Charge Current Thermal Foldback
The charge current thermal foldback is a key feature of the
ISL6291 charger. Figure 5 demonstrates how the charge
current reacts to a temperature rise in the charger. The
charger starts with 5V input voltage a 1A charge current. The
VBAT pin voltage is set at 3.5V. Then the input voltage jumps
to 10V, generating more heat in the charger IC. As the
internal temperature rises, typically to +100°C, the charge
current starts to fall and stabilize, to approximately 600mA,
to lower the heat generation.
Summary
This application note described in detail the ISL6291EVAL1
evaluation board. The typical behavior of the start-up, a
complete charge and recharge cycle, the TIME pin
waveform, and the charge current thermal foldback are
demonstrated. The complete layout, schematic and the
bill-of-materials for the evaluation board are also provided.
