Resistor Networks, Arrays are widely used in modern electronics for their reliable performance over a wide range of conditions. The 744C083330JTR chip from Hong Kong Semiconductor Corporation is a bipolar transistor network Resistor Array that exhibits excellent power handling capability and features low power consumption, wide bandgap compatibility, and a number of other advantages. The following details the properties of the 744C083330JTR, its application field and working principle.

The Properties of 744C083330JTR Resistor Array

The 744C083330JTR is a low dat-rate PNP transistor Network Resistor Array that features a low on-resistance of 104 m2 and a high breakdown voltage of 8.6 kV. It features wide-band gap capability and offers excellent power handling capability at 10 A. In addition, the 744C083330JTR also offers a wide temperature range operation from -55C to + 125C and a long-term reliability of 1 million hours.

The 744C083330JTR Resistor Array is designed as a four-terminal resistor network integrated circuit with four isolated sections. Each section consists of a pair of resistors connected in series and then evenly split into two separate branches. The split branches are then connected to a pair of terminals. By controlling the on-resistance, the total resistance of the resistor network can be precisely tuned.

Application Filed of 744C083330JTR Resistor Array

The 744C083330JTR Resistor Array is suitable for a wide range of applications. Its high resistance accuracy and excellent reliability make it ideal for industrial, automotive, computer, and communication applications. The low on-resistance and wide temperature range also make it an ideal choice for arbitrating logic and neutral point clamps in DC/DC converters. The 744C083330JTR is also suitable for many other applications, such as, power management, battery charger, speaker protection, high-current sensing and control, and cell phone, Ultrasound, and other signal monitoring.

Working Principle of the 744C083330JTR Resistor Array

The 744C083330JTR Resistor Array is designed using standard CMOS technology and functions using four relatively simple mechanisms. During normal operation, the four resistors in each section are connected in two separate branches and then connected to a pair of terminals by controllable PNP transistors. The on-resistance of each transistor is controlled by the appropriate input voltage, allowing for the total resistance of the network to be precisely tuned.

The second mechanism is based of cascading voltage drop across the four resistors in each section. Using this technique, the 744C083330JTR is able to regulate the output voltage in DC/DC converters. The third mechanism is about the input current of the PNP transistors, which is controlled by the operating voltage. Lastly, the fourth mechanism is the inactive discharge of the NPN transistors to ensure that the circuit is fully isolated.

In conclusion, the 744C083330JTR Resistor Array is a versatile and reliable device. Its low on-resistance, wide temperature range, excellent power handling capability, and high resistance accuracy make it a perfect choice for many applications. It is the ideal choice for applications such as DC/DC converters, high-current sensing and control, and battery charger protection.
