App note: Li-ion battery and gauge introduction

Sunday, October 7th, 2018

Richtek app note for Li-ion battery definitions and gauge introduction. Link here SOC is defined as the status of available energy in the battery and usually expressed as percentages. Because the available energy change depends on different charging/discharging currents, temperatures and aging effects, the SOC could be defined more clearly...

App note: Designing applications with Lithium-Ion batteries

Sunday, August 26th, 2018

More Li-ion battery applications from Richtek. Link here (PDF) Lithium-Ion batteries have several advantages when compared with other battery types: They are light weight, and energy density of lithium-ion is typically twice that of the standard nickel-cadmium. Li-Ion batteries have no memory effect, and the self-discharge is 6 ~ 8...

App note: High-speed lithium-ion battery charger

Sunday, April 22nd, 2018

C8051F300 implementation of Li-Ion battery charger from Silicon Labs. Link here (PDF) Driven by the need for untethered mobility and ease of use, many systems rely on rechargeable batteries as their primary power source. The battery charger is typically implemented using a fixedfunction IC to control the charging current/voltage profile....

LiTiny- A Tiny LiIon charger for most things battery

Wednesday, July 1st, 2015

Rohit Gupta made this LiTiny project, a tiny LiIon charger: In the end I had a LiIon charger capable of charging batteries @700mA restricted due to thermal dissipation limits of home made PCBs. Project details at Rohit's blog.

3.7V Li-Ion battery charger circuit

Monday, March 2nd, 2015

From the comments on our earlier standalone Linear Li-Ion battery charger with thermal regulation in ThinSOT app note post, Jan writes: Nice chip, indeed. Unfortunately not easy to find stocked – here I can get it only from Farnell (5 euro + VAT a pop) or Digikey ($3/pc + VAT +...
