This makes it a desirable choice for implantable devices, as it can easily be integrated into the device design, allowing for faster and more efficient performance.

Working Principle

The 69CNQ135SM is a full-bridge rectifier array, meaning that it uses both positive and negative rectifier bridges to control the applied voltages. In order to control the voltages, the rectifier bridges are connected to two linear regulators which are connected in series, allowing for efficient voltage regulation. The regulators can be adjusted independently, allowing for greater control over the applied voltages. Furthermore, the 69CNQ135SM is designed to minimize losses under conduction, which improves its overall efficiency at all output voltages.

The soft-start circuit of the 69CNQ135SM is designed to slowly transition its output voltage to the target voltage, which helps to reduce any voltage spikes and protect both the components in the array and whatever device the rectifier array is being used to power. Additionally, the short-circuit protection circuit is designed to provide reliable operation, as it prevents the rectifier array from outputting any voltage if it detects a short-circuit.

The 69CNQ135SM rectifier array also offers low EMI, as its line frequency ripple is minimized by a patented frequency-shift-control technology, allowing for more optimal performance even under high line frequencies. The 69CNQ135SM also features a low turn-on time, allowing for fast transition from standby mode to full operation.

Conclusion

The 69CNQ135SM rectifier array is a versatile and reliable piece of integrated circuitry which offers numerous features and capabilities. It can be used in a variety of applications, ranging from automotive to consumer electronics and even medical implant designs. Its innovative protection circuit, soft-start technology and short-circuit protection all make it a safe and reliable choice for any number of applications.
