STMicroelectronics’ IPS4140HQ and IPS4140HQ-1 are richly featured four-channel intelligent power switches, combining a compact 8 mm x 6 mm footprint, 80m? RDS(on) (max.) per channel, and 10.5V-36V operating range with extensive diagnostic and protection features.
The?TSZ151?op amps have very low?offset voltage with minimal temperature?drift, offering high accuracy and stability?to circuits for sensor interfacing, signal?conditioning, and current measurement.
The?STPMIC25?power-management IC for STM32MP2 microprocessors is now available, with 16 channels to supply all the MPU power rails as well as system peripherals in one convenient package. Completing the hardware design requires only a small number of external components to provide filtering and stabilization and the STEVAL-PMIC25V1 evaluation board is available now to start development immediately.
TS3121?and?TS3121A?rail-to-rail, open-drain, single channel comparators feature a novel failsafe architecture and guaranteed start-up time that simplify powering up for short periods to minimize consumption in low-power applications.?Ideal for use in industrial controls, building automation, power tools, smart metering, as well as in automotive powertrain and body-control modules.
ST’s?DCP3601?miniature monolithic buck converter combines extensive feature integration and flexibility, enabling simple, low-BOM designs to achieve high conversion efficiency. The power switches and compensation are built-in, requiring only six components to complete the circuit, including the inductor, bootstrap and filter capacitors, and feedback resistors for setting the output voltage.
STMicroelectronics’?TSC1801?low-side current-measurement amplifier integrates matched resistors to set the gain, which simplifies the circuit design, saves bill-of-materials costs, and ensures gain accuracy within 0.15% over the entire temperature range. The fixed gain also eliminates production trimming of external resistors.
STPOWER?MDmesh?DM9 AG automotive-grade 600V/650V super-junction MOSFETs?deliver high efficiency and ruggedness for?on-board chargers and DC/DC converters in?both hard- and soft-switching topologies.
Accelerating the design of gallium-nitride (GaN) power supplies (PSUs) that deliver superior efficiency and power density, STMicroelectronics has launched the?EVL250WMG1L?resonant-converter reference design based on the MasterGaN1L System-in-Package (SiP).
ST’s?VIPerGaN65D?flyback converter, with its SOIC16 outline, permits extremely small and economical power supplies, adapters, and USB-PD (Power Delivery) fast chargers up to 65W with universal input voltage.
