Fan Control IC provides variable speeds.
ZXBM2000 series of ICs controls 2-phase, dc brushless fan and blower motors up to 100W. ZXBM2003 provides frequency generator rotor speed output; ZXBM2002 offers locked rotor error output; and ZXBM2M001 combines both signals on dual function pin. All deliver up to 80 mA to pair of external MOSFET or bipolar transistors connected to fan motor windings. Speed control is implemented via variable...

DC-DC Converter generates regulated output.
Switched-capacitor ZXCP330E6 provides 3.3V output from 2 to 4.4 V input with maximum load current of 40 mA. Short-circuit and thermal-overload protected, SOT23-6 packaged converter suits lithium-ion and alkaline battery-powered products. Operating with flying capacitor of 220nF and 10 microF bypass capacitors at input and output, typical PCB area requirement is 8 x 5.3 mm. It draws 20 microA...

Current Sense Monitor operates with 20V to 2.5V inputs.
Model ZXCT 1010 comes in SOT23 5-pin package, and measures load current with its high side sense resistor. Monitoring voltage across its shunt resistor and translating it into proportional output current, this current sense monitor IC uses 1 scaling resistor to convert proportional current into ground referenced output voltage. Features include separate pin to ground that produces output offsets...
