Frequently Asked Questions
Which input sources are supported by LM3658SD-B/NOPB and what voltage range is required?
The LM3658SD-B/NOPB accepts two input sources, USB 5 V and an AC adapter, over a 4.5 V to 6 V input voltage range. The dual-input architecture automatically selects the available source, making it ideal for portable devices that alternate between wall charger and USB charging in consumer and industrial handheld applications.
How does the LDO mode in LM3658SD-B/NOPB benefit system power management?
LDO mode in LM3658SD-B/NOPB allows the IC to draw power directly from the input rail and supply system loads without relying solely on the battery. This extends battery life by up to 30% in light-use scenarios and allows a device to operate with a discharged battery when a 4.5 V to 6 V input source is connected.
What protection features does LM3658SD-B/NOPB include for battery safety?
The LM3658SD-B/NOPB incorporates a 5-hour maximum charge safety timer and a 4 V automatic restart threshold. If the battery voltage falls below 4 V after a charge cycle completes, the IC restarts charging automatically. The safety timer prevents overcharge conditions, protecting lithium-ion cells rated at 4.2 V full charge from damage in consumer devices.
How compact is the LM3658SD-B/NOPB package for wearable PCB designs?
The LM3658SD-B/NOPB uses a 10-pin LLP (S-PDSO-N10) package with a footprint of approximately 2x2 mm and a height under 0.8 mm. This ultra-compact size fits easily in smartwatch and fitness tracker PCBs with limited board area, enabling dual-source Li-Ion charging without sacrificing space for other components.
