2.0 PIN DESCRIPTIONSThe pin details of HV9901 are listed on Table 2-1. SeeSection “Package Type” for the location of the pins.

TABLE 2-1: PIN TABLE Pin Number Symbol 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 oscillator to other HV9901s or to an external clock

8 RT A resistor from this pin to ground sets the PWM switching frequency.

9 POL Input that determines the polarity of the ENI input. See Section 1.1 “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 VCCOutput of the auxiliary regulator. The 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 Equation 3-8.15 VREF Reference Voltage. Bypass locally with a 10 nF capacitor.

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

Note the following details of the code protection feature on Microchip devices:• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of ourproducts.
