PACK -
• Applicable in battery packs which require a high current level.
• During charge cycle Q2 is on and Q1 is off. Schottky can reduce power loss during fast charge.
• During discharge Q1 is on and Q2 is off. Again, Schottky can reduce power dissipation.
• Under normal operation, both transistors are on.
