IPS1025HFQ M0T5 VIPower High-Side Switch

STMicroelectronics' IPS1025HFQ is a monolithic architecture in M0T5 VIPower Technology assembled in a QFN48L (8 mm x 6 mm) package. The IC is a single high-side switch device 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 8.65 V up to 60 V, but the breakdown voltage on the supply pin can reach 65 V.

The output stage is an N-channel PowerMOSFET with a typical R_DS(ON) of 12 mOhm at ambient temperature, internally limited at 2.5 A minimum output current. The ICs can set two current limitation levels (ILIMH-X and ILIML-X), purposing the smart driving of loads such as bulb lamps and loads with initial peak current requests as capacitive ones.

The switch has embedded protections with two couples of current limitation thresholds and levels (IPKH, ILIMH per a DPK time and IPKL, ILIML) and integrated diagnostics, making the devices suitable for realizing functional, robust machinery with loads with initial peak current requests.

The IPS1025HFQ offers power on/off delay time lower than 60 μs, making it suitable for safety integrity level (SIL) application requirements for interface type C (or D) Class 3. The STEVAL-IFP040V1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS1025HFQ (single high-side smart power solid state relay) in a digital output module connected to 2.5 A (max.) industrial loads.

The IPS1025HFQ is monolithic single device that can drive capacitive, resistive, or inductive loads with one side connected to ground. The IC is specifically designed to drive heavy loads with extremely low power dissipation in a PLC module or on driving unidirectional motors in vending machine applications.
