5621V General Description
The LA5621M and LA5621V are external charge control ICs for lithium-ion batteries. These ICs are ideally suited for on/off control of external power MOSFETs in systems that incorporate a charging circuit in the set. They detect the charge and discharge status, output it to the set control microcontroller, which then outputs a signal to switch external power MOSFETS either on or off. Moreover, these ICs have a built-in function that detects discharge (countercurrent) from lithium-ion batteries within sets to external lithium-ion batteries in an AC adapter/charger, etc. and switches external power MOSFETs off

5621V Features
• The combination of a microcontroller and external power MOSFETs enables easy charge/discharge control of lithium-ion batteries.
• Small power dissipation makes these ICs suitable for sets that require long time operation
• Use of compact package makes these ICs suitable for compact sets.
• Large power supply operation range supports both 1-cell and 2-cell lithium-ion batteries.
5621V Typical Application
• Charge control of 1- or 2-cell lithium-ion batteries of video cameras, digital still cameras, cellular telephones, etc., used in combination with a microcontroller.
