Introduction of HIP1013CBZA-T
The HIP1013CBZA-T is a PMIC designed to be used with N-channel logic level MOSFETs in hot swap applications. It provides active current-limited control of large capacitive loads, pre-biased or non-biased with over voltage and over current protection. It is available in a lightweight and compact 8-pin SOIC package for space-constrained applications.HIP1013CBZA-T Application Field
The application field of HIP1013CBZA-T includes telecommunications, computing, networking and portable medical instruments. It mainly used to provide a low resistive and active current-limited path to safely power up a device while protecting it from voltage and current imbalance.The HIP1013CBZA-T offers a wide range of current limit protection, 50mV to 490mV, with a built-in thermal shutdown circuit and hot warning especially suitable for power sensitive systems. The active current-limited protection further helps ensure better system reliability.HIP1013CBZA-T Working Principle
HIP1013CBZA-T works on the principle of proportional current driver, where the current limit is determined by an external resistor, usually connected to ground. The current limit is based on the same principle as that of a common low-side current-limiting MOSFET, in this case the MOSFET is positioned at the output of the current limit circuit.Once the output current reaches the current limit threshold, the voltage across the MOSFET begins to fall, which in turn activates the driver circuit. The driver circuit turns off the MOSFET, thus reducing the amount of current that can flow through it, limiting the output current. The current limit is also adjustable via an external resistor connected to the settings pins on the chip.Furthermore, the HIP1013CBZA-T includes an adjustable pre-bias start resistor, which helps ensure the device is safe to power up when exposed to live power lines. The device also includes a thermal shutdown circuit and a hot warning indication to protect the IC in case of excessive current draw.Conclusion
In conclusion, the HIP1013CBZA-T is a low cost PMIC that provides active current limiting for hot swap operations. It is useful for power-sensitive applications, such as telecommunications, computing, networking and portable medical instruments, where current limit protection is smartly implemented with pre-biased or non-biased voltages. With proprietary current limit settings and an adjustable pre-bias start resistors, the HIP1013CBZA-T helps ensure better system reliability.
