    Notice: Stresses above those listed under Maximum Ratings may cause permanent damage to the device. This is a stress rating only, and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

    Note 1: All voltages are referenced to GND.2: For operation above 25C ambient, derate linearly at 7.5 mW/C.

  • HV99012.0 PIN DESCRIPTIONThe pin details of HV9901 are listed on Table 2-1. SeePackage Type for the location of the pins.

    TABLE 2-1: PIN TABLE Pin Number Pin Name Description

    1 VIN Input supply2 Pin not present3 Pin not present4 GT Gate driver output for driving the external switching MOSFET5 CS Current sense input6 GND Ground

    7 SYNC Open-drain input/output for synchronizing the internal PWM oscil-lator to other HV9901s or to an external clock

    8 RT A resistor from this pin to ground sets the PWM switching fre-quency.

    9 POL Input that determines the polarity of the ENI input. See Truth Table.10 ENO Enable output. It is the logical inversion of the ENI signal.

    11 ENI Enable input. Whether ENI is active low or active high is deter-mined by the POL input.

    12 VCC Output of the auxiliary regulator. Output voltage is determined by the resistive divider connected to the FB pin.13 FB Feedback input for the auxiliary regulator.

    14 H/D HOLD/DELAY input. An RC network connected to this pin controls the pull-in time and the holding current. See equations on page 4.15 VREF Reference voltage. Bypass locally with a 10 nF capacitor.

    16 VDD Output of the internal supply regulator. Bypass locally with a 10 nF capacitor.
