Low-current PMICs in AKM’s AP4413 sequence allow environment friendly battery charging in gadgets that sometimes use disposable batteries, together with distant controls, IoT sensors, and Bluetooth trackers. With present consumption as little as 52 nA, they’ve minimal impression on a system’s energy funds—essential for vitality harvesting functions.
The sequence includes 4 variants with voltage thresholds tailor-made to widespread rechargeable battery sorts. Every gadget integrates voltage monitoring to stop deep discharge, enabling fast startup or restoration. An inline capacitor permits the AP4413 to keep up operation even when the battery is absolutely discharged, whereas recharging it concurrently.
System configuration instance.
The AP4413 PMICs are in mass manufacturing and are available in 3.0×3.0×0.37-mm HXQFN packages.
The publish PMICs optimize vitality harvesting designs appeared first on EDN.
