Alpha & Omega Semiconductors app note about MOSFETs used in battery protection circuits. Link here (PDF) Power MOSFETs are required to be connected in series between the lithium-ion battery pack and the output load. At the same time, a dedicated IC is used to control the on and off of the MOSFET for managing the […]

App note: Digital control of surge voltage and inrush current in battery operated circuits
App note from IXYS on their battery operated surge voltage and inrush current protection circuit implementation. Link here (PDF) Primary concerns with battery-operated devices include battery protection from inrush and short circuit currents caused by connected load, and load protection from voltage spikes when battery load dump occurs, which may cause significant voltage stress on […]
App note: bq77905 20S cell stacking configuration
Application note from Texas Instruments on their bq77905 ultralow power stackable battery protector. Link here (PDF) The bq77905 is a 3-5S Low Power Protector with easy stacking capabilities for higher than 5S cell battery packs. This document provides an example for setting up a stacking configuration with the bq77905 and exhibits detailed analysis of the […]
