General Description
The Supertex HV440 is a monolithic integrated circuit capable
of generating up to 70V RMS sine wave output at frequencies
of 15 to 60Hz with a load of 5 North American RENs. Its
out putrating 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
controlled independently by the logic inputs PIN and NIN.
Connecting the mode pin to ground will enable the device
to be controlled with a single input, NIN. This adds a 200ns
deadband on the control logic to avoid cross conduction on
the high voltage output. A logic high on NIN will turn the high
voltage P-Channel on and the N-Channel off. The high voltage
outputs have pulse by pulse overcurrent protection set by two
external sense resistors. Nominal PWM logic input frequency
is 100KHz.
