STMicroelectronics has introduced the new dual-channel high-side switches IPS2050H and IPS2050H-32 that permit two programmable current-limit values for smart driving of capacitive loads that draw high startup current. These devices have an input voltage from 8V to 60V and can withstand a voltage of up to 65V on the input pin, ensuring robust performance and flexibility in industrial applications. Moreover, low RDS-ON (≤ 50 mΩ up to TJ = 125 °C) make these ICs suitable for applications with up to 2.4A / 5.6A steady-state operating current.


The IPS2050H allows the main current limit to be programmed up to 2.5A for driving loads controlled by a PLC module and for use in equipment such as factory automation I/O peripherals, Computer Numerical Control (CNC) machines, and general driving of resistive, inductive, and capacitive loads. The IPS2050H-32 has a higher maximum current limit of 5.7A for use with unidirectional motors in equipment such as vending machines. The current activation threshold and limit values are configurable using external resistors. An external capacitor sets the duration of the startup current limit for smart driving of capacitive loads.


In addition, extensive built-in protection features and diagnostics enhance safety and reliability, including Under-Voltage Lock-Out (UVLO) and protection against overvoltage, overload, short-circuit, ground disconnection, and Vcc disconnection.
