High Voltage
Ring Generator IC
Features
220V maximum operating voltage
Integrated high voltage transistors
Up to 70VRMS ring signal
Pulse by pulse output over current protection
5 REN output capability
External MOSFETs enhance output rating to 20 REN
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.
Applications
Microcontroller or microprocessor controlled high
voltage ring generator
Set-top/street box ring generator
Pair gain ring generator
Wireless local loops
Fibre in the loop/to the curb
Coax cable loop
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.

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
referenced to device ground.
