Introduction to 87CNQ020A

The 87CNQ020A is a rectifier array integrated circuit used to protect circuits from overvoltages and overcurrents. It is often used in automotive and home applications as a safety device. The device consists of two low-power low-voltage diodes and two settable current limits. It also has an integrated reverse bias protection circuit, power MOSFET, and zener diode.

Application Field

87CNQ020A is widely used in automotive and home applications. In automotive applications, 87CNQ020A can be used as a high-side switch, for voltage and current surge protection, for overvoltage and overcurrent protection, and for reverse battery protection. It is also suitable for applications that require higher current handling than that of a simple power MOSFET. In home applications, 87CNQ020A can be used in place of high-power power MOSFETs to protect circuits from overvoltages, overcurrents, and reverse battery connection. It is also suitable for applications like solar power systems, audio amplifiers, and power supply modules.

Working Principle

The 87CNQ020A operates by running current through two low-power low-voltage diodes configured in a bridge rectifier. When an overvoltage or overcurrent situation is detected, the two settable current limits will trigger the reverse bias protection circuit, the power MOSFET, and the zener diode to activate and cut off the electric current.The reverse bias protection circuit is used to ensure proper operation of the MOSFETs and diodes by providing an electric field to ensure that the current flows only in the direction of the reverse protected terminals. The power MOSFET then acts as a high-side switch and acts to rapidly cut off electric current. Finally, the zener diode acts to prevent any potential overvoltage conditions.

Conclusion

In conclusion, the 87CNQ020A is a highly useful integrated circuit used to protect circuits from overvoltage and overcurrent. It is suitable for automotive and home applications, and it employs a low-power low-voltage diode rectifier, two settable current limits, a reverse bias protection circuit, a power MOSFET, and a zener diode to ensure proper operation and safety in circuits.
