What are the key features of ST-ONEMPTR?
- Fully integrated multiport smart charger controller manages multiple charging ports simultaneously from a single IC, reducing BOM complexity
- Linear battery charger architecture with per-port current control supports USB charging standards for consumer electronics applications
- Small outline package (SOP) simplifies PCB layout and enables compact charger designs for portable and wearable devices
- Intelligent port detection and power management enable automatic current allocation across 2 or more charging ports
What is ST-ONEMPTR used for?
The ST-ONEMPTR is designed for multiport USB charger hubs, desktop charging stations, and portable power banks that need to simultaneously charge 2 or more lithium-ion or lithium-polymer battery cells or connected devices. Its integrated linear charger controller manages per-port current distribution, simplifying firmware development for smart charging applications in consumer electronics and IoT accessories. The small outline package keeps charger PCB area minimal in slim multi-port wall adapters and automotive USB charging modules.

Frequently Asked Questions
How many charging ports can the ST-ONEMPTR control simultaneously, and what battery chemistry does it target?
The ST-ONEMPTR is designed to control multiple charging ports simultaneously — typically 2 or more — within a single integrated IC for lithium-ion and lithium-polymer battery charging applications. Its linear battery charger architecture supports per-port current regulation, making it suitable for smart hubs and USB charging stations that serve multiple Li-ion cells at the same time.
In which product categories does the ST-ONEMPTR linear charger approach outperform a switching-mode alternative?
The ST-ONEMPTR linear charger is preferred over switching-mode solutions in low-power USB charger applications where the input-to-output voltage differential is small — typically less than 2 V — because linear regulators produce no switching noise. This makes it well-suited for noise-sensitive audio accessories, wearables, and medical-grade portable devices where EMI from a 100 kHz–1 MHz switching converter would require additional filtering.
What lead time and availability constraints should procurement teams plan for when sourcing the ST-ONEMPTR?
The ST-ONEMPTR has a factory lead time of 24 weeks from STMicroelectronics, which is significantly longer than the 8–13 week lead times of many analog ICs. Procurement teams should place orders at least 6 months ahead of production start and consider safety stock of at least 3–4 months of consumption to avoid line-stop risk, particularly for products with annual volumes above 10,000 units.
