BU4947F-TR

A BU4947F-TR is a type of transistor-transistor logic (TTL) integrated circuit (IC) supervisor. This type of supervisor is designed to offer reliable voltage monitoring and inrush current suppression in applications such as security and automotive electronics, multimedia and communication systems, and other applications that require reduced power supply noise and power saving measures. In many cases, it is also used as a reset IC for a wide range of processors, microcontrollers and other systems.

The BU4947F-TR has a variety of features that make it ideal for a wide range of applications. Its low power consumption, high accuracy voltage monitoring, and protection against inrush currents and power supply noise make it an ideal choice for applications where performance and reliability are key requirements. The BU4947F-TR also has a variety of integrated reset outputs, including low voltage reset, open drain reset and an active low reset.

The working principle of the BU4947F-TR is based on comparing against two reference voltages. The first reference voltage is set by the Vref pin, and the second reference voltage is set by the VIN pin. When the voltage level of the VIN pin is below the Vref pin, the BU4947F-TR will switch into reset mode and output a reset for the system. The reset signal can be either active low or open-drain depending on the configuration of the BU4947F-TR.

The BU4947F-TR is easy to use and requires very little external components for operation. It requires a 1µF capacitor connected between the VIN and GND pins for suppression of inrush currents, and a voltage divider of 10k resistors to the Vref pin for setting the reference voltage. To connect the reset signals, two open-drain outputs or one active low output can be used, depending on the application.

The BU4947F-TR\'s design also makes it suitable for a variety of applications, especially where reliability and power saving measures are essential. Its integrated reset and tolerance of wide input voltage ranges eliminate the need for additional external components and make it an ideal choice for use in automotive electronics, multimedia and communication systems, and many other applications.

The BU4947F-TR is a versatile and reliable integrated circuit supervisor, making it the ideal choice for a wide range of applications. Its simple and versatile design, combined with its low power consumption and high accuracy voltage monitoring, make it a suitable choice for many applications where reliable performance and power saving are essential.
