6V to 5.5V and an operating current of up to 50mA. This device incorporates a power-on reset circuit, which eliminates the need for an external reset circuit. In addition, it features an adjustable overvoltage monitor and a low-line monitor with hysteresis levels.

The device also offers an integrated on-delay timer that provides an adjustable delay in producing the reset or power-fail output with a range of 0.5-4s. This timer can be used to compensate for power supply droop or power supply noise. The timer also ensures that enough time is given to the system to latch the reset event.

The TPS3306-33QDRQ1 also includes an active overvoltage protection circuit that prevents the supply voltage from exceeding a preset voltage limit in order to protect sensitive circuits. Temperature-controlled power-off protection ensures that the device shuts down when its temperature exceeds a preset limit.

The TPS3306-33QDRQ1 also offers a configurable power-fail output, which can be used to indicate that the power has dropped below a preset point. This can be used to control the power-save mode of the system. The device also features an integrated voltage comparator and an adjustable voltage monitor with a hysteresis level, which can be used to detect overvoltage or undervoltage conditions.

The TPS3306-33QDRQ1 also features a latch-up protection circuit to handle current surges. The device also features an ESD protection circuit to protect circuits from electrostatic discharge. In addition, the device includes an integrated over-current protection circuit that can be used to protect circuits from over-current conditions.

The TPS3306-33QDRQ1 is available as a 6-pin Micro-3 package and is ideal for applications where small size and low power are required. This device is RoHS-compliant and rated for operation over a temperature range of -40°C to 125°C.
