Description
A resistor at this pin programs the on-board oscillator. If an external clock is being used, this pin should
be connected to VDD.
This pin is the clock input for the HV9986. The input to the CLK pin should be a TTL compatible square
wave signal. The three channels will switch at 1/12th the switching frequency of the signal applied at
the CLK pin. This pin is used if more than one HV9986’s are being used in a system. If the on-chip
oscillator is being used, this pin should be connected to GND.
These pins are the gate drivers which drive the external logic-level, N-channel boost converter MOS-
FETs.
Ground return for each of the channels. It is recommended that all the GNDs of the IC be connected
together in a STAR connection at the input GND terminal to ensure best performance.
