HV440

The Supertex HV440 is a monolithic integrated circuit capable of generating up to a 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 controlled independently by the logic inputs PIN and NIN. Connecting the mode pin to ground will enable the device HV440 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 N_IN will turn the high voltage P-Channel on and the NChannel 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.
