STMicroelectronics (NYSE: ST), a global semiconductor leader serving customers across a wide range of electronics applications, has launched a single-channel load switch for high-start-up current applications that protects products from overload and overheating.

ST announced on the 19th that it has launched the programmable single-channel versions of the high-side switches IPS1025H and IPS1025H-32.

Equipped with built-in protection against undervoltage, overvoltage, overload and overtemperature, these devices can intelligently drive capacitive, resistive or inductive loads that consume high startup currents.

The IPS1025H and IPS1025H-32 have different internally programmed current limits.

The current limit of IPS1025H is 2.5A, and that of IPS1025H-32 is 5.7A. In addition to the main current limit, each switch provides user-programmable secondary current limiting to handle high initial start-up current capacitive loads.

The limit value and duration are set using external resistors and capacitors.

These compact devices feature a very wide voltage range of power supply and input pins, from 8 V to 60 V, and can withstand up to 65 V on the input pins, ensuring stable performance in industrial applications.

The IPS1025H can be used to drive loads typically controlled by PLC modules or for factory automation equipment such as I/O peripherals and CNC machines.

The IPS1025H-32, with its higher maximum current limit, is ideal for unidirectional motors in equipment such as vending machines.

Integrated MOSFET switches provide excellent energy efficiency and low heat dissipation with low Rds(on) of less than 25 mΩ up to TJ = 125°C.

This MOSFET enhances reliability by handling inductive loads with a single-pulse avalanche energy equivalent to 14 J at 2 A. The integrated active clamp provides fast demagnetization.

ST's new programmable switches incorporate extensive protection and diagnostic features to enhance safety and reliability by handling undervoltage, overvoltage, overload, short-circuit, ground, or power supply rail disconnections.

It also indicates overload and joint overheating events with individual error signals. An additional sensor is provided for case overheating protection.

This switch meets the IEC 61000-4-2 ESD and IEC 61000-4-4 and IEC 61000-4-5 specifications for ESD and fast transient and surge immunity.

Demo boards and software are also provided for quick evaluation.

It includes software drivers for the X-NUCLEO-OUT05A1 and X-NUCLEO-OUT06A1 digital output expansion boards for use with STM32 Nucleo development boards, as well as the X-CUBE-OUT5 software package that extends the functionality of the STM32.

The source code for the graphical user interface (STSW-IFAPGUI) is also provided, allowing users to realize a complete industrial automation environment on their desktop.

The IPS1025H and IPS1025H-32 are currently in production in the PowerSSO-24 package, priced at $3.51 in quantities of 1,000.
