Linear Li-Ion Charger provides charging current to 2.0 A.
Tailored for single-cell Li-ion batteries, Model AQ9102 can be powered from ac voltage source adapter or USB port, and will automatically select correct source. During charging, unit will actively adapt to system load changes and re-allocate available current to either system or battery. Model AQ9102 requires no external blocking diodes or current sense resistors. It includes battery temperature...

LED Driver provides 120 mA of programmable output current.
Suited for white LED backlighting, Series AQ consists of 2-channel, dual-gain current regulators with inductorless, 1-1.5x charge-pump circuit. Each LED's driver current is matched to within 2% for uniform LED intensity and color. Driver operates over Li-Ion input voltage of 2.7-6.0 V, with undervoltage lockout. It features fixed 650 kHz frequency, and in full shutdown mode, draws only 10...

Power Regulator IC supplies power for wireless chipsets.
Model AQ9107 features input voltage of 3.0-3.6 V. Outputs include regulated 1.8 V with up to 500 mA for Baseband processor/MAC, 2.84 V with up to 300 mA for analog functions, and ultra-quiet 2.84 V with up to 200 mA for powering VCO. Microprocessor supervisory RESET function with complimentary output and adjustable reset delay time is included. Regulator features internal over-temperature and...

LED Driver provides 4.5 V regulated output.
Model AQ9156 features 1.5X charge-pump circuit that uses 2 ceramic bucket capacitors and 2 filter capacitors for VIN and VOUT. Unit drives up to 6 parallel white LEDs, with typical operating input voltage from 3.0-6.0 V. It offers selectable switching frequency of 8, 32, 262, or 650 kHz. LED brightness can be adjusted via applying PWM signal on either ENA pin or CLK2 pin. Internal...
