Power management integrated circuits (PMICs) allow for the control of the power supply to several components of a device, ensuring efficient use of current and improving system performance. Among several PMICs in the market, ZSM330GTC is an integrated supervisor chip that offers comprehensive protection for battery-type, DC-DC converter, and low-voltage networks. The chip integrates several functions, including overvoltage protection, undervoltage protection, time-delay protection, and thermal protection. All of these features come together to form an ideal power supply management solution.

The ZSM330GTC is a durable power supervisor ideal for industrial systems as well as consumer applications. It features a nominal operating voltage of 2.8 to 5.5V and offers unsurpassed accuracy in monitoring, detecting, and preempting overvoltage and undervoltage conditions. It also provides short-circuit and thermal protection, as well as MTTF lifetime monitoring. The chip supports up to 2V precision on positive overvoltage and negative undervoltage monitoring and includes two-step time-delay protection.

The ZSM330GTC has an extensive list of applications and an array of features that make it a great choice for a wide range of applications, including consumer electronics, industrial systems, automotive and medical electronics, communication and networking equipment, home entertainment systems, and more. Its many capabilities make it one of the most versatile power management chips on the market.

Apart from offering protection against overvoltage and undervoltage conditions, the ZSM330GTC also offers a range of features to extend its utility. The chip features two or three push-pull outputs and a power-on reset function with 60mV hysteresis.
