As a leading company in the semiconductor field, STMicroelectronics has always relied on its outstanding technology and innovation capabilities to continuously launch high-performance products that meet market demand. And IPS1025HF is another masterpiece in the field of power switches. Once this component was launched, it attracted widespread attention in the electronics industry. Many engineers and electronics enthusiasts have turned their attention to it, expecting it to show extraordinary strength in practical applications.

Performance highlights

(I) Extreme response, safe escort

In the current era of safety first, for many safety systems, time is life, and every second or even every microsecond is crucial. IPS1025HF performs well in this regard. Even if the on-off status of the Vcc power supply is taken into consideration, its on-off response time is still less than 60μs. How critical is this feature? Imagine that in some industrial scenarios with extremely high safety requirements, such as automated production lines, once an abnormal situation occurs, the power supply needs to be quickly cut off to protect the safety of equipment and personnel. The ultra-fast response of IPS1025HF can ensure that the power on and off operation is completed in a very short time, providing a solid guarantee for the safety protection system to reach the specified safety integrity level (SIL), and effectively reducing the risk of accidents.

(II) Wide voltage adaptation, stable and reliable

The industrial environment is complex and changeable. IPS1025HF has a strong "pressure resistance" ability. It supports a wide voltage input of 8.65V to 60V, and the maximum withstand voltage of the input pin can reach 65V. This means that whether in remote areas with unstable voltage or in industrial sites with severe electromagnetic interference and frequent voltage fluctuations, it can operate stably like a determined warrior. For example, in some harsh industrial conditions such as oil extraction and chemical production, other components may frequently fail due to voltage problems, and IPS1025HF, with its excellent wide voltage adaptability, has laid a solid foundation for the stable operation of the equipment.

(III) Flexible current limiting, worry-free load

Different loads are like machines with different "appetites" and have different current requirements. IPS1025HF is similar to the single-channel and dual-channel products in STMicroelectronics' intelligent power switch series, with two programmable current limit settings. This feature gives users great flexibility. When the power switch is activated, users can set a high current limit value according to actual needs. For example, when a light bulb starts, a large initial peak current is required to light the filament; when a motor starts, it also needs to overcome a large inertia, which also requires a high initial current; and the current demand of the capacitive load is also large at the beginning of charging. In these cases, the programmable current limit setting of IPS1025HF can be used to meet the needs of special loads and improve the flexibility of load driving.

(IV) High efficiency and energy saving, low consumption operation

In today's advocacy of energy conservation and environmental protection, the energy efficiency performance of electronic components has also attracted much attention. The output stage of IPS1025HF uses an N-channel power MOSFET with a typical on-resistance Rds (on) of 12.5mOhm at ambient temperature. Lower on-resistance means less heat and lower energy loss when current passes through, thus ensuring high energy efficiency of the switch. At the same time, the minimum output current of the MOSFET is limited to 2.5A. This ingenious design enables it to distribute electrical energy more reasonably when working and avoid unnecessary energy waste. Coupled with its maximum single pulse avalanche energy of 14J, it can handle inductive loads more reliably, further improving the overall energy efficiency performance. Long-term use can save a lot of electricity bills for enterprises and contribute to green environmental protection.

(V) Multiple protections, stable operation

In order to ensure safe and reliable operation in various complex situations, IPS1025HF is equipped with a series of complete safety functions. The undervoltage protection function is like a keen "voltage guard". When the input voltage is lower than the set threshold, it will act quickly to prevent the component from failing to work properly or being damaged due to low voltage; overvoltage protection is a solid "line of defense". When the voltage is too high, the power supply is cut off in time to avoid irreversible damage to the component caused by excessive voltage. Functions such as overload protection, short circuit protection, ground disconnection protection, and Vcc disconnection protection also protect the safe operation of components from different angles. In addition, diagnostic pins are set on the chip, including independent output overload and junction overheating signals, and a thermal sensor is added to detect whether the package temperature is too high. These diagnostic pins are like "health monitors" for components, which can provide real-time feedback on the working status of components. Once an abnormal situation occurs, users can take timely measures to ensure the stable operation of the entire system.

With its fast on-off response time, IPS1025HF can ensure that PLC responds quickly at the moment of receiving the control signal to achieve precise control of the equipment. It also shows its prowess in factory automation I/O peripherals. For example, in the sensor power supply system of an automated production line, IPS1025HF can provide a stable and reliable power supply for the sensor, and in the event of an abnormal situation, it can quickly cut off the power supply to protect the sensor from damage. At the same time, its wide voltage adaptability and perfect protection function also enable it to operate stably in complex industrial environments, providing a strong guarantee for the efficient and reliable operation of industrial automation.
