STMicroelectronics has launched the IPS1025HF fast-starting high-side energy swap to be used in security techniques that require minimal power-on delay time.
The IPS1025HF responds to turn-on and turn-off alerts in lower than 60µs even contemplating the Vcc power-on and off, enabling protecting techniques to make sure a specified safety-integrity degree (SIL). That includes a really broad input-voltage vary from 8.65V to 60V and in a position to tolerate as much as 65V on the enter pin, the compact units stand up to harsh industrial working situations. Purposes embody energy management for programmable logic controllers (PLCs), merchandising machines, factory-automation I/O peripherals, and pc numerical management (CNC) machines.
Like comparable single-channel and twin units in ST’s clever energy swap household, the IPS1025HF has two programmable current-limit settings that enable the person to program a better present limitation worth at energy swap activation. This enhances flexibility for driving masses akin to bulb lamps, motors, and capacitive masses that demand excessive preliminary peak present.
The output stage is a N-channel Energy MOSFET with a typical Rds(on) of 12.5mOhm at ambient temperature, guaranteeing excessive power effectivity and low thermal dissipation. The MOSFET is internally restricted at 2.5A minimal output present and has single-pulse avalanche power as much as 14J, which boosts reliability for dealing with inductive masses. There’s additionally an built-in energetic clamp for quick demagnetization.
The swap contains safety in opposition to undervoltage, overvoltage, overload, brief circuit, floor disconnection, and Vcc disconnection. On-chip diagnostics embody particular person signaling of output overload and junction overtemperature and there may be an additional thermal sensor to detect extreme case temperature. The gadget is designed to fulfill IEC 61000-4-2 ESD, IEC 61000-4-4, and IEC 61000-4-5 specs for ESD, fast-transient, and surge immunity.
For quick analysis, the X-NUCLEO-OUT15A1 enlargement board incorporates an IPS1025HF with related circuitry prepared to hook up with STM32 Nucleo improvement boards. An indication firmware pack, STSW-OUT15F4, and industrial-automation system design GUI, STSW-IFAPGUI, are additionally out there and allow customers to comprehend a whole industrial-automation surroundings on the desktop.
The IPS1025HF is in manufacturing now, out there in each PowerSSO-24 and QFN48L packages, priced from $3.51 for orders of 1000 models.
