The TC427VPAG has been designed to meet the stringent demands of industrial, automotive, and telecommunications applications. Its electrical parameters and fast response time make it suitable for a variety of different applications where the need for precise power management is paramount.

Therefore, the TC427VPAG can tackle any challenge related to driving power transistors in these high demands applications. It is an excellent choice for circuits that must reliably control AC and DC motors, HVAC systems, or any circuit integrating multiple voltages.

Additionally, the TC427VPAG is a cost-effective solution for a wide range of embedded systems, such as those used in server racks or mobile devices. As such, it can help secure reliable system operation even in cooling systems, where it can help reduce cooling power requirements.

Working Principle

The TC427VPAG is a single-output power management IC, meaning it controls a single output. It works by enabling the selection of many output drive voltages, as it operates on a voltage supply range of either +8V to +36V or -15V to -60V.

The gate voltage of the output device is provided by the device’s internal circuitry, thereby eliminating the need to use any external components. More specifically, the internal gate drive is provided by a high-voltage, precision amplifier.

The output drive voltage range is increased by the introduction of a floating output stage, which allows for true output voltages ranging from +24V to -80V. This range is selectable via a single pin voltage selector. The device’s power output is also selectable from either 30 mA or 10 mA.

Moreover, the TC427VPAG integrates a power supply failsafe option, in case of an unexpected power failure. This feature minimizes the risks associated with catastrophic over-current conditions and ensures power management safety.

Conclusion

The TC427VPAG addresses the most demanding AC, DC and pulse-width modulation applications. Its advanced features and flexibility provide excellent control of power semiconductors within a wide range of supply voltages. This makes it an ideal choice for industrial, automotive, telecommunications, and other embedded system applications where fast and reliable power management is necessary.
