GENERAL DESCRIPTION The W83391TG is a DC Fan Pre-Driver which was integrated charge pump to drive external Nchannel MOSFET instead of P-channel MOSFET/ PNP transistor. The W83391TG provides 3 channels Fan Control and easily couples with Super I/O or hardware monitor to perform the control of DC Fans. W83391TG is available in a SOP-14 Pb Free and Halogen Free package. 2. FEATURES z Provides 3 channels Fan Control z Integrated Charge Pump and Can Support Up to 24V Gate Voltage for Driving External Nchannel MOSFET z Pairing with Nuvoton Series Super I/O and Hardware Monitoring IC for DC Fan Voltage Regulation z External Resistors for Output Voltage Scale Adjustment z Provides Pb-free and Halogen Free SOP-14 Package 3.

As long as the output capacitor is large (>100µF) and so is its ESR (>20mΩ), then it should be stable for loads as low as 10mA up to at least 4A. If a smaller value of capacitance and/or ESR is desired, then special considerations may be required to add external compensation capacitors and next to external power MOSFET. -3- Publication Date: Apr., 2010 Revision 0.55 W83391TG 6.
