Here's the Circuit, as shown in fig1, There's Supply from adapter(9.5V DC), there's also a supply from the battery(8.4V Max). Diodes used(D1,D2) are shottky diodes, with a typical drop of (0.3V-0.5V). The problem i was facing was even though battery voltage at given point of time is less than Adapter Voltage(ADPT), At TP3, I was still getting battery Voltage.
The issue was resolved when Implemented the same circuit with a small change(Adding a resistor RL1), as shown in fig2.
Queries:
1. I would want to know what was the issue with the circuit in fig1 and how did it get resolved in fig2?
2.Is there a batter solution to the given problem ?
Part Numbers Used:
D1,D2 : SK85
U4: Pmk35EP,518
LI-Ion Battery (7.4V, 8.4V Max)
