IPS1025H, IPS1025H-32, and IPS1025HF Single-Side Switches

STMicroelectronics' IPS1025H, IPS1025H-32, and IPS1025HF are a monolithic architecture in M0T5 VIPower technology and assembled in PowerSSO-24 package. The ICs are single high-side switch devices that can drive capacitive, resistive, or inductive loads with one side connected to ground (high side switch). The operating voltage is recommended in the range of 8 V up to 60 V, but the breakdown voltage on the supply pin can reach 65 V.

The difference between the IPS1025H and the IPS1025H-32 devices is the current limitation protection internal setting when all the remaining electrical parameters are equal. The output stage is an N-channel power MOSFET with a typical R_DS(ON) of 12.5 mΩ at ambient temperature, internally limited at 2.5 A minimum output current for IPS1025H and 5.7 A for IPS1025H-32.

The ICs set two different current limitation levels (ILIMH-X and ILIML-X), purposing the smart driving of loads (such as bulb lamps) and loads with initial peak current requirements as capacitive ones. The embedded protections with two couples of current limitation thresholds and levels (IPKH, ILIMH per a DPK time and IPKL, ILIML) and integrated diagnostics are suitable devices to realize functionally robust machinery with loads with initial peak current request.

The X-NUCLEO-OUT05A1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible environment for evaluating the driving and diagnostic capabilities of the IPS1025H (single high-side smart power solid state relay) in a digital output module connected to 2.5 A (max.) industrial loads. The X-NUCLEO-OUT06A1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible environment for evaluating the driving and diagnostic capabilities of the IPS1025H-32 (single high-side smart power solid state relay) in a digital output module connected to 5.7 A (max.) industrial loads.
