ISL6292D
Electrical Specifications
Typical values are tested at VIN = 5V and 25°C Ambient Temperature, maximum and minimum values are
guaranteed over 0°C to 70°C Ambient Temperature with a supply voltage in the range of 4.3V to 6.5V, unless
otherwise noted. (Continued)

NOTES:
3. The POR falling edge voltage is guaranteed to be lower than the Trickle Charge Threshold Voltage (V_MIN) by actual tests.
4. The actual charge current may be affected by the thermal foldback function if the thermal dissipation capability is not enough or by the on
resistance of the power MOSFET if the charger input voltage is too close to the output voltage.
5. Guaranteed by design, not a tested parameter.
