Introduction

The CPH6538-TL-H is a high voltage, high current bipolar transistor array, part of a series of power amplifiers from ROHM Semiconductor. It is available for use in a variety of applications thanks to its wide range of operating voltages (which stretches from -50 to 800V), and its ability to deliver up to 20A of average collector current.

Application Field

The CPH6538-TL-H’s ability to handle large current and voltage levels makes it suitable for use in automotive and industrial applications. It is designed to be used in high-power systems, such as adjustable-speed motor drive systems, or as a power amplifier in automotive audio and Radio Frequency (RF) applications.

Its resistance to vibration, EMI/RFI, humidity, and operating temperature makes it suitable for use in temperature-dependent systems, such as telecommunications, HVAC control, and industrial process control systems. It is also well suited for automotive applications, such as in airbag systems, 10-motor-based systems, wheel-angle-sensor systems, power steering systems, and lighting systems.

Working Principle

The CPH6538-TL-H works by using two bipolar transistors connected in parallel. When one transistor is “on”, the other is “off”, allowing the current to flow through one of the transistors at a time. This creates a “switching circuit”, which allows the CPH6538-TL-H to switch quickly between high and low resistances, and to maintain a constant output voltage.

When the transistor is “on”, there is a high voltage across the collector and emitter of the transistor, which allows current to flow through the circuit. When the transistor is “off”, no current flows through the circuit, and the voltage across the collector and emitter is low. This allows the CPH6538-TL-H to control the amount of current flowing through the circuit, and to regulate the output voltage depending on the application.

Conclusion

The CPH6538-TL-H is a high voltage, high current bipolar transistor array, designed for use in a variety of high-power applications. It is suitable for use in automotive and industrial applications, thanks to its resistance to vibration, EMI/RFI, humidity, and operating temperature. Furthermore, its ability to quickly switch between high and low resistances, and to regulate the output voltage make it ideal for use in temperature-dependent systems.
