All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC). Typical values are at T A = 25°C, V DD = 3.6 V.
This is the V DD input voltage range over which the rest of the specifications are valid. The part operates as expected until V DD goes below the UVLO threshold.
This is the current into the V DD pin. Additional current can flow into the indicator LED or HPLED, depending on the mode selected.
INTF should be tied to GND (INTF = 0) for I 2 C interface or to V DD (INTF = 1) for hardwire interface. All other digital inputs are 1.8 V compatible.
This bias current is active only when the high power LED and/or indicator LED functions are enabled.
This specification is not valid during minimum on-time operation of the boost converter (one LED case) when excess voltage is dropped across the HPLED pin.
This specification is not production tested but is based on bench evaluation. It is based on the typical two-LED application circuit using a 100 kΩ resistor from SETF to GND,
and a 160 kΩ resistor to a 1.8 V Tx mask logic signal with <1 μs rise/fall time. HPLED register = 11001 (binary). The inductor current has settled to within ±5% of final value.
