STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across a wide range of electronics applications, has launched a dual high-side switch that enables smart driving of capacitive loads with high startup currents.

ST announced on the 9th that it has recently launched its latest high-side switches, the IPS2050H and IPS2050H-32, which support two programmable current limits.

This new dual-channel switch supports an input voltage range of 8V to 60V and can withstand up to 65V at the input pins, ensuring flexibility and robust performance in industrial applications.

Integrated power MOSFETs have low Rds(on), high energy efficiency, and low heat loss.

Additionally, the MOSFET single pulse avalanche energy of better than 1J at 2A enhances the reliability of inductive load handling. An active clamp that supports fast demagnetization is also provided.

For IPS2050H, the main current limit can be programmed up to 2.5A, making it suitable for driving loads and equipment controlled by PLC modules, such as factory automation I/O peripherals and CNC (Computer Numerical Control) machines, as well as general resistive, inductive, and capacitive loads.

The IPS2050H-32 supports a higher maximum current limit of 5.7A, allowing it to be used with unidirectional motors in equipment such as vending machines.

Current activation thresholds and limits can be configured using external resistors. An external capacitor allows for smart driving of capacitive loads by setting a startup current limit time.

It also has a wide range of built-in protection and diagnostic functions, including UVLO (Under-Voltage Lock-Out) and protection against overvoltage, overload, short-circuit, ground disconnection, and Vcc disconnection, enhancing safety and reliability.

Overload and joint overheating events are indicated by individual fault signals for each channel. Additional sensors are also provided for case overheating protection. This switch meets the IEC 61000-4-2 ESD, IEC 61000-4-4, and IEC 61000-4-5 specifications for ESD, fast transient response, and surge immunity.

The provided demo board and software allow quick evaluation of drive and diagnostic capabilities when connected to industrial loads.

This board includes the X-NUCLEO-OUT03A1 and X-NUCLEO-OUT04A1 digital output expansion boards for use with STM32 Nucleo development boards, and the associated X-CUBE-OUT3, STSW-OUT03F4, and STSW-OUT03G4 software drivers.

In addition, it supports the source code of the STSW-IFAPGUI graphical user interface so that users can implement it across industrial automation environments.

The IPS2050H and IPS2050H-32 are available in a compact, space-efficient PowerSSO-24 package and are available now for $3.19 in quantities of 1,000.
