General Description
The Supertex HV440 is a monolithic integrated circuit capable of
generating up to 70V RMS sine wave output at frequencies of
15Hz to 60Hz with a load of 5 North American RENs. Its output
rating can be enhanced to 20 North American RENs with the
addition of two Supertex MOSFETs: one N-Channel MOSFET,
the TN2524N8 and one P-Channel MOSFET, the TP2522N8.
The high voltage output P- and N-Channel transistors are con-
trolled independently by the logic inputs P
the mode pin to ground will enable the device to be controlled with
a single input, N
logic to avoid cross conduction on the high voltage output. A logic
high on N
Channel off. The high voltage outputs have pulse by pulse over
current protection set by two external sense resistors. Nominal
PWM logic input frequency is 100KHz.
