Applications

► Line access cards ► Set-top/Street box General Description The Supertex HV430 is a high voltage PWM ring generator integrated circuit. The high voltage outputs, V PGATE and VNGATE, are used to drive the gates of external high voltage N-channel and P-channel MOSFETs in a push-pull configuration. Overcurrent protection is implemented for both the P-channel and N-channel MOSFETs. External sense resistors set the over-current trip point. High-Voltage Ring Generator The RESET input functions as a power-on reset when connected to an external capacitor. The FAULT output indicates an overcurrent condition and is cleared after 4 consecutive cycles with no overcurrent condition. A logic low on RESET or ENABLE clears the FAULT output. It is active- low and open-drain to allow wire OR’ing of multiple drivers. P GATE and N GATE are controlled independently by logic inputs PIN and NIN when the MODE pin is at logic high. A logic high on PIN will turn on the external P-channel MOSFET. Similarly, a logic high on NIN will turn on the external N-channel MOSFET. Lockout circuitry prevents the N and P switches from turning on simultaneously. A pulse width limiter restricts pulse widths to no less than 100 - 200ns. For applications where a single control input is desired, the MODE pin should be connected to SGND. The PWM control signal is then input to the N IN pin. A user-adjustable deadband in the control logic ensures break-before-make on the outputs, thus avoiding cross conduction on the high voltage output during switching. A logic high on N IN will turn the external P- Channel MOSFET on and the N-Channel off, and vice versa. The IC can be powered down by applying a logic low on the ENABLE pin, placing both external MOSFETs in the off state.

Fault is at logic low when either current limit sense pin, VPSEN or VNSEN, is acti- vated. Remains active until overcurrent condition clears or ENABLE = 0 or RESET = 0.

3 MODE

Logic mode input. 0 = single-control; 1 = dual-control. When MODE is high, NIN and PIN inde - pendently control NOUT and POUT, respectively. When MODE is low, NIN controls both outputs in a complementary manner. (See Truth Table) 4 PIN Logic control input. When mode is high, logic input high turns on the external high voltage P-chan- nel MOSFET. Internally pulled low. 5 NIN Logic control input. When mode is high, logic input high turns on the external high voltage N-chan- nel MOSFET. Internally pulled low. 6 ENABLE Logic enable input. Logic high enables IC. Internally pulled low.

7 RESET

Power-on reset. A capacitor connected between this pin and ground determines the delay time between application of VDD and when the device outputs are enabled. Low leakage tantalum recommended.

8 DEADBAND

A resistor between this pin and ground sets the ‘break-before-make’ time between output transi- tions. Applicable only in single-control mode. For minimum deadtime, a 5.6kΩ resistor to ground should be used. For dual-input mode, tie to VDD. 9 SGND Low voltage logic ground. 10 PGND High voltage logic ground. 11 VNN2 Negative gate voltage supply. Generated by an internal linear regulator.
