It is a power distribution switch and load driver, designed for specific applications with low power requirements. It can be used for various low voltage applications, such as LED lighting, automotive, industrial and communication systems.

General Features of VN5E016AFHTR-E

Externally, the VN5E016AFHTR-E has 6 pins, which are the ground pin, the power on/off control pin, the low voltage detection pin, the logic supply pin and the output power pins. Internally, the VN5E016AFHTR-E includes two power MOSFETs, a current sensing circuit and a protection circuit. It is a 100%-integrated device that requires minimal external components. It has a low quiescent current of 10µA, and an overall power dissipation of only 0.3W.

VN5E016AFHTR-E has an adjustable output voltage and current, with a maximum output current of 1A and a maximum output voltage of 17V. It also has an over-voltage / over-temperature protection, UVLO protection and fault flag indication, making it a highly reliable PMIC for many low power applications.

Functional Principle of VN5E016AFHTR-E

The VN5E016AFHTR-E is a PMIC with two power MOSFETs. The core function of the VN5E016AFHTR-E is to switch and distribute power between two of its pins. It has two inputs, which are the power on/off control pin and the low voltage detection pin. The power on/off control pin receives a signal to either enable the power Mosfet or to turn it off. The low voltage detection pin is used to detect the voltage level which is to be maintained.

The VN5E016AFHTR-E also has a current sensing circuit and a protection circuit for various operational aspects. The current sensing circuit senses the output current of the VN5E016AFHTR-E and turns off the power Mosfet if the maximum current rating is exceeded. The protection circuit includes an over-voltage, over-temperature and UVLO protection circuit, as well as a fault flag indication.
